OpenShot 2.4.4 Released | Keyframe Scaling, Docking, and More!
Written by Jonathan on March 20, 2019 in Releases.

I am proud to announce the immediate release of OpenShot 2.4.4, the absolute best version yet! This is going to be a long post, but here is a quick summary for those who are short on time. This release brings huge performance and stability improvements, along with some major bug fixes, lots of polish, and many new features.

>> Download v2.4.4 Now <<


Keyframe Scaling
This is perhaps one of the best bug fixes included in this release. Keyframes contain actual frame numbers and their values, and thus, switching to different frame rates and/or exporting to different frame rates, has many unexpected consequences, such as every single keyframe coming too early or too late. This is now fixed, so keyframes and animations are correctly scaled when changing frame rates!

Timeline & Preview Performance
Stability and performance are extremely important for OpenShot, and historically have been our greatest technical challenge. As usual, lots of improvements have been made in this area. Some of the stand-out improvements include: special handling for certain audio files to better handle the 1-frame video track, updated Angular and timeline speed improvements, improvements to image caching, and improved “missing frame” logic which helps prevent freezes while searching for a frame which will never come.

Improved SVG Rendering
OpenShot is now compatible with resvg, an amazing SVG rendering library. A big thanks to RazrFalcon for helping us with the integration! This improves our SVG overlay and title rendering, supporting much more of the SVG standard. The resvg library is included with our official downloads and installers, but might take much longer to reach official Linux repositories (since resvg is not available in many repos). Hopefully the integration with OpenShot will help resvg move in that direction.

Improved Docking & Tracks
One of the most significant updates to docking is the new full size properties widget, which can be on the left or right side of OpenShot. This displays more information without scrolling as much, and is very useful when editing or animating. A big thanks to Frank Dana (ferdnyc) on making this a reality. Also, many improvements have been made when inserting a new track, which makes it extremely fast even on huge projects, and easy to “undo” if needed. Also, many bug fixes relating to “Track Name” are included, and custom named tracks are supported on all dialogs.



Improved Windows Installer
If you have previously experienced issues launching OpenShot on Windows, we have created a new wiki article with troubleshooting steps. In addition, our Windows installer now looks for conflicting DLLs, and renames them during install, and should resolve a great number of issues. These conflicting DLLs are being added to System32 by some unknown 3rd party software (which should never be done), and are superseding the ones included with OpenShot. This can also easily be reversed (since we just rename the files). However, in general, our new Windows installer should help a bunch of people who previously could not launch OpenShot.

Relative File Paths
Once a project file (*.osp) is saved in version 2.4.4, some magic happens. All file paths are converted into relative paths, even paths contained in the undo/redo history, thumbnail paths, file paths, and any other paths found in the project data. Upon re-opening your project, all paths are once again converted into absolute file paths. This allows a project folder to be completely portable, and can be moved on the same machine, can be moved to another machine, and even another operating system… and will still open just fine! This “kind of” worked before, but should now work excellent and with great stability.

User-Defined Export Presets
Have a favorite export preset that is not included in OpenShot by default? No problem. Just create a text file in the /users/USER/.openshot_qt/presets/ folder. You can copy one of our existing presets to get you started. Next time you launch OpenShot and open the Export dialog, you will see your custom preset listed.

New Languages: Hindi, Arabic, Chinese
For many years I have dreamed of including full Hindi, Arabic, and Chinese (Simplified and Traditional) support in both OpenShot and openshot.org. I was finally able to help fund this effort, to help out the OpenShot translator community, and help get us to 100% complete translations in all 3 of these languages. I am very proud of this, and hopefully this effort will help engage people from these languages, and introduce OpenShot to a whole new world of people!



Constant Rate Factor Support (CRF)
We have added support for constant rate factor, which required some refactoring of libopenshot::FFmpegWriter. A big thanks to Peter (you are the best)! This can be utilized in any export preset, and is currently used by our VP9 preset.

Integrated Changelog
Do you ever wonder what changes are included in your currently installed version of OpenShot? Now you can find out! Use the Help->About OpenShot->Changelog dialog, and you can quickly see what commits, the date of each commit, and you can even right click and view the GitHub commit information. I know I might be the only person excited by this, but yay!



Waveform Improvements
When splitting clips which displayed waveforms, the newly split clip would no longer display any waveform data. This has been a long time bug report, and is finally fixed in this release! Thanks to everyone for patience on this one, and I’m glad that it’s finally resolved.

Improved Release Testing
One of my goals for 2019 is to make the development process for OpenShot as transparent as possible, and document absolutely every detail of OpenShot’s release cycle, release testing, and release flow. Included in this documentation is a completely new process for testing OpenShot before a release. Instead of this task being done primarily by myself, I’m hoping that this more transparent and documented approach will allow other contributors to fully test OpenShot and help me out in this area. And for the record, I successfully completed the new release testing process for all 3 OSes (Linux, Mac, and Windows). I actually found many issues while working through the testing plan and resolved them all prior to release. It felt great to actually see the validation of why a more rigorous testing plan is necessary.

New User Community
Over the past few months, our long-time user community / forum (http://www.openshotusers.com) died. Where can a new user ask questions? Where can users have rich discussions on problems, requested features, work-arounds, ideas, etc…? Introducing the official OpenShot subreddit: https://www.reddit.com/r/OpenShot/. So, please join the community, help answer questions, and hang out with us OpenShot people!

Full-Time Development
After giving more than 10 years of my life to this project and this community, I am finally working full-time on OpenShot. I had only dreamed of OpenShot becoming a full-time career, but I am so incredibly humbled and honored that OpenShot continues to grow, improve, and that I have scratched together enough money to work on this full-time! Hold on tight, because 2019 is going to be the most significant one yet for OpenShot!

Get Involved
Have you been casually following OpenShot for a long time? Do you have amazing ideas for improving OpenShot? Do you want to help spark “video editing joy” in the world? Send an email to hello@openshot.org and introduce yourself. It’s really that easy to get involved with OpenShot on any level, and you certainly don’t need to be a programmer either. All skills, all skill levels, and all people are welcome to join our developer community, share ideas, laugh, and make OpenShot more awesome! Still not convinced or just don’t have any time to contribute? You can always send a donation (and get your name featured in our credits)!

OpenShot 2.4.2 Released | More Effects, More Stable, More Fun!
Written by Jonathan on June 30, 2018 in Releases.

Happy summer! Version 2.4.2, the latest and greatest OpenShot Video Editor is now available (after a long wait), and we have lots of great improvements to share! We have exciting new effects, tons of bug fixes, and more stability and performance enhancements! Let's dive right in!



I am so excited about this release, and although it's been in development for a long time, it addresses so many important bugs and improvements! Let's start off with the highlights, and then below is a giant list with more details for those who are interested.

7 New Effects (Crop, Hue, Color Shift, Pixelate, Bars, Wave, Shift)
Each of these new effects could have their own blog posts and tutorials (and probably will soon). Each effect was created from scratch for OpenShot 2.4.2, and are all fully keyframable, and can be combined with each other. This creates millions of interesting possibilities (some combinations are shown in the video above). Animated pixelization boxes, animated cinematic aspect ratios, and so much more! As you can probably tell, I'm really excited about them!

Auto Audio Mixing
When enabled, clips can utilize 3 different audio mixing strategies, for cases when clips are overlapping and competiting for audio volume. For example, a background audio track can automatically lower its volume when an overlapping voice clip needs to play. It is currently disabled by default (on new clips), but can easily be turned on in the clip properties.

Auto Rotate
Photos or videos with rotation metadata will be automatically rotated in OpenShot (requires a somewhat newer version of FFmpeg though). Take a vertical video, or a horizontal photo with your phone, and likely it contains this rotation metadata... and OpenShot will display it correctly.

Improved Audio Playback
Audio playback and mixing has been an area of weakness for OpenShot, and continues to be an area of focus for improvements. Many bug fixes and improvements have been made, and many users will notice less popping, smoother mixing, and less issues in this area. But there is still work which needs to be done, and will continue to be improved further.

Improved Stability
With each release of OpenShot, stability continues to be improved. Most crashes are reported on Windows builds, although we still have too many crashes on all OSes. Some crashes are caused by dependencies, and some are caused by multi-threaded race conditions or memory corruption. Version 2.4.2 for windows is wayyyyy more stable now, and for the first time, is being offered as both a 64 bit and 32 bit version. Many schools still use older 32bit CPUs and have often requested this. Also, our 32-bit builds are now large memory aware, and can support more memory, making crashes much less likely for lower powered computers.

Improved Export Dialog
OpenShot's export dialog now displays progress in the window title, including some performance metrics (encoding frames per second and estimated completion time).

New Codec Support (including experimental)
AAC is now the default audio codec for many presets, which allows OpenShot to create videos which are more widely compatible with all OSes, devices, and web browsers. Also, experimental codecs supported by FFmpeg and LibAV can be used in OpenShot for the first time.

Growing Team of Developers
I am so proud of the volunteers who have been contributing their time to OpenShot over the past many months. Team OpenShot has slowly been gaining more contributors on GitHub, and our users have been so helpful in reporting bugs, updating GitHub tickets, and providing steps to help us reproduce issues. We are still struggling to keep up with the number of GitHub issues, and are trying our best to keep them grouped, de-duped, and organized by priorities. We could still use some help in this area, if anyone is interested!

Dramatically Improved Build System
OpenShot has migrated its build system to GitLab, and moved our development flow to GitFlow. We now have a world-class build system, new installers for every branch and every commit, integration with GitHub, LaunchPad, Slack, and openshot.org. This has been empowering our contributors to create custom branches with experimental features, and out pops 4 installers (Linux, Mac, Windows x86, Windows x64). We have a total of 6 servers now contributing to our builds, git synchronization, status checks, unit tests, and installers.

Join Us
If you enjoy OpenShot, or would like to see it improved in specific ways, please consider joining our team. All skill and skill levels are welcome, and there are a ton of ways to contribute: documentation, testing, GitHub issue management, programming in C++ or Python, art and design, translations, or maybe you just want to be a cheer leader or offer up ideas! The only requirement is a love for open-source and OpenShot. =) If you are unable to contribute with your time, you can also contribute with a donation, and get your name listed in the credits of OpenShot!

Full list of features / commits below:

libopenshot-audio 0.1.6 so:6
Fix under-linking (pthread and dl), fixes #3
Integration of GitLab build pipelines
libopenshot 0.2.0 so:15
Auto audio mixing strategy per clip (average, reduce, or none)
Adding new crop effect, which can also be animated for some very cool effects.
Adding new Color Shift effect, which can shift any color (RGBA) with infinite wrapping (and full supports animation).
Adding new Pixelate video effect, which pixelates a portion (or all) of a frame's image, and is fully animatable.
Adding new video effect: Bars, which allow for animating colored bars around your video, such as a letterbox effect.
Adding new wave video effect, which can be animated in a ton of ways to create lots of cool wave distortion effects.
Adding Hue video effect, to adjust the hue of a frame's image, which can also be animated with a keyframe
Adding new effect: Shift, an infinite pixel shifting effect which can be animated and wrap images in any direction.
Auto-Rotates any Clip with Reader metadata 'rotate' attribute.
Experimental codecs now supported in FFmpeg/LibAV
Audio popping during preview (due to resampling)
Fixing brightness and Mask effects to calculate factor with a float type, giving more fine control
Fix Blur.cpp by copying blur_<chan> values back to <chan> so horizontal *andvertical blurs can be applied in one effect and blur accumulates with increased iterations
Update and apply frame mapper on any clip changes, to keep timeline offsets in sync (i.e. avoid audio popping due to slight misalignments of clips on the timeline).
Removing old frames from WorkingCache (when no longer needed). This helps prevent freezing looking for old frame data on certain videos.
Adding metadata from format, audio stream, and video streams to ReaderBase.info, which in some cases includes the 'rotate' metadata added by certain cameras, and audio metadata like title, album, artist, copyright, dates, etc...
Added in metadata encoding capabilities (writer.info.metadata["title"] = "My Title"). Only certain tag names are accepted (see FFmpeg for more on which tags are supported by which codecs).
Optimize and improve speed of Mask effect (used by transitions). This is way faster than before!
Fixing assignement and copy operators on Frame class (to prevent crashes for unintiailized image and audio pointers), and ensuring both copy and assignment operators work as expected.
Fixing the color property of Frames, which was being lost on some constructors.
Increase valid frame rates to 240 fps since many cameras now support this higher frame rate
Fixing regression on Clip constructor, and simplifying pointer initialization
Fixing a bug with Frame::AddImage (convertToFormat) not actually doing anything. It returns a new image, and does not convert the format in-place.
Preventing crash if Seek invoked before QtPlayer are initialized properly
FFMPEG 3.2 support for FFmpegWriter
FFMPEG 3.2 support for FFmpegReader
Fixing FFmpeg version breakage in FFmpegWriter
Increasing the default amount of cache in FFmpeg, based on the # of processors, to better support high framerate videos.
Changing some Seek values to be more accurate, and fixes a race condition with Timeline_Tests.cpp.
Changing some sleep() calls to usleep(), for more accuracy. This is a bit experimental, and hopefully will work on all OSes.
Do not clobber gainFactor when determining volume adjustments and add a TODO note about current_max_volume always being 0
Removing anchor from clip properties (since it is unused)
Adding "dbghelp" dependency for Windows builds (for crash handling support), and improved Windows build instructions using MSYS2.
Properly set test media files path, fixes #36
Fixing black frames at end of video clips, if audio stream longer than video stream, and end-of-stream is reached.
Integration of GitLab build pipelines
Faster Windows builds
Fixing audio unit tests
Avoid mixing audio for clips with no volume or disabled audio.
Updating cmake file for libopenshot-audio to search $ENV first, and then static folders
Add missing type cast
Spelling and typo fixes
openshot-qt 2.4.2
More detailed export dialog progress, including estimate time remaining, FPS, and more accurate percentage. Thanks Peter!
Defaulting to AAC audio codec
Improving zoom scale calculation, to use a custom bezier curve (zoom gets faster and faster the more you zoom out). 30 levels of precision between 1 second and 7200 seconds.
Auto-rotate for Readers with 'rotate' metadata. This requires a slightly newer version of FFmpeg, otherwise the 'rotate' tag is never found.
Adding new Crop video effect
Adding new Color Shift video effect (with temp icon)
Adding Pixelate video effect, which can animate a pixelated version of part (of all) of a video clip.
Adding new Bars video effect, which allow for animating colored bars around your video, such as a letterbox effect.
Adding new Wave video effect
Adding Hue video effect
Adding new Shift effect (which allows for shifting the image in any direction and allows for animation, with infinite wrapping)
Support for 32-bit and 64-bit Windows builds, and an update to the Windows dependencies (and installer size reduction).
32-bit version of Windows is now large address aware, and can make use of more memory, but users might need to run this command first: 'bcdedit /set IncreaseUserVa 3072' in order to utilize this
No longer crash app if user settings cannot be read. Now we show a message box and reset the user settings.
Adding save indicator in window title
Retain track parameters during add/remove track
Update titles to be compatible with newer versions of Inkscape
Always apply mapper when opening a project, to ensure no audio starts popping for different framerate projects
Split Clip dialog now sends focus back to slider after clicking 'Start' or 'End' or 'Play' (to make it easier for frame-by-frame arrow keys)
Make clip and transition menus trigger on mouse-down, and not move the timeline item when the menu is activate
Removing max constrains from export length, so user can export blackness at the end of his project if so desired.
Disabling/Enabling save icon based on if the project needs saving
Add preset xml file for chromebook target
Removing unneeded 64-bit/32-bit clean-up code from Windows installer (which breaks on a 32-bit system)
Fix initial save indicator on a new (blank) project
Also use import_path for missing-file recovery

OpenShot 2.4.1 Released | Improved Playback & Image Quality!

I am proud to announce the release of our latest (and improved) version: 2.4.1. I would like to thank all the people who help and contribute to OpenShot, and make it a joy to work on. This is such a fulfilling project to be a part of, and I’m very humbled so many people find our project useful.
>> DOWNLOAD NOW <<

Improved Image Quality

We have improved the image processing pipeline in OpenShot to create sharper images, by switching our image scaling algorithm, and most importantly, only scaling a frame once, as opposed to multiple times (which used to happen in certain scenarios). This results in a noticeably sharper image, and slightly better performance.

Improved Playback Smoothness

The video preview capabilities in OpenShot have been improved to better handle higher framerate videos (50 fps, 60 fps, 120 fps). This results in a smoother playback experience, and less jittering and freezing with certain preview profiles.

Improved Stability (especially for Windows)

Right after our previous release (in September 2017) we made some very large changes to libopenshot to better support Windows (with respect to certain data types in C++). This fixes many, many Windows issues, including audio files stopping early, sync/desync issues, videos stopping at 30 minutes (or at an earlier time), opening project files with non-English characters, and more. If you have had any issues on Windows, please give this new version a try.

But is it really more stable?

Yes. Each release we fix actual stability issues, and continue to find race conditions, and add more protection around high risk code (such as image data). On certain systems, and with different combinations of video cards, CPUs, and OSes, some crashes happen often (which is less than ideal), and on other systems, it doesn’t crash at all. Each time we can reproduce a crash, we fix it, and the net result is statistically less crashes with each new version of OpenShot. We have reduced the # of crashes by a factor of 10 in the past 12 months, and will continue to work hard in this area.

New Video Tutorials

I am proud to announce a new series of video tutorials is in the works, and the first few are now available. I will be adding more videos very soon, and look forward to building a comprehensive collection of short (5 to 10 minutes) tutorials, covering all the features, secrets, and workflows built into OpenShot.



New Website Translations

As you might have heard me mention before, the OpenShot website is now available in different languages, and this has been really fun to work on. Bringing OpenShot to more languages and more people is exciting, so please check out the following translations, and help spread the word!

Help us with your language

Libopenshot (full list of changes)

More critical sections trying to prevent race conditions on high CPU core systems
Additional critical sections around adding frame images
Codec lookup by name in FFmpegWriter, which should solve a few issues (such as xvid support). Thanks Peter!
Fixing regression with rotation origin. Things should always rotate around the center of an object (until I add in keyframable anchor points)
Setting timebase on video stream in FFmpegWriter... a bit experimental
Improving playback smoothness on high framerate videos, especially when the video frames need to jump forward to keep up with the audio.
Removing throw statements from header files
Reducing # of scale operations to 1 per layer on the timeline
Fixing 16 thread limit on FFmpegReader
Fixing a cast from long to int64_t
Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. This is a big one!
Removing variable bitrate support (for now), since it causes more problems than it solves.

Openshot-qt (full list of changes)

Fixing small regression with translation website URLs when using default/en_US
Fixing small bug in Export dialog where profile and quality get blown away when changing format
Ignoring history update messages, since libopenshot doesn't care about them
Simplifying export progress, reducing # of signals being emitted
Integrating current language into website URLs and simplifying a few translations (removing HTML tags)
Removing unneeded UTF8 encode method, which caused certain project paths to fail when loading (solves crash on Windows trying to open non-English project file paths)
Fixing a big race condition on initial launch of OpenShot, which causes certain JavaScript calls to fail (so default profiles, snapping mode, and few other things set on launch would fail sometimes)
Adding keyboard shortcuts for toggling 'Transform' and 'Insert Keyframe'. This improves the animation work-flow, and no longer requires a bunch of mouse clicks / context menus for animations.
Preventing overwriting an input file with the export dialog, and updating export progress on export window title
Updating translations and contributor credits

OpenShot 2.4.0 Released | Improved Stability & More!

The latest and greatest version of OpenShot Video Editor (version 2.4.0) has been officially released, and I'm proud to bring you all the details! This is a stability-focused release, and much of the effort was "behind-the-scenes" type work.
Vastly improved stability, improved undo/redo history (now being saved inside each project file), new freeze and zoom menu, updated translations, and many bug fixes!

I have spent the past few months working along side a few other brave developers (huge thanks to Craig and Peter), determined to solve a very difficult stability issue, which is the leading cause of crashes in the OpenShot 2.x source code. The challenge was to isolate the crash, and find a way to reliably reproduce the crash in our development environments. This proved very difficult, and often we could run hours and hours of test code before a crash would happen. And of course, debuggers and analysis tools would slow the code down, and reduce the likelihood of a crash even more, often preventing the crash completely.

For those who want more technical details on the crash, please keep reading. The crash was a race condition and memory corruption bug, caused by a few different things. We process video and audio data in a thread pool, and sometimes things happen in a very unpredictable order. In a very rare condition, memory was being cleared while it was still being accessed. Also, we switched from an older tr1::shared_ptr to std::shared_ptr, and changed the way we initialize our shared_ptr instances, reducing the amount of memory being requested. Also, there were a few spots that needed to be protected between threads, and required locks. So, in summary, a handful of small changes, and a few months of debugging, and we can no longer crash libopenshot during video processing or video encoding! I'm very excited about solving this one if you can't tell!

Here is the full list of improvements:


openshot-qt (Video Editor)
Improving undo/redo support. Now the last X number of undo/redo actions are stored in the project file. The number can be adjusted in the prefences, under the auto-save tab. This also vastly improves the usefulness of the auto-save system, since it saves your undo/redo history as well.
Fixed Image Sequence exporting. Supports PNG, JPG, PPM, BMP and a few others. Also added 'Audio Only' and 'Video Only' export options.
Adding new Freeze and Freeze & Zoom presets, to quickly insert freezes into clips.
Removing 'show waveform' from separate audio menu, to increase speed of separating audio.
Protect file menu from invalid file_id.
Protect timeline dropEvent from empty item_id.
Cloaking timeline body until Angular loads fully (so we don't see the occasional pop-in debug layout).
Updating translations and supporters.
Bumping version to 2.4.0 (minimum libopenshot version 0.1.8).

libopenshot (Video Library)
Prevent crashes related to too many threads (on 24+ thread systems).
Migrating tr1 to std, adding C++11 support to build scripts, fixing crash in FFmpegReader (caused by shared_ptr, buffer, and last_video_frame corruption). Much improved stability with this change. Thanks to Craig and Peter for the help!
Fixing crash on Ubuntu build server.
Fixed a strange bug related to exporting image sequences. The filename property was not being set on the AVFormatContext. Also fixed a bug when exporting to JPEG image sequences related to max_b_frames and certain codecs.
Fixing issue with incorrect image size caches, which results in blurry/smudgy scaling on certain things.
Fix issue with loading time curves that are never processed (i.e. have no values)
Adding additional locks when adding/changing audio data. Reducing FrameMapper to a single frame at a time.
Fixing crash on Time keyframes where it would sometimes calculate an invalid frame number.
Fixing audio pops when stacking multiple clips with different offsets (pretty big issue for some people, just depending on your source framerates and position/start of clips).
Removing nested OMP processing from FrameMapper. Adding lock inside time mapping (to prevent crashes when speeding up/slowing down clips). Adding omp critial lock to Frame GetAudioChannelsCount() and GetAudioSamplesCount() methods.
Bumping version to 0.1.8 (SO version 13).

New 2.3.3 Release! New Everything!

I am proud to announce the release of OpenShot 2.3.3, which addresses many serious stability issues, and the launch of our amazing new website (www.openshot.org). It's been a busy month so far, and I'm super excited to roll out these improvements!

Improved Project Website (responsive, mobile-friendly, and fast)

Our new website has been in development for the past month (or so). It's built with Python/Django/PostgreSQL and runs on Amazon EC2. There are many custom features of our website that have accumulated over the years (PayPal integration, Bitcoin integration, Patreon integration, GitHub integration, donation back-end, Slack integration, openshot-qt exception reporting and version integration, contributor back-end, and more). Migrating all these features, and upgrading the UI took some time, but I'm very happy how it ended up.

Error Analytics

Over the past 2 weeks, I've done quite a bit of work aggregating up exception data for openshot-qt and libopenshot, and analyzing some key data points. I've targeted the top 25 crashes and errors, and version 2.3.3 should resolve them all! Below is an example of the analysis, which graphs the frequency of unhandled Python exceptions (including line number).

Version 2.3.3 Improvements

New release of openshot-qt! Bumping version to 2.3.3, and libopenshot depenency to 0.1.6
Adding CFBundlePackageType key to Info.plist, and symlinking a few files which I don't think are considered executables in the app bundle. A bit experimental, but trying to overcome an issue with Gatekeeper on OS X Sierra.
Fixed SpaceMovie 3D animated title alpha key frames, and adjusted the position of the main title to be better centered when it appears.
Fixing bug when selecting effect on a clip (where selection dropdown would not populate)
Fixed bug on certain systems when loading list of all supported languages.
Fixed backup recovery issue which would not refresh the timeline on load.
Fixed bug destroying the lock file (if another process already deleted the lock file).
Added C++ exception parsing from archived exception data.
Adding a script to parse and aggregate Python error logs for OpenShot
Another attempt to fix the race condition causing the "zipimport.ZipImportError: can't decompress data; zlib not available" when launching a frozen version of OpenShot.
Fixed a common error on the title editor (caused by a missing font-style).
Protecting query classes more, to prevent invalid clip/tran/effect ids from crashing
Removing NVidia driver from AppImage (build server)
Updated supporters and donors file
Updated translations and improved translation test script (which validates all string replacements are found in translations)
New release of libopenshot (0.1.6)
Fixing Timeline::SetJSON to use a lock, and reopen the reader if already open. This fixes an issue when trying to open another project while the current project is being accessed (i.e. during playback).
Adding additional lock on ClearAllCache method, to prevent crash
Fixing a data type issues with max()
Big improvement with handling invalid video and audio timestamps, defaulting to more sane values (when huge crazy timestamps are detected).
Fixing a bug when disabling video/audio tracks on FrameMappers.
Adding additional bail-out code when stuck searching for a video/audio packet that probably doesn't exist.
Added improved "checked frame" handling, and once 1 frame is detected as invalid, clean out any other invalid ones as well.

OpenShot 2.3.2 Released

Version 2.3.2 has been released this evening, and it addresses a few big issues.
Undo/Redo Crash

A very nasty bug related to deleting clips and then using undo to bring them back. The clips would appear to come back, but in reality, it was more like a zombie clip... just waiting to eat OpenShot's brains. Fixed.

Transform Crash

Apparently I'm not great at testing obvious things, like scaling a clip down to 0 pixels wide/tall. This resulted in a hard-crash. Fixed.

libopenshot Detection

One of the most common exceptions reported is related to an out-of-date libopenshot library. Sometimes, new methods are added to libopenshot, and if you only update the openshot-qt package, it's possible those new methods are not available. So, now openshot-qt checks the libopenshot version, and stops you before things get ugly. This will also help packagers test packages, and will quickly remind them to also update the libopenshot package.

Reduced File Size

Reduced source code file size, by further compressing images, removing unused translation resources, and a few other reductions. The result is smaller source code, smaller packages, and smaller installers.

Full list of changes:


Bumping version number, and updating minimum libopenshot version
Updating translations and supporters files
Prevent transform scale from dividing by zero
Fixing incorrect content-type on exception reporting
Fixed another bug when deleting, undoing, and then moving a clip. Similar to the previous bug fix... but now I think I got it fixed. Closes #590.
Fixing crash on undo/redo when deleting a clip... and other related crashes.
Adding in minimum libopenshot detection, since many linux distros only seem to be updating the PyQt packages, rather than libopenshot (This results in many crashes)
Fixing title on SpaceWars 3D title
Fixing bug when right clicking on a unselected timeline item, it does not fully select it
Attempting to fix a strange race condition when frozen with cx_Freeze, where some users get ZipImportErrors when calling loadUi(). This prevents that function from running at the exact same time, and hopefully will prevent the error.
Fixing small bug when trying to lock tracks on an older project file
Compressing transitions images more to reduce installer size
Removing unused translation files at run-time. Original PO and MO files can be found on LaunchPad: https://translations.launchpad.net/openshot/2.0. These bloat the installers for no real reason.
Changing name of toolBar to "Toolbar".
Adding a missing documentation image.
Updating translation template, and tweaking style of "Update Available" button which only appears when an update is available.
Capture multi-digit version numbers - merging


Version 2.3.1 released, fixes a couple bugs, updated translations, improved documentation. That is all. =)

OpenShot 2.3 Released | New Transform & Razor Tools!

I am proud to announce the newest release of OpenShot Video Editor, version 2.3! This is one of the biggest updates ever to OpenShot, and is filled with new features, performance improvements, and tons of bug fixes!
Download OpenShot 2.3

Take a quick look at our release video below, which highlights some of our biggest new features.

Also, check out this awesome 2D animation created by my daughter with OpenShot 2.3 (my kids are the best testers and are experts at breaking OpenShot)!

Transform Tool
We have added a new transform tool, which allows real-time transformations in the video preview window. Right click on any clip, and choose “Transform” to enable the tool. Using your mouse, move and scale the clip as needed, all while enjoying a real-time preview. Animating the location and scale of clips has never been easier!

Zooming Improvements
Zooming in and out of the timeline, in order to increase precision of your edits, has been greatly improved. When zooming the timeline, it now centers on your mouse position, similar to image editing applications. The zoom scale is also now saved in each project file, which saves some time when jumping back into a project. When your mouse is over the timeline, hold CTRL+mouse scroll wheel to zoom in and out.

Razor Tool
Back by popular demand, the razor tool from OpenShot 1.4.3 has returned from the dead. Click on the Razor toolbar button to switch to razor mode. Now click on any clip or transition to quickly cut them (holding CTRL and SHIFT modify the razor to only keep the left or right side). Alternatively, you can cut a clip at the Playhead position by right clicking and choosing “Slice”, by using CTRL+K, or by grabbing the edge of the clip and dragging.

Improved Title Editors
Many improvements have been made to the Title Editor and Animated Title Editor. Both editors now display a grid of thumbnails, to make finding the right title easier. Save dialogs are no longer used, and instead title files are saved directly into your project folder. New “Edit Title” and “Duplicate Title” menus have been added, to assist in quickly making changes to titles.

New Preview Window
Previewing files now has its own dedicated video player, which allows for multiple video preview windows at the same time. Also, audio files render a waveform by default. The speed of previewing files is also improved, using the improvements mentioned below.

Huge Performance Improvements for Real-time Previews
Performance improvements are always a high priority, and we’ve made some really great improvements to the speed of real-time previews. We’ve also fixed some bugs related to freezes and hangs, caching improvements, frame detection, and better logic to determine the max size of our preview window, so we can optimize by not rendering images and frames larger than the preview window. The end result is the best real-time preview performance yet for OpenShot.

New Documentation
I have finally gotten around to publishing a User Guide for OpenShot 2.x. I am using the Sphinx documentation system (which is really great), and I think this will be very useful for new users, and any user who wants to get the most out of OpenShot. It is currently only available in English, but I will soon start the translation process for it.



Audio Improvements
Fixes for audio sample distribution, caching, off by 1 errors, and various frame boundary improvements (Thank you Nelson H). Also, improvements to audio device management, which is how OpenShot communicates with the audio system on each OS.

Improved Export Dialog
Export dialog has been improved to re-load the project, clear cache, and export without requiring any ties to the real-time preview system. This fixes many freezes and hangs when attempting to export, and is a much more stable approach. Also, on Linux, export progress is now displayed on the launcher icon (in Unity and other launchers).

New Windows Build Server
As you might have heard, my Windows development system (and build server) died (again)... stopping all Windows builds for a few weeks. Hard-drive and motherboard issues (and possibly other problems too). A HUGE thanks to John Fields and his band of merry Open Source Saturday folks. They donated a wonderfully nice computer (i7, 16GB RAM), and their only request was that it be called StarLord! Done! StarLord is up and running, and is working beautifully!

GitHub Bug Management
With the help of a few volunteers (Ankit, Justin, Jt, and others), we’ve been able to reduce our GitHub bug count from over 380+ bugs to less than 200. Many of those 200 should be resolved with version 2.3, so I still have some work to do in this area, but making great progress! I’ve also added some GitHub templates when filing new bugs, to help increase the quality of new bug reports, and guide users on generating and attaching log files.

Translations
OpenShot 2.3 is fully translated in 11 languages, and partially translated in more than 60 others. If you notice untranslated text in your native language, please feel free to submit your own translations on LaunchPad.

100% translated in the following languages:
Spanish
French
Italian
Portuguese
Brazilian Portuguese
Greek
Ukrainian
Catalan
Malay
Icelandic
English (United Kingdom)


Patreon & PayPal Donations
If you use OpenShot, support OpenShot, or just want to ensure its continued development, please consider a small donation, or help us spread the word. It is expensive and time consuming to build and distribute OpenShot, and any contribution would be hugely appreciated!

We accept PayPal, Bitcoin, and Patreon donations, and we’ll list your name in the credits of OpenShot (which is pretty awesome)!

Additional Features
Added new welcome tutorial message, which contains a checkbox for disabling anonymous error and metrics reporting. That can also be adjusted in the Preferences, but it has been often requested to allow new users to opt-out.
All child windows now center on parent window
Ability to easily display frame numbers on frames
Improved accuracy when calculating frame numbers
Improvements to frame accuracy, especially when zoomed in at max zoom
Dramatically increased speed of selecting and unselecting large numbers of clips/transitions.
Refactor loading properties for selected items, to improve speed.
Refactoring and improving preview playback of files, and preview playback during resize/trim (which now maintains aspect ratio correctly).
Improving long filename support in file tree/list views, and improving thumbnail/grid view on all listviews (effects, transitions, titles, animated titles, etc...)
Updating translation files (with a few minor corrections to string formatting arguments).
Improving test_translations.py script, which helps me detect problems with missing formatting args.
Fixed an issue preventing the track names from being translated on launch.
Adding "width x height" to list of profiles on Export and Profiles screens, to make the output resolution more clear
Improved logic for "Next Marker" and "Previous Marker" buttons to include the selected items (start and end positions), to allow quickly jumping to the beginning or end of a selected clip.
Prompting user to find missing files when opening a project, and updating translation template.
Prompt user to save before creating or opening new project file (if needed)
Make effects container on a clip visible on hover (regardless of how small the clip is).
Tweak tooltips of clip title so they don't cover up the menu button and effects.
Making settings save to disk as they are changed in preferences.
Setting focus to Project Files on launch, so the properties filter doesn't auto get tab focus (preventing certain keyboard shortcuts).
Switching snapping logic to compare pixels (not time), so it's still useful at close and far zoom levels. Reducing snapping to 10 pixels. Fixing bug when updating new properties for a clip.

Bug Fixes
Fixed regression with selection dropdown
Fixed crash when pasting keyframes onto a clip/transition
Fixing incorrect placement of a selection handle
Fixed a bug when caching a mask size (a regression from some of our speed improvements)
Fixed small bug with Next Marker and Previous Marker buttons (not handling position 0 correctly).
Fixed bug in transform callback, where transformation was not being disabled when selecting a different clip.
Adding a lock when updating the JSON of a Timeline (or remapping it), so nobody can request frames while everything is changing. Seems much more stable during live preview.
Fixing invalid cache after editing effect in a clip, and frame accuracy (converting timestamps into frame numbers). This makes frame by frame editing much better.
Fixing broken gravity for GRAVITY_BOTTOM_LEFT
Fixed bug with Build server version detection regex (when releasing new versions).
Fixed a big bug when pasting deleted clips and transitions.
Refactoring some tracking code on initial install, and saving settings after launch (since some settings are updated on launch)
Always settings unique id when sending metrics, which is required or analytics ignores it
Fixing a crash during initialization of the main window, and a crash during application exit, where threads were not being terminated correctly or safely.
Fixed a crash when closing the Split Clip dialog.
Fix align_x bug in newer Blender versions (Thanks mixedbredie)
Updating Blender compatibility to 2.78, since the API has changed a bit. Also fixing the regex for detecting preview images from Blender, since the output from Blender is now a bit different.
Refactoring load project flow to take advantage of the new locks in libopenshot (which allow for quicker updates to the live preview after a change is made).
Fixed a regression detecting missing files that contain expressions (like blender animations).
Improve speed on Transform method, since it gets called quite often during project load (due to clearing selected clips and transitions)
Fixing regression with slicing clips (and razor tool).
Fixing regression on reading large log files (causing slow launch)
Fixing regression on passing keypresses to timeline. CTRL and SHIFT keys have special uses on the timeline.
Improve cutting/splitting dialog to use Timeline() object, to support all possible media types (images, videos, etc...) and maintain correct aspect ratio.
Removing unused files and unneeded translatable strings. Also, adding title names to translation template (forgot about those).
Removing old effect meta data and old effect icons. New effects will have different translatable metadata.
Removing uploads folder from mac build script
Removing app.processEvents from transitions and effects models, due to crashes on OS X. Also, it doesn't make much of a difference anymore.
Fixing weird bug preventing backup.osp from restoring correctly
Fixing bug with duplicate title when running in an non-English language
Improving logic to process files when importing (some were incorrectly marked as invalid)
Fixing bug when opening legacy projects (1.4.3) that contain effects or markers

OpenShot 2.2 Released | 4K Video Editing!

Happy Holidays to all the OpenShot supporters around the world! I am very proud to announce the latest and greatest release of OpenShot (version 2.2) has just arrived, and is ready to edit all your holiday videos! It’s faster, more stable, and better than ever!

Performance / Caching
Over the past few months, improvements to performance have been my top priority. In some cases, performance is improved more than 10x compared to OpenShot 2.1. Adding huge images to your timeline is now fully optimized, and won’t slow you down. Editing HD videos (5K, 4K, 2.5K, and 1080p) is vastly improved. A new caching engine was built from the ground up, and supports both memory and disk back-ends, depending on the user’s needs. This can be configured in the Preferences, under “Cache”. Also, opening huge projects (with hundreds of files / clips) has been optimized and is up to 10x faster.

Improved Stability
Many critical bugs have been fixed related to seeking, missing frame detection, and AVPacket scope, which results in a much more stable engine, especially on slower systems. Also, compatibility has been improved for Linux AppImage and OS X (10.9+) App Bundles.

Keyframe Enhancements
Keyframes are used in the animation system in OpenShot, and have received some major upgrades. Support for CSS syntax (quadratic bezier curves) now allows a %-based approach to setting the curve handles. This is very useful, and better than the previously hard-coded values. Also, 28 curve presets have been added for common things like ease-in/out, bounce, etc… Many other improvements have been made to Keyframes, such as better undo/redo support when dragging property values (in the property editor), rendering color keyframes on the timeline, and improved frame detection when using the property editor (i.e. adding a keyframe for the currently selected frame).

Error Handling / Reporting
Our library (libopenshot) and Python UI (openshot-qt) have improved error handling, and can now detect stack-traces for crashes and exceptions (on Linux, Mac, and Windows). Not only can it pull out the stack-trace, but it can send that anonymously to the OpenShot website back-end, so I can quickly identify where crashes are happening and more quickly fix them. In other words, OpenShot 2.2 now has real-time error reporting, which I’m really excited about. This can be disabled in the preferences, along with metric reporting. It also contains no personal information, just a basic stack trace of what function crashed.


New Title Templates
Many Kickstarter backers requested new title templates to be added to OpenShot. I am proud to announce that all new titles are now included in OpenShot 2.2. We have some really nice additions, such as Film Ratings, TV Ratings (small corner rating), and more!

Infrastructure Improvements
One of the most challenging aspects of running an open-source project such as OpenShot, is the large amounts of data (downloads, installers, etc…). We had been using Amazon S3 previously, and our monthly costs skyrocketed to over $1000 just for data transfer. So, we’ve moved our installers into GitHub (which ironically happens to also be powered by S3), and our installer-related data transfer costs have gone to $0! So, a huge thanks to GitHub for being awesome!

We have also integrated torrents into our build server, and all major releases now include torrents (on our download page), to help further distribute our data transfer.

Misc / Bug Fixes
Many other bugs have been fixed, and lots of small improvements that defy categorization are listed below.
Selection handles (in progress)
Ability to disable unit tests (useful for distros that have a broken unittest++ library)
Broken Ubuntu 16.10 PPA fixed
Fixed bug when opening .OSP projects via command line
Disabled SSL validation (not used anyway)
Fixed bug when opening legacy 1.4.x project files that contain UTF-8 encoded characters
Preferences now save settings on close of dialog (and persist even if a crash follows)
Added FileVersion and custom icon to Windows installer (more polished)
Ability to drop a file directly on the timeline (without dropping it in your Project Files first)
Fixed bug where the tutorial does not find the correct widget
Began work on a new help manual using sphinx (not quite ready yet)
New 2.5k and 4k profiles added
Fixed margins on OS X and Windows around QDockWidgets
Fixed bug when switching between Thumbnail and Detail views
Alpha backgrounds have been fixed on all Blender animated titles
Recently opened menu logic has been fixed
Translations updated for 70+ languages

OpenShot 2.1 Released!

I am proud to announce the release of OpenShot 2.1, which contains a huge number of new features, bug fixes, and improvements! Enjoy the release video, which by the way, was created with OpenShot 2.1 (of course)!


Animation Demo
OpenShot supports many important animation features, such as support for transparent image sequences, powerful keyframe support, and multiple layers. When combined properly, you can create some very stunning animations! In July, I attended Texas Linux Fest in Austin, TX with my 16 year old daughter, Madeline, who happens to be a very talented artist. She created an animation (using OpenShot) LIVE during the expo, while attendees watched and threw out suggestions and ideas. Take a look at her final animation (which we also debuted during my presentation towards the end of the show)!

You can check out more of her work @ DeviantArt.

Features & Improvements
Many stability and performance related improvements have been made, including multiple memory leak fixes, but we also found time to add some really fun and highly requested features, such as...

Audio Waveform Support
OpenShot now supports the ability to display audio waveforms on clips, swap audio channels, as well as separating audio into another clip (or multiple clips - one per channel). This opens up lots of interesting flows, such as adjusting the volume of individual audio channels, removing certain channels, or easily fixing audio drift.

Improved Property Editing
Editing advanced properties has never been easier! Simply drag your mouse on the sliders to change the value and automatically set a keyframe. The sliders keep your adjustments within a reasonable range. Right click on any value to change the interpolation mode or remove keyframes. As you move the playhead over the clip, the sliders will also move, revealing the animation values at that particular time. Green indicates a keyframe. Blue indicates a calculated frame. The icon indicates the interpolation mode.

New Selection Dropdown
A new selection dropdown has been added above the property editor. It displays the name of the current selected item (clip / transitions / effect), and allows the user to quickly switch the property editor to another item. It also displays the thumbnail of each item, as well as any nested effects. This is especially useful when there are multiple overlapping items, and it’s difficult to select the correct one by pointing and clicking the mouse.

User-Configurable Keyboard Mappings
Users now have the ability to see all keyboard shortcuts used by OpenShot, and even customize them. This also fixes some issues with Ubuntu and a long-standing bug preventing certain shortcuts from working with their unified menu bar. In addition, we’ve added new shortcuts for some common things like, Select All/None, Copy/Paste, etc...

Windows 64-bit Support
We have invested a ton of time on the Windows version of OpenShot, especially the dependencies (Qt, FFmpeg, Python 3), and I'm happy to report it works great now. We also changed the installer, and upgraded everything to 64-bit (which means no more 32-bit support for the moment).

Timeline Improvements
When initially dragging a file or transition onto the timeline, the user will now get full snapping support. This was actually pretty difficult, since adding a new item to the timeline is a much different flow than simply moving an item already on the timeline. We also added the ability to lock a track, preventing any dragging or resizing. Playback of the timeline now stops at the final clip on the timeline... instead of just playing black frames. New context menus have been added for alignment, slicing, and more. And finally, added a new track menu button, and updated some styles on the timeline.

New Tutorial System
When a user first launches OpenShot, a new tutorial system pops up some friendly messages instructing them how everything works. It can be dismissed with a single click (to prevent power-users from getting annoyed), but my hope is that is makes OpenShot much more welcoming for new users, and especially users with limited knowledge of video editing.

Slice All @ Playhead
I've extended the slice feature to work across all tracks, by right clicking on the playhead icon. You can use this to quickly slice all clips and transitions at the exact same spot, and keep the left side, right side, or both sides. And by using the new Keyboard shortcuts, this can also be done without using a mouse.

Huge Performance Gains with Effects
While we still have a few bottle necks on performance we plan on addressing soon, we targeted the very slowest parts of libopenshot and made some dramatic improvements in speed, especially on the following filters: brightness & saturation. These filters can be animated over time, creating some really cool effects.

Misc Improvements
Custom Profile Support
Improved 1.x Project Support
Improved Translations (fixed many spots that were not being correctly translated)
Improved Debug Support (in the Preferences you can enable debug mode, which dramatically slows down everything, but creates some great debug log files in the /.openshot_qt/ folder)

Bug Fixes
Fixed a regression on the Split Video screen
Fixed Animated Title screen regression
Long timelines now supported (up to 48 hours). This was actually a pretty nasty bug, which was causing issues on any project with more than 1 hour of video.
Memory Leaks - The largest leaks have now been plugged
And lots of minor bug fixes

OpenShot 2.0.7 - Beta 4 Released!

I am proud to announce the 4th beta release of OpenShot 2.0! As you will see, lots of great progress has been made since the previous beta. Improved stability, especially for OS X and Windows, better performance, new features, and critical improvements to the OpenShot infrastructure (build servers, website, etc…). Download OpenShot 2.0.7 (Beta 4)
Improved Compatibility & Stability
There were 2 really big issues with the previous beta releases: some Mac computers could not launch OpenShot due to incompatibilities between the CPU and certain libraries (compiled with brew), and random crashes with Windows during preview/playback. Both of these issues have been fixed, and a big thanks for all the testers who helped me with each experimental revision. I could write an entire update on these 2 points alone, they both took a huge amount of time to troubleshoot, and are reasonably well documented on Github.

Image Sequences
General support for image sequences has been added in Beta 4. Just drop a single file from a sequence (i.e. 001.jpg, 002.jpg, 003.jpg, etc...) into the project files, and it will now prompt you to import the file as an image sequence. Doing so will create a single clip, and basically treat the sequence of images as a video file.

File Properties
Added a new file properties dialog, which displays all known video/audio details about a file. It also allows the name, tags, and frame start/end to be modified for a file. And, for files without an audio track, it allows the frame rate to be adjusted (useful for animations / image sequences).

Build Server (Daily Builds)
One of the biggest challenges for testers and myself is to speed up the cycle from bug fix to testable release. While some users compile everything manually, and some Linux users get updates delivered through our PPA, Windows, Mac, and certain Linux users must wait for me to create a new installer (which takes lots of time). So, I have built a cross-platform build server (i.e. really just a cool Python script which is scheduled to run every few hours). It checks Git for updates, re-compiles libraries, freezes the OpenShot Python 3 application (along with dependencies), signs the Windows / Mac versions, and uploads the files to Amazon S3, and lists these files on the openshot.org website. I currently have 3 build servers running (Windows 10, OS X 10.11, Ubuntu 14.04) and creating builds automatically.

To see the list of recent builds for your operating system, just click the “Other Downloads” link on www.openshot.org/download:

Legacy 1.x Project Support

Initial support for opening legacy 1.x OpenShot project files has been added. It currently supports: Files, Tracks, Clips, and Transitions, with some properties being imported (such as animated fade in/out support, volume fade in/out support, transition up/down support). Works well for most basic 1.x projects. As needed, I’ll revisit this logic, and probably add some additional support as users request it.

Faster Timeline Performance
Updated AngularJS from v1.2.16 to v1.2.29. I'm seeing much faster performance with animation and dragging / dropping on the timeline. At some point, we'll probably move to the latest version of AngularJS, but that will likely break a few things, which is why I'm holding off for now.

Universal Linux Version
I’m very excited to debut a new Linux version of OpenShot 2.0, using the AppImage format. This format uses a single file to download, mark as executable, and then launch. All needed dependencies are included in this file, and it does not need to be “installed”. This is similar to the Mac DMG approach, and works with the latest version of Arch, Debian, Fedora, Gentoo, openSUSE, Ubuntu (and probably more, but I've actually tested those).

Improved Project Saving
Added more error logging and exception handling around saving projects, and added additional try/catch blocks around making paths relative, making paths absolute, and moving temp files. Basically, it can error on those methods, log the errors, but the project will still be saved successfully.

ImageMagick Support Optional
ImageMagick support is now an optional dependency, which is great news for those who would like to compile OpenShot on Windows. This was by far the most difficult dependency to deal with on Windows, and the most difficult dependency to ship with OS X. So, it has been removed from the Mac and Windows versions of OpenShot, and made optional for anyone wanting to compile things themselves.

Updated Translations
All translations have been updated, and I’ve personally tested more than 50 languages, fixing errors such as missing string formatting tokens, etc… A huge thanks to all the contributors that have helped improve the translations. It still amazes me to watch OpenShot transform into another language. So cool!

Misc Bugs Fixed:
Missing Quit menu on OS X
Fullscreen menu / toolbar issues
Windows path bug for animated titles
Switch to thumbnail view bug
Missing cancel prompt when exiting application
Incorrect translation credits URL
Additional error handling when loading fonts
Invalid zoom slider value when loading a project
Python and Ruby bindings are now optional in libopenshot
Improved seeking with image sequences and animations

OpenShot 2.0.6 (Beta 3) Released!

Greetings Everyone! I am proud to release the third beta of OpenShot 2.0 (full details below). This marks the 3rd full release of OpenShot 2.0 in the past 30 days. I am working closely with testers and users to address the most critical issues as they are identified.

Installers and Downloads
If you are interested in trying out OpenShot 2.0, you are in luck! For the first time ever, we are releasing the beta installers to everyone, so feel free to grab a copy and check it out!
Windows: Version 2.0.6 MSI Installer
Mac: Version 2.0.6 DMG
Linux: Install our Daily PPA (for Ubuntu and related distros). Other distros now support OpenShot 2.0 as well, including Debian, Arch, and Gentoo.

Smoother Animation
Animations are now silky smooth because of improved anti-aliasing support in the libopenshot compositing engine. Zooming, panning, and rotation all benefit from this change.

Audio Quality Improvements
Audio support in this new version is vastly superior to previous versions. Popping, crackling, and other related audio issues have been fixed.

Autosave
A new autosave engine has been built for OpenShot 2.0, and it’s fast, simple to configure, and will automatically save your project at a specific interval (if it needs saving). Check the Preferences to be sure it’s enabled (it will default to enabled for new users).

Automatic Backup and Recovery
Along with our new autosave engine, a new automatic backup and recovery feature has also been integrated into the autosave flow. If your project is not yet saved… have no fear, the autosave engine will make a backup of your unsaved project (as often as autosave is configured for), and if OpenShot crashes, it will recover your most recent backup on launch.

Project File Improvements
Many improvements have been made to project file handling, including relative paths for built-in transitions and improvements to temp files being copied to project folders (i.e. animated titles). Projects should be completely portable now, between different versions of OpenShot and on different Operating Systems. This was a key design goal of OpenShot 2.0, and it works really well now.

Improved Exception Handling
Integration between libopenshot (our video editing library) and openshot-qt (our PyQt5 user interface) has been improved. Exceptions generated by libopenshot are now passed to the user interface, and no longer crash the application. Users are now presented with a friendly error message with some details of what happened. Of course, there is still the occasional “hard crash” which kills everything, but many, many crashes will now be avoided, and users more informed on what has happened.

Preferences Improvements
There are more preferences available now (audio preview settings - sample rate, channel layout, debug mode, etc…), including a new feature to prompt users when the application will “require a restart” for an option to take effect.

Improved Stability on Windows
A couple of pretty nasty bugs were fixed for Windows, although in theory they should have crashed on other platforms as well. But for whatever reason, certain types of crashes relating to threading only seem to happen on Windows, and many of those are now fixed.

New Version Detection
OpenShot will now check the most recent released version on launch (from the openshot.org website) and descretely prompt the user by showing an icon in the top right of the main window. This has been a requested feature for a really long time, and it’s finally here. It will also quietly give up if no Internet connection is available, and it runs in a separate thread, so it doesn’t slow down anything.

Metrics and Anonymous Error Reporting
A new anonymous metric and error reporting module has been added to OpenShot. It can be enabled / disabled in the Preferences, and it will occasionally send out anonymous metrics and error reports, which will help me identify where crashes are happening. It’s very basic data, such as “WEBM encoding error - Windows 8, version 2.0.6, libopenshot-version: 0.1.0”, and all IP addresses are anonymized, but will be critical to help improve OpenShot over time.

Improved Precision when Dragging
Dragging multiple clips around the timeline has been improved. There were many small issues that would sometimes occur, such as extra spacing being added between clips, or transitions being slightly out of place. These issues have been fixed, and moving multiple clips now works very well.

Debug Mode
In the preferences, one of the new options is “Debug Mode”, which outputs a ton of extra info into the logs. This might only work on Linux at the moment, because it requires the capturing of standard output, which is blocked in the Windows and Mac versions (due to cx_Freeze). I hope to enable this feature for all OSes soon, or at least to provide a “Debug” version for Windows and Mac, that would also pop open a terminal/command prompt with the standard output visible.

Updated Translations
Updates to 78 supported languages have been made. A huge thanks to the translators who have been hard at work helping with OpenShot translations. There are over 1000 phrases which require translation, and seeing OpenShot run so seamlessly in different languages is just awesome! I love it!

Lots of Bug fixes
In addition to all the above improvements and fixes, here are many other smaller bugs and issues that have been addressed in this version.
Prompt before overwriting a video on export
Fixed regression while previewing videos (causing playhead to hop around)
Default export format set to MP4 (regardless of language)
Fixed regression with Cutting / Split video dialog
Fixed Undo / Redo bug with new project
Backspace key now deletes clips (useful with certain keyboards and laptop keyboards)
Fixed bug on Animated Title dialog not updating progress while rendering
Added multi-line and unicode support to Animated Titles
Improved launcher to use distutils entry_points
Renaming launcher to openshot-qt
Improved Mac build scripts (version # parsing)
Fixed many issues with keyboard shortcuts
Known Issues
WebM export crash on Windows
DVD export crash on some versions of Linux
Some translation issues with certain languages. Please review your language translations here.
Some users have reported issues launching OpenShot on Mac
Some stability issues with Windows - still haven’t nailed down the cause… but it’s probably related to threading and a couple more race conditions that only seem to happen on Windows.

It's About Time! OpenShot 1.2.2 Released!

I am proud to announce the immediate availability of OpenShot version 1.2.2! We have been hard at work on this version since April 2010. While a 5 month long release cycle was not really what I had planned on, I'm happy to see this version finally get released!

Round of Applause
Before I give you a run down of the new features, I want to take a moment to thank all the great and talented people who stay up late with me working on this project. Andy Finch has been helping me since the very first days of OpenShot, and without his help, OpenShot would probably not be here today. Olivier Girard is one of the biggest promoters of OpenShot, writing articles, assisting new users, and was the primary contributor to the awesome OpenShot help manual. Maël Lavault has been a huge help on LaunchPad, answering questions, submitting patches, and was a huge help on this latest version. To all the people who have helped me, THANK YOU SO MUCH for making OpenShot the great application it is today!

Getting Started
Now, let's talk a bit about version 1.2.2. Where did 1.2.0 & 1.2.1 go? Why did we skip straight to 1.2.2. Well my friends, that is an interesting story, but one for another day. Just know that 1.2.2 is the official release, and it's awesome! I might be a little biased, but seriously, this is a really great release.

Video Highlights
As is tradition, I have used OpenShot to create a short video showcasing some of the new features. I mixed in some great overly dramatic music, and a few screen-casts to create a true masterpiece. Okay, I admit, the video is not quite a masterpiece, but if I said that, nobody would watch it.

OpenShot 1.2 Highlights from Jonathan Thomas on Vimeo.
New Features:

* Improved Stability
* 3D Animated Titles (powered by Blender 2.5)
* Custom Transitions
* New Audio & Video Effects
* Time-line Improvements / Animations
* Improved Effects User Interface
* Improved Theme Engine (New netbook friendly theme)
* Razor Improvements (now supports snapping to play-head)
* Improved Language Support (Rotate effect now works in all locales)
* New DVD Export (Create compliant DVD images)
* Improved Preferences Dialog
* Improved Exporting of different frame-rates
* Numerous Bug Fixes

Let me dive into more depth on a few of these new features, and provide some screen-shots for your viewing pleasure.

3D Animated Titles
We have taken the power of Blender, some really cool animated title templates, and mixed them together with the simple and user-friendly style of OpenShot to create a truly unique feature. Everyone can now enjoy creating their own animated title sequences! Of course, none of this would be possible without the great Blender open-source 3D animation package! Colin Levy, the director of Sintel, even contributed a slick title animation to OpenShot! Blender has so many good features, but most are difficult for the average user to tap into. I hope that we can expand this relationship even further in future releases.

New Audio & Video Effects
Many new effects have been added to this release. However, a few effects had to be removed, due to crashes and instability on some systems. We replaced the missing effects with even cooler ones, so no tears. My favorite new effect is called Chroma Hold. This effect turns your video into grayscale except for 1 color. I've seen this effect used on TV commercials many times, and now we can all use it!

Timeline Improvements & Animations
We have added lots of polish and some subtle animations to all clip and transition movement, which is easier for the eye to follow. For example, clips that are not placed in a valid spot, smoothly (but quickly) animate back to their correct location. Clips that are removed animate into a dot and disappear. Same for transitions.

[click for larger image]

Improved Theme Engine (Netbook friendly theme)
The code that draws the time-line and buttons (our theme engine) has been drastically improved. Now theme artists can not only change the images, but the height, width, offset, position, alpha, and color of items. In theory, almost any video editor interface can now be created... assuming some artists want to jump in and help out. Also, a new theme was designed for netbook screens, taking advantage of the new theme engine.

[click for larger image]

GTK 2.18 Required
Okay, so what does this mean? In Ubuntu terminology, you must have Ubuntu 9.10 or greater to run this version of OpenShot. The glade library (which we previously used to display our interface) has been depreciated, and so we moved onto just using the GTK library. Many of the GTK features we are now using only work on GTK 2.18+, so with the assumption that most users are on 9.10 of Ubuntu (or greater), we decided it was not worth the effort to back-port to previous version of Ubuntu. However, it is possible (in theory) to adapt OpenShot to Ubuntu 9.04, but that's about as far back as possible, without recompiling GTK... and who wants to do that. =)

Download Today
The OpenShot PPA is the easiest way to install (and stay updated). It works on Ubuntu 9.10 and greater. Just follow the easy instructions, and enjoy! However, if you would rather download the DEB installers, you can do that as well.

Fun Fact
Did you know that in Kerala, India, a high-school textbook is including a chapter on OpenShot to be taught at all the schools in their city? How cool is that!

Conclusion
Thanks again to all the blog readers, users, supporters, translators, programmers, artists, directors, packagers, donors, and of course to my wife, Cindy, who allows me the time to work on this project.


Version 1.1 Released!

It seems like just yesterday we released version 1.0 of OpenShot. However, two months have passed, and we have a brand new version just busting at the seams with excitement and anticipation. I am proud to announce the immediate availability of OpenShot 1.1!

40 different bugs and features have been addressed in this version, including some highly requested features such as Undo/Redo support! As tradition, here is a video I put together announcing 1.1. All of the footage was filmed on my Canon HF S100, and edited with OpenShot (of course).

OpenShot 1.1.0 Released! from Jonathan Thomas on Vimeo.

Here are the highlights:

* Speed, speed, and more speed improvements. Over 1300% faster rendering previews after an edit. 1000% faster launching OpenShot. Seriously though... it's way faster.
* Undo / redo (with history panel)
* Improved export screen. Only your installed formats and codecs are listed. Improved notifications after the export has finished (using libnotify). One of the most common crashes of OpenShot was selecting an export format that was not installed. So this should provide much more stability.
* Multiple copies of effects can be added to clips. A common scenario would be using 2 chroma key effects, each with a different shade of green or blue.
* Dynamic tiling of overlapping clips (Brady Bunch style). This can take an unlimited number of clips (that are all on separate tracks playing at the same time), and tile them across the screen. OpenShot does all of the math, and the user only has to click 1 menu option (in the Layout menu). Just imagine the possibilities.
* New effects have been added: Contrast, Edge Glow, Saturation, and Cartoon.
* Fade in / out menu has been added. This is the quickest and easiest way to dissolve / fade a clip (including audio).
* Edit titles with ease. Use our simple title editor or Inkscape. Just right click on a title, and select "Edit Title". Also, when you duplicate a title, it will now create a new SVG and add it to your project.
* New keyboard shortcut to cut / slice clips. Just press the "c" key, and it will cut clips at the position of the play-head (i.e. the red line).
* Improved localization and translations. Many labels, buttons, and tool-tips were missing from our translation system. Also, numbers on the export screen (such as bit rate) would not work in other languages. These have been fixed, and OpenShot works much better in other languages.
* Timeline scrolling has been improved to better support lots and lots of tracks. The left and right side of the timeline will always stay in sync now.
* H.264 support has been improved to support Debian


OpenShot 1.0 Has Arrived!

Here is a quick rundown of the new features:

* Transition snapping - Transitions now snap to the nearest clip or the play-head.
* Improved Stability - Just try and crash OpenShot now. We dare you. Seriously though, many common issues that would crash OpenShot have been resolved, and the overall stability is great now.
* Improved Accuracy - The accuracy of our edits and cuts has been improved. No more skipped frames, out of place frames, or flashes of white.
* New Transitions - 28 new transitions have been added.
* New Titles - 29 new titles have been added (both in 4:3 and 16:9 ratios). Also, titles are higher quality, and look great up to 1080p. Based on your project's aspect ratio, the Title Editor will automatically show you the correct aspect ratio titles. In other words... no more squished or stretched titles.
* New Themes - Two new themes have been added, making a total of 4 themes. A) simple theme with smaller icons for small screens. B) flat blue theme - a theme with no glass or gloss.
* Time Format Improved - The time format has been changed to include the frame number, instead of the millisecond:
* New Profile - HDV 720p 24 fps
* More Languages - There are now 42 languages included with OpenShot version 1.0!
* Help Manual Integrated - The help manual is now integrated, and will launch in your native language (assuming we have a translation for that language). Currently, French, Spanish, and English are 100% translated.
* User Interface Enhancements - Many small changes to the UI have been made to simplify OpenShot. The "Open Project" toolbar button has been replaced by the "New Project" button. This removes the confusion between importing files and opening files. A few other buttons, labels, and icons have been changed also.
* Window State Fixed - The window state now correctly recognizes "maximized", and is more reliable. In other words, when you resize the window, vertical panes, or horizontal panes in OpenShot, it remembers your screen layout the next time you launch it.
* Clip Properties Fixed - The IN and OUT properties have been fixed to not allow the user to overlap them. The "Add Effect" button has been fixed to work correctly with audio effects.
* Chroma Key Fixed - Some users were unable to see the color picker on the chroma key effect. This has been fixed.
* Tooltips Translated - The main screen has been improved to show translated tooltips on all of the toolbars.
* Lock File Fixed - The lock file now verifies that it is valid, instead of preventing OpenShot from launching.

Actually - waste of time. Random crashes. Can't export - crashes again.
Not recommended to even try it.


Review by dani on Dec 1, 2019 Version: 2.4.4 OS: Windows 10 64-bit Ease of use: 5/10 Functionality: 1/10 Value for money: 1/10 Overall: 1/10




I like the idea and the look of it, but in use the interface is clunky and counter-instinctive, e.g. it is very fiddly trying to find a particular frame to mark and then cut. The audio is not visible by default and it is very slow to scan a clip to show it. On a fast PC with lots of RAM it should fly smoothly, but it doesn't. It can open off-air HD h.264 TS files, but it stutters and locks up frequently when editing them.

Having used much older versions of the program which crashed every few minutes, I was impressed when I edited and exported a video with no problems in about ten minutes

I then tried to make a slide show using around 30 jpg photos and a music track but after trying to fiddle with transitions, the program froze completely. I couldn't close it and didn't know about killw at that stage so I restarted the computer.

When I restarted I tried to open Openshot but it flashed instantly and then closed each time. I thought if I removed my project source files it would be ok, but now while I can open the program I am in a permanent loop demanding I find the directory for the files, but with no 'cancel' option or ability to access the main menu and start a new project. I downloaded the daily update to see if this might make a difference but that is no different.

I am not sure what to do next as somewhere the AppImage file has made start up files but despite lots of searches in system files I cannot find these.

A shame. It looks nice, just crashs randomly. Sometimes on opening, sometimes importing projects, sometimes playing video in preview, it just randomly crashs whenever. I hope they can get this up soon because it looks to be really nice to use. At the very least, take this version down and put up a version that works.
