v19.08.16

This version continues to rework and refine existing features in the areas of video stabilization, audio normalization, converting and reversing files, external monitoring, and most significantly: the playlist.

Playlist

Changed Playlist > Open As Clip to simply Open. This action now opens the playlist item directly in the Source player, and all changes made in Source (trim in/out), Properties, Filters, and Keyframes apply to the playlist item immediately without an explicit update.
Added Playlist > Copy that opens a copy of the playlist item in Source just like the old behavior. This is useful if you want to trim out another shot from the same source clip or create a different sub-clip with different filtering.
Changed double-click on a playlist item to Open the clip instead of Copy it.
Added keyboard shortcut Shift+C to Copy a playlist item.
Now, when you drag a clip from Playlist to Timeline the timeline shows an appropriately-size box on a track.
Filters

Fixed a performance regression (since v19.06) in the following filters: Chroma Hold, Flip, LUT 3D, Mirror, Noise: Fast, Reduce Noise: Smart Blur.
Fixed reloading the filter UI for Rutt-Etra-Izer, Text: 3D, and Text: HTML resets the filter trimming in Keyframes.
Added support for keyframes to the Lens Correction and Mosaic video filters.
Fixed Swirl when maximum = 0%.
Changed the minimum values for Mosaic to 0%.
Removed the scrolling animation from the Blank Web Animations HTML template.
Fixed pasting filters changes the trim and keyframes of the existing filters.
Fixed Crop: Circle and Crop: Rectangle not clearing the canvas resulting in trails in some situations.
Fixed color incorrect when using the LUT 3D filter with some other filters following it.
Fixed reliability of the Stabilize video filter to write its results (.stab) file.
Fixed showing vidstab.trf as a missing file.
Fixed updating Stabilize and Normalize: Two Pass results to clips copied between Source, Playlist, and Timeline.
Added the ability for the Stabilize and Normalize: Two Pass filters' analysis jobs to update pending export jobs.
Added the option to run pending Stabilize and Normalize: Two Pass filters' analysis jobs on export. This only works for Stabilize if you are using the project folder feature. Or, if not using the project folder feature, you must click Analyze to assign a results file name, but you can stop the analysis job.
The combination of the above fixes and changes means you can now easily batch convert files while applying image stabilization and audio normalization!

Properties

Added support for interlace output to Properties > Reverse and Convert to Edit-friendly including overrides for Scan mode and field order.
Improved detection of interlaced video in some files such as Ut Video in Matroska.
Added Comments to image properties along with a menu button with: Copy Full File Path, Show in Folder, and Set Creation Time...
External Monitor

Add resolution and refresh rates to the screens in Settings > External Monitor to make them easier to differentiate.
Fixed switching between different external screens on the same GPU.
Fixed external screen not showing on correct screen in some arrangements.
Export

Changed the default video quality to 55% for the Default and YouTube presets. This aligns with the x264 default crf of 23 and produces a smaller file that most people desire for upload without significant quality loss.
Added text after Export > Advanced > Codec > Quality to show the generated codec-specific quality level (e.g. crf for x264).
Fixed Stream broken by check for writable file.
Other

Fixed double-click in Recent Projects loading twice.
Fixed disabling meters in the Audio Loudness scope not shrinking space.
Added version metadata to the AppImage for Linux.
Added md5sums.txt and sha256sums.txt to the GitHub releases page.
Added saving Timeline track height to configuration, not only a project file.
Fixed trimming an unselected clip in Timeline does not correctly adjust its filters.
Changed Settings > Interpolation > Nearest Neighbor to no longer relax seek accuracy. Instead, seek accuracy is now relaxed only during trick playback (reverse, rewind, fast forward).
Added a Korean translation.

New Features

Added View > Scopes > Video Histogram
Added Preset to some more filters:
Audio Gain/Volume
Blur
Brightness
Opacity
Added Preset and simple and advanced keyframes to the Balance and Pan audio filters.
Added a Levels video filter with simple and advanced keyframes!
Added Properties > Color Range for video clips.
Replace the Mask video filter with 3 new filters:
Mask: Simple Shape
Mask: From File
Mask: Apply
The new Mask: Apply filter makes it possible to mask filters without using multiple tracks! Use Mask: Simple Shape or Mask: From File to start the filter mask followed the video filters to be masked followed by Mask: Apply to apply the mask to the filters in between. Filters before or after the mask filters affect the entire video frame. One can still use Mask: Simple Shape or Mask: From File to affect the alpha channel for multitrack compositing as before. This makes them compatible with existing information and tutorials that suggest using multiple tracks as well as enabling collage/montage or transition effects when the tracks do not use the same clip.

The new Mask: From File is a powerful new video filter offering 3 modes:

wipe transition (stock or custom)
Channel > Brightness from a video or image file (File > Custom...)
Channel > Alpha from a video or image file
Moreover, Threshold can be animated with simple or keyframes, which is especially nice when used with luma-wipe image files (stock or custom). Not only can you wipe on a masked filter but also you can use this as an alternative way to make a wipe transition using multiple tracks (instead of same track transition).

incompatible license.

Windows build, since more memory can be accessed now, we have removed some of
(not all) multi-threading limits.

Stay away from version 2019.09 Beta if you are exporting to x265. The videos do not play well in many devices. I didn't have the same issue with version 2019.08.16.

Review by gkotse on Sep 7, 2019 Version: 19.09 Beta OS: Windows 10 64-bit Ease of use: 5/10 Functionality: 3/10 Value for money: 10/10 Overall: 6/10




Linux version (appimage) does not run on Debian 8 (Jessie) as claimed on the developer's site (at least not on mine). It depends on GLIBCXX 3.4.21 which isn't supported by Debian 8.

Probably one of the most stable open-source video editors out there for Windows.

However, Kdenlive has more features than ShotCut. However, ShotCut has better cross-platform support with binaries for Windows.
