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.
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.
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!
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…
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.
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.
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).
This version makes a big change to the way project files are saved. Now, they
always save numeric values using a period for the decimal point regardless of
your OS locale (region/language) setting. This makes it possible to collaborate
with others that have a different decimal point setting without going through a
(probably incomplete) repair process. This should also help to avoid bugs. This
change applies to new projects only; old projects load and run same as before
including saving. However, be aware that if your locale does not use a period
for the decimal point, then older versions of Shotcut will try to repair a
project created with this version because the older versions do not have this
Timeline and Keyframes Rulers
We changed the Timeline and Keyframes rulers interval to 5 seconds and
show only HH:MM:SS and no frame units. This makes them cleaner and quicker to
Reorganized Some Video Filters
Renamed video filter Circular Frame to Crop: Circle.
Renamed video filter Crop to Crop: Source.
Renamed video filter Text to Text: Simple.
Renamed video filter 3D Text to Text: 3D.
Renamed video filter Overlay HTML to Text: HTML.
Renamed video filter Blur to Blur: Box.
Renamed Reduce Noise video filter to Reduce Noise: Smart Blur.
Changed Export > From to show Source instead of base file name.
Changed the default for Settings > Display Method back to DirectX on
Changed maximum duration of Color, Text, and Color Bars clips to
Increased maximum value of the Timer filter’s Start Delay,
Duration, and Offset parameters to 24 hours.
Improved Export Job progress and estimated time remaining.
In the previous versions of Shotcut the Blur video filter could create dark
edges on the image. Therefore, 3 new blur filters were added that do not
have this problem:
Blur: Exponential (fast)
Blur: Low Pass (fast)
Blur: Gaussian (slow)
However, they do not support Keyframes or support blurring in only a horizontal
or vertical direction. So, the existing blur filter was retained but renamed
The previous version changed the appearance of the toolbar to address a high
density (DPI) issue on Linux. However, that made the icons larger for most
people. Also, some people would simply hide the main toolbar since it took up
so much space. Now, there are two new options in the View menu:
Show Text Under Icons (default on)
Show Small Icons (default off)
Added Jobs to the main toolbar.
Reordered panel buttons on main toolbar to match View menu.
Alpha Channel Support for HTML-based Filters
Shotcut can use HTML technologies for video effects, but previously it was
limited at support the existing image or video’s alpha channel (transparency
mask) and would always overwrite it with its own alpha channel, which often
times was opaque. For example, this prevented maintaining transparency when
using 3D text on a transparent color clip. Now, it supports the alpha channel.
Using this, we have new Crop video filters.
Previous versions of Shotcut’s Crop filter did not behave as some expected
because it removes pixels from the edges of the source and thus changes its
aspect ratio. Still, it can be useful when working with sources with a
higher resolution than the project because it does not require one to crop and
then upscale to remove black bars. Therefore, the existing crop filter was
renamed to Crop: Source, and two new crop filters were added using HTML.
These two new crop filters can use the HTML alpha channel support by changing
the alpha component of their Color parameter. This is very useful when using
Crop: Rectangle or Crop: Circle while compositing video tracks.

The main announcement for this release is a major update to an important library
that Shotcut uses for the UI (user interface) called Qt.
There have 6 major releases and two LTS (long term support) releases since the
version we were using. The new version we are using is Qt 5.9.7, which is
LTS (5.9) and is quite stable given the number of revisions (.7). It is a little
faster as well. We did not upgrade to the latest LTS (5.12) in order to retain
compatibility with macOS 10.10 and 10.11, and we want to use the same Qt version
across platforms. (Linux Flatpak is an exception.) With our new Qt builds, we
added support for HTTPS, which extends to our HTML effects based on WebVfx
and QtWebKit. This will let custom HTML titles and effects that you make link
Added Offset to the Timer video filter.
Added Vertical HD 30 fps and Vertical HD 60 fps video modes.
Shotcut is a free, open source, cross-platform video editor for Windows, Mac and Linux. Major features include support for a wide range of formats; no import required meaning native timeline editing; Blackmagic Design support for input and preview monitoring; and resolution support to 4k.
