Kdenlive 19.08 released
by farid a. | Aug 16, 2019 | News, Releases | 0 comments

After a well deserved summer break, the Kdenlive community is happy to announce the first major release after the code refactoring. This version comes with a big amount of fixes and nifty new features which will lay the groundwork for the 3 point editing system planned for this cycle. The Project Bin received improvements to the icon view mode and new features were added like the ability to seek while hovering over clips with the mouse cursor and now it is possible to add a whole folder hierarchy. On the usability front the a menu option was added to reset the Kdenlive config file and now you can search for effects from all tabs instead of only the selected tab. Head to our download page for AppImage and Windows packages.

3 point editing with keyboard shortcuts

With 19.08.0 we added groundwork for full editing with keyboard shortcuts. This will speed up the edit work and you can do editing steps which are not possible or not as quick and easy with the mouse. Working with keyboard shortcuts in 19.08 is different as in the former Kdenlive versions. Mouse operations have not changed and working as before.

3 important points to understand the new concept:

Source (left image):
On the left of the track head the green vertical lines (V1 or A2). The green line is connected to the source clip in the project bin. Only when a clip is selected in the project bin the green line show up depending of the type of the clip (A/V clip, picture/title/color clip, audio clip).

Target (right image):
In the track head the target V1 or A1 is active when it’s yellow. An active target track react to edit operations like insert a clip even if the source is not active (see “Example of advanced edit” here).

The concept is like thinking of connectors:
Connect the source (the clip in the project bin) to a target (a track in the timeline). Only when both connectors on the same track are switched on the clip “flow” from the project bin to the timeline. Be aware: Active target tracks without connected source react on edit operations.

You can find a more detailed introduction in our Toolbox section here.

Adjust AV clips independently with Shift + resize to resize only audio or video part of a clip. Meta + Move in timeline allows to move the audio or video part to another track independently.

Press shift while hovering over clips in the Project Bin to seek through them.

Adjust the speed of a clip by pressing CTRL + dragging a clip in the timeline.

Now you can choose the number of channels and sample rates in the audio capture settings.

Other features

Added a parameter for steps that allows users to control the separation between keyframes generated by the motion tracker.
Re-enable transcode clip functionality.
Added a screen selection in the screen grab widget.
Add option to sort audio tracks in reverse order.
Default fade duration is now configurable from Kdenlive Settings > Misc.

Renderwidget: Use max number of threads in render.
More UI components are translatable.

Kdenlive 19.04 released
by farid a. | Apr 22, 2019 | Releases | 0 comments

We are happy and proud to announce the release of Kdenlive 19.04 refactored edition concluding a 3 year cycle in which more than 60% of the code base was changed with +144,000 lines of code added and +74,000 lines of code removed. This is our biggest release ever bringing new features, improved stability, greater speed and last but not least maintainability (making it easier to fix bugs and add new features).

New refactored timeline

Split Audio/Video
We have changed the way timeline tracks work. Each track is now either audio or video, and will only accept audio and video clips respectively. When dragging an AV clip from the project bin in timeline, the clip will be automatically split, the video part going on a video track, and the audio part on an audio track.

Configurable layout
Tracks can be individually resized. (Holding down shift makes all video or audio tracks change in height simultaneously.)

Switch live between two different layout modes (Mixed or Split).

Keyboard Navigation
You now have the possibility to move clips and compositions with your keyboard. To do it, select a clip in timeline and use the “Grab Current Item” (Shift+G) function from the Timeline menu.

You can then move the item with your arrow keys. Keyframes can also be moved individually. Just click on a keyframe in timeline, then move it left/right with arrows, change its value with + and -. Alt+arrow to go to another keyframe.

Improved keyframe handling
Add a new keyframe by double clicking in timeline.
You can move a keyframe without altering it’s value by using the vertical line that appears when you are above or below a keyframe.
Remove a keyframe by dragging it far above or below the clip limits.

Audio Recording
An option in track headers allows you to have audio record controls. This enables you to play your project while recording a voice over comment. Very handy for making tutorials. (Not available in the AppImage version yet.)

Other improvements
Configurable thumbnails for each track. You can choose to display between In frame, In/Out frames, All frames or No thumbnails.
Improved workflow due to keyboard shortcuts and track targets.
Added group hierarchy (group of groups).
You can now copy/paste timeline clips between different projects (if you have 2 running instances of Kdenlive or after opening a different project) using the standard copy/paste.
Clip name always displayed when scrolling.
Individual clips can now be disabled while still in the timeline but with no audio and no video – (works for all clip types)
Faster timeline preview with support for hardware accelerated encoding.
Improved feedback on move/resize.
Automatic timeline color switch when changing the color theme.
When using the Razor tool (x), you can now press shift while moving the mouse cursor over a clip to preview the cut frame.

Project Bin
Improve management of proxy clips (can now be deleted for each clip).
Shortcut icon to drag only the audio or only the video of a clip in timeline.
Improved management of audio/video streams, also allowing to enable/disable audio or video for a clip.

Monitor toolbar: move with the mouse to the upper right corner of the monitor to access the toolbar.
Support multiple guide overlays.
Shortcut icon in clip monitor to drag only the audio or only the video of a clip in timeline.
Support for external monitor display using Blackmagic Design decklink cards.

Effects and Compositions
Major improvements to the Speed effect.
Added back the Motion Tracker. (For compiled MLT versions with OpenCV support only.)
You can now define preferred effects and compositions. These will appear in the timeline context menus and in the effect/composition baskets for easier access.
Organized effects under 3 categories, “Main” (which contains the most important audio/video effects), “Video effects” and “Audio effects”.
Tested and removed all effects which are not working.
When dragging a composition from the list into timeline, it will automatically adjust its duration (to fit the entire clip or the duration of a clip overlap depending on the context).
Move the whole Rotoscoping mask at once. Moving all points in the mask: A cross is displayed at the center of all points that allows moving the whole mask.
1 click transitions

Added configurable visual guides.
Visualize missing elements, allowing to move or delete them.
A combobox allows you to choose the default background, between checkered, black and white.
Align buttons now cycle to allow you to align to safe margins and frame border instead of just frame border.

Added support for HW accelerated render profiles. (Experimental)
Added support to render with a transparent background for export formats that support alpha channel. (Experimental)

Since a long time, Kdenlive allowed users to download extra user contributed resources from the KDE Store. These download options have now been moved to more logical places instead of the “Settings” menu. Title templates can be downloaded from the Titler dialog, Render profiles from the Render dialog, Luma compositions from the Composition list and Shortcut layouts from the Shortcuts dialog.

There is still work to be done! We concentrated on stability (finding and fixing as many crashes as possible) and that the most important functionality for a slim editing workflow works. There are still known issues in which we will dedicate the next 3 monthly releases of the 19.04 cycle to finish polishing the rough edges.

So why release? Well, this version is much better than the old one. Having it out in the wild will help us test it under various situations. We now have a stable platform allowing us to fix issues quicker in order to move on to adding new features.

18.12.1 released
by farid a. | Jan 10, 2019 | News, Releases | 0 comments

The first dot release of the 18.12 series is out with fixes and usability improvements. The most exiting change is the fix for audio capture when recording from screen or webcam, a handy feature for people doing video tutorials.

You can now import keyframes to your effects and use them in other projects. On the usability front the “Gain” effect is now in the correct “Audio correction” category and theming issues in the AppImage are now fixed. Speaking of AppImage, we now have a fully automated build system ready so devs can focus on coding gain.

Don’t forget to check our nightly refactoring branch version which received many fixes during the holidays and is ready for another round of testing.

Kdenlive 18.08.3 released
Kdenlive 18.08.3 is out with updated build scripts as well as some compilation fixes. All work is focused on the refactoring branch so nothing major in this release. On the other hand in the Windows front some major breakthroughs were made like the fix of the play/pause lag as well as the ability to build Kdenlive directly from Windows. The next milestone is to kill the running process on exit making Kdenlive almost as stable as the Linux version.

In other news, we are organizing a bug squash day on the first days of December. If you are interested in participating this is a great opportunity since we have prepared a list of low hanging bugs to fix. See you!

Kdenlive 18.08.2 released
by farid | Oct 12, 2018 | News, Releases | 1 comment

Kdenlive 18.08.2 is out bringing usability improvements and a crash fix. The Windows version is also becoming more stable with every release and this version brings fixes to the translation installation and the introduction of a crash report.

In other news, the Refactoring is moving steadily ahead and we will release a wider test beta version soon, stay tuned. Also the refactoring branch is now building automatically on KDE’s automated integration system (CI), and all the regressions tests pass. This means that after each change to the source code, the CI will run the tests to check that no regression happens. On the sysadmin front we are cleaning up our bug tracker in preparation for the 18.12 release.

Bug fixes:

Improve missing luma detection (region transition) – fixes project crash. Commit.
Home/End now also seek in clip monitor. Commit.
Update AppData for upcoming release. Commit.
Windows crash reports. Commit.
Update authors. Commit.
Fix double clicking a title clip in bin tries to rename instead of opening the title dialog. Commit.

18.08 Beta
Kdenlive: test the future
by Jean-Baptiste Mardelle | Jul 4, 2018 | News | 0 comments

After more than 1.5 years of work, we are planning to release the refactoring version of Kdenlive in august, part of the KDE 18.08 Applications release. But taking such a decision is not easy. Most of the code was rewritten, which also means many possible regressions. So while we are very excited to have the opportunity to finally release our work to the public, it’s also a bit stressful. So what now ?

Well that’s where we need you. The latest refactoring code has been published as an AppImage, and we need some feedback. So you can help us by downloading the latest AppImage, and try it on your computer (just download the file, make it executable through your file manager and run it).

Improvements and new features include:

Clips with video and audio are now automatically separated when dropped in timeline
All clip types in timeline can now easily be disabled/enabled
Slowmotion should work reliably
The long standing issue where moving groups of clips corrupted timeline should be gone
Most effects now use a common keyframe interface
Insert/lift/overwrite should work reliably
Easily share your rendered video through KDE’s Purpose library (YouTube, NextCloud, Twitter, Kde connect,…) requires a recent KF5 environment, not enabled on the AppImage.
It is now possible to generate lower resolution clips for the timeline preview to have a faster rendering
Resizable track height
Several overlay guides available for each monitor
New keyboard layouts can be installed in 1 click (we need help to create interesting layouts)
And most importantly, the code is now much cleaner and ready for new features.

You should be able to create new projects, add clips, move them in the timeline, add effects and compositions, and render your projects. But there are still a number of known issues that we are working on:

Compatibility with older kdenlive project files is not perfect
The curves effect does not work (Bézier curves works)
Composition settings don’t update on resize
A performance issue in audio thumbnails causes major slowdowns on high zoom levels
Some feedback on this beta version would be really appreciated. So please help us, test this AppImage version and let us know what you think of it. You can leave comments in this post, or on our mailing list, and we will soon organize a bug squashing day to make this release as reliable as possible!

So we hope to hear from you soon!

Kdenlive 18.04.1 released
by Jean-Baptiste Mardelle | May 11, 2018 | News, Releases, Uncategorized | 0 comments

While our team is working on the awaited refactoring, we still managed to add 2 small usability improvements in the 18.04.1. version. First the safe zone overlay was improved so you can now easily spot the center of your frame:

Then we improved the default background color for the titler so that white text can easily be read without having to make further adjustments.

These changes were made during our great Paris sprint. At the same time, we are improving our packaging efforts, so you can find the following download options right now (besides official distro packages):

AppImage: the latest 18.04.1 version is available, now with support for Ladspa plugins
Flatpak: we are glad to announce the availability of Kdenlive on flathub, so it can now easily be installed on distributions supporting flatpak (thanks to Peter Eszlari).
Windows: Vincent Pinon worked on an update to the Windows version, so windows users can now test the latest 18.04.1.

Kdenlive 18.04


Kdenlive 17.12.0 released
by Jean-Baptiste Mardelle | Dec 15, 2017 | News, Releases | 0 comments

Kdenlive 17.12.0 released
We are happy to announce the latest Kdenlive version, part of the KDE Applications 17.12 release, making it the last major release using the current code base. This is a maintenance release focused on stability, while feature development is going in next year’s 18.04 version. Proxy clips were given some attention and should give you better seeking experience as well as reduced memory usage for images. Other fixes include fixes in timeline preview, a crash when using a Library clip and smoother seeking on rewind playback.

We have been pushing the AppImage packages lately because it allow us to put all required dependencies inside one file that can easily be downloaded and run on all linux distros. Today, we can also announce the immediate availability of the Kdenlive 17.12 AppImage, downloadable here :

AppImage related fixes:

Fix audio distortion affecting the 17.08.3 AppImage
Include Breeze style
Vincent Pinon is also continuing the support for the Windows version, and you can get Kdenlive 17.12 for Windows here:

We are also making available the first usable “preview” AppImage of the refactoring branch which will receive all development focus from now and will be released as 18.04. It is not ready for production but allows you to have a look at Kdenlive’s future. You may follow the development progress here.

Kdenlive 18.04 alpha 2 release:

Meet us:
Next Kdenlive Café is tonight on #kdenlive at 21PM (CET), so feel free to join us for some feedback!

Packagers must take note that libsamplerate is now a dependency due to recent changes in FFMPEG.
It is recommended for Ubuntu (and derivatives) users to use the AppImage version until further notice.

Kdenlive 16.12.1 released with Windows version
We are proud to announce the first maintenance release for the 16.12 cycle. Besides the usual bugfixes and usability improvements this release also marks the official release of the Windows port.
Windows port
Last summer, thanks to a Google Summer of Code slot, Joseph Joshua started to work on a Windows port of Kdenlive. Vincent Pinon then continued to work on it and we are excited to offer today the much expected first version of Kdenlive for Windows. This is a first testing version, zipped in a folder that does not require an install. You must however separately install FFmpeg, following the simple instructions provided on the download page.
Packaging effort is also going on the Linux side, with an up to date Appimage and *Ubuntu PPA containing the latest release, so you have no excuse not to try Kdenlive.
You can go straight to our download page to get the instructions to install Kdenlive 16.12.1
About Kdenlive
Kdenlive is an open source video editing software, based on the MLT framework and FFmpeg libraries. We are a small team and are always welcoming new contributors.
We hold a monthly IRC Kdenlive café where users and developers meet, and you can also exchange on our forum or on our mailing list. Some great tutorials are also available from the toolbox section of our website.
We are part of the KDE community, which provides, among other, all the infrastructure for Kdenlive.

Kdenlive 16.12 released
by farid | Dec 15, 2016 | News, Releases | 2 comments

The 16.12 release cycle brings the much requested Rotoscoping effect back and new effects, Library improvements, OGG render profile, UI fixes and as with every release much more stability.
This release marks the first step towards implementing Advanced Trimming Tools which will be introduced in 17.04. For that to happen we are starting a refactoring of the timeline making this feature easier to implement and preventing/fixing corruption issues.
If you want to support our work, please consider donating to KDE’s End of Year 2016 Fundraiser! (KDE provides some core libraries, all infrastructure and much more making Kdenlive possible).
Here are some of the highlights of the 16.12 release:
Allow custom cache folder. You can now define a custom folder per project to store temporary files. This can be useful if you want to store temporary files on another drive, and also if you want to easily move your project’s temporary files to another computer
Portable projects: to allow moving a project to another computer / drive, we now use relative paths for clips that are inside the project’s directory. So if your source clips are in the same folder as your kdenlive project file (or in subfolders), you can simply move/copy the directory and the project should open without any change.
When you (re) use the same image sequence clip, title clip, or even color clip multiple times in the same libary clip, such image sequences and titles will only be added once to your project bin. (See also our Toolbox post on Library Clips with Image Sequences, Titles, and Color Clips.)
The way Kdenlive expands library clips containing multiple tracks should be more intuitively now: place the library clip on the topmost track, it will be expanded down from there if multiple tracks are required. If there aren’t enough tracks below, yet enough tracks when taking also above tracks into account, then Kdenlive will make use of the above tracks too. Kdenlive now correctly expands clips immediately below a transition, instead of reporting an error. Error reporting has been improved in general for expanding library clips. (See also our Toolbox post on Copy & Paste Between Projects.)
Rotoscoping effect
Added a UI for LUT3D effect
Added tripod parameter to vidstab
Improved motion tracker
Added OGG render profile
User interface
Download render profiles, wipes and title templates directly from the interface.
Added a context menu option to directly extract single frames to the project bin. See also our Toolbox post Extract Frame to Project for more details and instructions.
Added new configuration option for automatically raising the properties pane when selecting certain timeline elements (Toolbox post with details and instructions).

Kdenlive 16.08.0 is here
Aug 18, 2016 | News | 18 comments

Kdenlive 16.08.0 is here
Kdenlive 16.08.0 marks a milestone in the project’s history bringing it a step closer to becoming a full-fledged professional tool. The highlights of this release are:
3 Point Editing
Insert or overwrite a timeline region with a clip region.
Delete or lift timeline regions.
Also, the long-missing insert mode is now enabled and fully functional: simply drop clips onto the timeline and existing clips will move accordingly to make room.
Timeline effect rendering
Sometimes, you just have too much effects or transitions in your timeline to be able to play it in realtime (you can see on the video, it can only play 13 frames per seconds). This is where this new feature helps you: it pre-renders parts of the timeline so that they can be played in realtime. And you can continue working on other parts of the timeline while Kdenlive is working in the background for you.
Stability and Improvements
Over 370 bug fixes and code commits including various improvements to:
DVD Wizard
Timeline refactoring
User interface
Audio mixing
Faster keyboard workflow
New icons
New profiles
Fix memleaks and corruptions
Profile Selection UI
For a full list of changes please visit the full log page.
Library Widget
The new Library Widget allows to copy and paste sequences between different projects.
Track header visual optimization
Ability to control the width of the track header by dragging its right border left or right.
Track compositing preview
Individual track control has been replaced by a global option in timeline toolbar to switch compositing modes between: High Quality, Preview and None.
Start-up wizard removal
Kdenlive’s start-up wizard is now removed and will appear only if a configuration problem is detected. Kdenlive now starts up picking the best default options (including NTSC/PAL framerate depending on your region).
Cached Data Manager
Kdenlive as a video editor can produce large amounts of temporary data. Until now, all these temporary files were saved in $HOME/kdenlive. We are now switching to an XDG compliant scheme, and try to give users more infos about how much data is stored, and allow for easy mangement.
Krita support
Native support for Krita images was added.
New Logo and Website
A new modern logo and website reflecting the new phase of the project.

We also celebrate this development cycle with an increased amount of community participation.
In other news more work has been done porting Kdenlive to Windows as part of a GSOC project. Also work has started by the Macports team to bring it to OSX.
Stay tuned for more information on what the future holds.

Kdenlive 16.04.1 information page

Kdenlive 16.04.1 was released on the 10th of May 2016.

"Split view " to display a split view of timeline's current clip with and without effect to compare
Speed effect now uses MLT's new TimeWarp producer, so sound is now working with speed effect
Support for curves in some effect parameters (volume, etc)
Project Bin

Metadata: clip metadata is back, giving you details about your audio / picture files
Improved automatic profile: if enabled, Kdenlive automatically proposes to switch profile to match that of the first added clip
Generators: you can easily create noise, color bar and counter clips

New Library widget allowing to save parts of the current timeline to share them between several projects

Kdenlive 15.12.2 and 15.12.3 are minor bugfix releases, and were released in february and march 2016. Among the changes, Kdenlive will now automatically use the Breeze widget style if available when used on a non KDE Desktop. Several timeline corruption issues were also fixed.

Kdenlive 15.12.1 released

Submitted by j-b-m on Thu, 01/14/2016 - 15:58
The latest release of Kdenlive brings many bugfixes to the 15.12.0 version. More than 20 issues were fixed and we encourage all users to upgrade. You can find more details about the fixed issues in our information page.

Kdenlive 15.12 knocking on the door... test it easily before release!
Submitted by vpinon on Tue, 12/01/2015 - 23:48

We've had much work on 15.8 series, with its 3 monthly bugfix to repair the breaks from the new monitor backend & timeline rewrite... should be acceptable now :)
For few weeks now we're having fun integrating few new features, inspired from our usability review, that should make users' life easier?

Kdenlive 15.08.0 was released with KDE Applications 15.08.0 on 19th of August 2015.

This is a major release containing many changes to the core source, in an effort to cleanup the code.

Major changes

New file format. Kdenlive can open older project files, but older Kdenlive versions cannot open the new file format.
Drop SDL support for monitor display, we now use OpenGL - should be supported on all fairly recent computers.
Improved UI for color correction effects (Sop/Sat)
It is now possible to add an effect to a Bin clip by dropping the effect on the clip. The effect will then be applied to all instances of this clip in timeline, mostly useful for color correction
Effect Preview: Clip monitor now has an option to "Compare effect" displaying a customizable split screen to see the clip with and without effect
Missing features

Due to the large refactoring, several features have been disabled, but we hope to re-introduce them as soon as possible. These are:
Clip generators disabled (countdown, noise, online content search)
Blackmagic Decklink playback / capture disabled
Stopmotion Widget disabled
Check if clips are on a removable device
Rotoscoping effect broken
Fixed issues

[Bug 350250] (Solved) Title clip: Created Title-Text-Image not visible in Clip- nor Project-Monitor (black Field, no Text)
Updated on Wednesday August 05, 2015

[Bug 350275] About window in 15.04.3 still refers to the old bugtracker
Updated on Tuesday August 04, 2015

Kdenlive 15.04.0 released
Submitted by j-b-m on Thu, 04/16/2015 - 19:58

The Kdenlive team is happy to announce the release of Kdenlive 15.04.0. While there are very few new features in this release, it is a huge step towards a bright future!

Kdenlive is now an official KDE application
This has several implications:

We fully benefit from KDE's infrastructure, which means less worries for the developpers.
We stick to KDE Applications release schedule, which means one bugfix release every month, one feature improved version every 4 months. That's a big change from the previous random release every year or so. This is possible because the KDE team takes care of the release, not our small dev team, so a big thank you to KDE.
We now use KDE's bugtacker at
We benefit from KDE's build servers and team, which means that we might in the future have Mac OS and Windows versions without too much efforts from the dev team.
We can now be part of the Google Summer Of Code.
We have adopted the KDE Applications numbering scheme. From now on, Kdenlive versions will be numbered with Year.Month.Bugfix. That explains the 15.04.0 version.
Every KDE contributor can help us improve Kdenlive.
What changes right now for Kdenlive users
Most of the work for this release was porting the code to Qt5 and KDE Frameworks 5 (KF5). While users will not see direct benefit, this makes us ready for the next big steps. Changes in this version include:

Since we are now based on Qt5/KF5, you NEED KDE Frameworks 5 to run Kdenlive.
Fixed video stabilization
Auto save new projects
Download new render profile feature fixed
You can download the source code, binary packages for your distro should hopefully be prepared by distibution packagers.

What will change in the near future
While Kdenlive 15.04.0 is mostly a Qt5/KF5 port, we have many new features/improvements in preparation for the 15.08.0 release. Here are some of the features that we are currently working on:

Finally integrate some of Till Theato's work resulting from our Indiegogo campain. It took us 2.5 years but we are finally merging parts of the refactoring effort.
Use OpenGL for the video display, bringing back experimental GPU display and effects
Add effects to Project clips: for example, add color correction to the clip in the Project Bin. Every instance of the clip that is then used in timeline will have that color correction.
Cleaning the code to make it easier to understand.
That's it for today, I probably forgot many things but that might be an excuse to blog more often :).

Kdenlive 0.9.6 released

We are happy to announce the immediate release of Kdenlive 0.9.6.

This version fixes several bugs and crashes, including a very annoying bug that caused project files to seem corrupted. All users are strongly encouraged to upgrade.

You will find detailled infos about the changes in this release on our Kdenlive 0.9.6 info page.

Kdenlive 0.9.4 was released on the 28th of January 2013.

This is a bugfix and stability release with several improvements.
Some highlights:

Rewritten DVD Wizard
The DVD Wizard was mostly rewritten, now allowing 16:9 menus. It now also autodetects the format of your videos and proposes a trandcoding if it is necessary. In fact, you can now drop any video in the Wizard and just click transcode to get it in the correct DVD format.

DVD menus were also broken in the past versions, this should be fixed. While the menu creation remains very basic, you can now add a shadow to the menu's texts to make them look nicer.

Improved clip markers
The clip markers (comments that can be added and used for seeking in the clip) have been improved. You can now have several categories that show up in different colors. Markers can also now be imported and exported, and are compatible with Audacity's format.

Rewritten Screen Capture
In previous versions, screen capture was performed through the RecordMyDesktop utility. This caused several troubles since it created Ogg Theory files that were not correctly supported by MLT (seeking issues). So in this release, the Screen Capture feature now relies on FFmpeg / Libav which means one less dependency and a more reliable capture. Encoding parameters can be adjusted by the user.
Support for multiple streams clips
Some apps, like video chat application can produce video clips that have several streams embedded, for example where you can see and hear each participant to a conversation. Kdenlive now detects this kind of clips and allows you to import them as separate clips so that you can use the different streams.
Clip analysis feature
An exciting new feature is also introduced in this version: clip analysis. In short, we can have some MLT effects that analyse the clip and store the result for further use. The first usable cases are:
automatic scene detection: Kdenlive can now parse your clips to find the different scenes and add markers or cut the clip accordingly. The process is currently very slow but it's a start.
Improved motion tracking: Kdenlive can also now analyse an object's motion, and the result of this can be used as keyframes for a transition or an effect. For example, you can now have a title clip that follows an object.

Stability and Performance improvements
Lots of efforts were put into stability and performance, seeking in timeline shoud be smoother, you now have audio scrubbing when using OpenGL display, audio can be recorded while playing your project for voiceover effects, and much much more.

I have to give this a big fat fail! It won't open in macOS Mojave. It probably has an unmet dependency, but if that's the case, the Mac install package should either install them, or come with a readme.txt that instructs the user on what dependencies are needed and how to install them... I used to really like this package in Ubuntu Linux.

The best open source non-linear video editor.
It works better on linux, but it's understandable, I think it's a KDE program ported in Windows not long time ago.

Just because you don't know what an appimage is and don't know how to "install" or "uninstall" portable software on Windows, that doesn't mean there is something wrong with the program and should be rated with 1.
It's just your lack of knowledge, in fact you should be rated with 1 as a user, not Kdenlive as a program.
