New in Shotcut 24.02.29 (Mar 7, 2024)

Ambisonic Audio:
Ambisonic spatial (spherical) audio is often used with 360° video whether output as spherical or reframed to a rectangle. Adding support for Ambisonic facilitates 360° video workflows with Shotcut.
But also the new Ambisonic Decoder audio filter is part of an affordable, simple way to record (e.g. GoPro MAX, Zoom H3-VR) Ambisonic audio and convert it to 5.1 surround. FYI, YouTube supports 5.1 surround on most TV-oriented devices (smart TVs, streaming boxes, game consoles). And Windows has something called Sonic to listen to surround through headphones. The new filter can also be used to listen to Ambisonic through headphones (binaural), to rotate the sound when you rotate spherical video, and to pan stereo or surround audio output for reframed 360° video.
Added Settings > Audio Channels > 4 (quad/Ambisonics).
Added Ambisonic Decoder audio filter that converts to binaural, stereo, quad, Ambisonic, or 5.1 surround. When Ambisonic mode is chosen, it is an Ambisonic panner.
Added Ambisonic metadata to Set Equirectangular if there is a track with 4 audio channels.
Added Copy Parameters to 360 video filters to use with Ambisonic Decoder > Paste Parameters.
Shotcut only supports first order Ambisonics at this time.
More New Stuff:
Added support for AMD AV1 hardware encoder on Windows (av1_amf) and Linux (av1_vaapi).
Added automatic vertical scrolling to Timeline when moving a track.
Added changing Properties > Duration on image clips on the Timeline (behavior depends on Ripple similar to changing Properties > Speed on an audio/video clip).
Fixes and Changes:
Upgraded macOS and Windows to Qt version 6.5.3, which changes the mininum macOS version to 11.
Stop automatically grouping audio/video clips when Detach Audio (changed in v24.01).
Improved selection in Timeline after various operations.
Improved behavior changing Properties > Speed with Timeline > Ripple on.
Improved the speed of opening a timeline project.
Fixed Filters > + > Sets adds audio filters in reverse order (broke in v24.01).

NEW STUFF:
Added Player > Loop () and Player > Set Loop Range to the menu and player controls.
Added Timeline > Selection > Group/Ungroup (Ctrl+G, command+G on macOS).
This is basically a saved multi-selection system. So, the operations it supports are all those available for multiple selection. That does not include trim, Filters, or Properties at this time.
Added support for multiple selection to Split At Playhead.
Added Timeline > Edit > Split All Tracks At Playhead (Shift+S).
Added Edit > Undo and Redo support for adding, removing, changing, and disabling Filters.
Added Timeline > Edit > Nudge Forward (.) and Nudge Backward (,).
Added Pause and Resume to the context menu in Jobs.
Added Settings > Backup with options for:
Manually
Hourly
Daily (default)
Weekly
This creates a backup of the current project file in a manner similar to File > Backup and Save except it is automatic now unless Manually is chosen.
Added File > Other Versions submenu that tries to find similarly-named project files in the same folder create by Shotcut backup or recovery mechanisms.
Added Settings > Player > Audio API on Linux and Windows.
Basically, this makes the --SDL_AUDIODRIVER command line option available in the Settings menu.
Added a Previous button to View > Application Log dialog that goes to the log file created by the previous app session.
Now, on startup, Shotcut makes a backup of shotcut-log.txt to shotcut-log.bak.
Added a Copy button to all text viewer dialogs that does the same thing that the non-obvious Select All and Copy actions in the context menu.

New in Shotcut 23.12.15 (Dec 17, 2023)

New in Shotcut 23.11.29 (Dec 2, 2023)

This highlight of this version is the addition of easing for keyframes: ease in, ease out, and ease in/out with different levels of acceleration and tricks like elastic and bounce. See the Easing Functions Cheat Sheet web page for an animated graphical overview of these behavior options.
IMPROVEMENTS:
Added Crop:Rectangle > Apply to Source button.
This button is only enabled when the aspect ratio of the source media matches your project's Video Mode because it is impossible to include the black padding that Shotcut adds to a source. This feature is the primary way to simply "crop a video." You do not need to use the timeline for this. You can simply:
set Settings > Video Mode to Automatic, open a video file,
add the Crop: Rectangle video filter, adjust the rectangle control in the player, click Apply to Source in the Filters panel, choose Yes in the dialog asking to change the Video Mode, and Export.
Added Opacity to GPS Text, Text: Simple, and Timer filters.
Improved performance of Timeline > Zoom.
Added rectangular selection to Timeline.
Added Settings > Timeline > Rectangle Select.
This is on by default, and scrubbing with the mouse on the timeline requires clicking near the play head.
When this is on, hold Shift to turn it off temporarily. When this is off, hold Shift to temporarily turn it on.
Changed the Smooth keyframe type to avoid overshoots and cusps.
This only applies to new projects made with this and future versions. Thus, the behavior of smooth keyframes made with an earlier version remains the same for compatibility reasons.
Added Ease In, Ease Out, and Ease In/Out to Keyframes.
This also changes the appearance of keyframes in the timeline view of Keyframes to make it more clear where the behavior applies - between keyframes. Remember this: when thinking about "in" or "out", for Shotcut "in" refers to the beginning of something - a clip, filter, or parameter between keyframes. And "out" refers to the end of something. So, this is not easing into a keyframe and easing out of a keyframe. Rather, it is easing into or out of the change/segment/span/tween of a parameter between keyframes.
Added Properties > View Bitrate....
If you have ever used the classic Bitrate Viewer for Windows and frustrated with the lack of updates or not available on your current OS, here you go.
Added a Track Auto Fade Video filter. This can only be added to tracks and makes a dip to black or other color or fade in and out opacity for overlays to each clip.
Changed Export > Codec and Audio to disable some options when a lossless-only or an intra-only codec is selected.
Added Settings > Timeline > Automatically Add Tracks.
The defaults for this is off because adding tracks increases memory usage. Also, it does not automatically add a track if nothing is in the Timeline as the timeline is optional in Shotcut. Also, it does not automatically add a track when you open a project with no empty tracks. It only adds tracks when you add something to the timeline or move a clip between tracks.
Added a button in Filters to save a filter set and change the Copy checked filters button to not show a dialog.
Added Filters > Set > Glow Intensity.
This demonstrates how you can mix a filtered output with the input to reduce it.
Also, change the Mask: From File > Treshold to do a side-by-side comparison with and without the filter.
Added Split at Playhead back into the timeline clip context menu.
Changed the Save option in the low memory dialog to perform a backup and save to prevent breaking projects.
Added support for av1_nvenc NVIDIA AV1 hardware encoder on Windows and Linux.
Upgraded MLT to version 7.22.0.
NEW BUGS:
Fixed honoring the "Do not show this anymore" checkbox in the Convert to Edit-friendly dialog (configuration key showConvertClipDialog) (broke in v23.09).
Fixed the new batch convert dialog (View > Resources) appeared instead of the old Convert to Edit-friendly one when dragging a single concerning clip to Playlist or Timeline (broke in v23.09).
Fixed Motion Tracker filters are forgotten upon switching to Source player (broke in v23.09).
Fixed Mask: Simple Shape > Softness not working on macOS (broke in v23.05).
Fixed saving a favorite for Filters > + > Sets.
Fixed Timeline appears all white on Qt 6.6.
Fixed libvpx security vulnerability CVE-2023-5217.
Fixed libwebp security vulnerability CVE-2023-4863.
OLD BUGS:
Fixed Text: Simple > #createdate# keyword deletes preceding text.
Fixed a crash when opening View > Scopes > Audio Loudness.
Fixed marker at start of the next clip was deleted when using Timeline > Edit > Ripple Trim Clip Out.
Fixed Properties > Transition changes were lost when Undo after trimming a clip's out point on the Timeline.
Fixed a crash when Undo after trimming a transition that resulted in a new transition.
With this fix Shotcut no longer permits creating a new transition within the same mouse drag that removes a transition.
Fixed AMD (AMF) quality options in a saved Export preset shows up in the Other tab overriding Codec > Quality.
Fixed YouTube export preset is not H.264 high profile with some hardware encoders.
Fixed a memory leak when using YADIF deinterlacers.
Fixed color of export from still images when using full range and pix_fmt=yuv444p.

New in Shotcut 23.09.02 Beta (Sep 3, 2023)

New in Shotcut 23.07.09 (Aug 1, 2023)

NEW BUGS:
Fixed crash on startup on older Windows 10 computers that do not have Direct3D 11 (broke in v23.05).
Fixed Timeline scrubbing and skimming accelerate too much (broke in v23.06).
Fixed Stabilize analysis jobs not working on a speed-adjusted timeline clip (broke in v23.05).
Fixed the visibility of the cursor in the Text: Rich filter's editor (broke in v23.05).
Fixed the up and down cursor keys not working in some numeric fields (broke in v23.05).
Fixed seeking on the new Speed: Forward Only and Speed: Forward & Reverse filters.
Fixed the buttons in the Delete Filter Set confirm dialog are hidden if the name is long.
Fixed the color level of RGB and RGBA sources (e.g. images) with GPU Effects.
Fixed crash adding a GPU filter to Timeline > Output by not showing GPU filters for that selection.
OLD BUGS:
Fixed shift-drag-drop from Windows Explorer to Playlist deletes the files! This is an old bug, and Shotcut is not deleting the files. But it accepts a move drop action for the purpose of reordering playlist items. However, doing so with a list of filenames makes Windows assume the receiving application did something appropriate with thes file and then... delete them on behalf of the app just to be sure?!? Smooth move. (Another Windows file manager Directory Opus does not exhibit this bad behavior.)
Fixed another very old bug on Windows where sound does not follow the default output device, for example plugging headphones, until you restart the app. Please note that if you are using Settings > Audio Channels > 6 (5.1) after the default sound output changes, you will likely experience distortion in the audio playback until you restart the app.
Added the --SDL_AUDIODRIVER command line option for Windows and Linux.
Fixed appending to Playlist from clipboard with nothing yet opened in the Source player.
Fixed the Export > Audio > Quality range for the aac codec.
Fixed trying to drag a keyframe vertically may snap changing its horizontal position.
Fixed clicking OK in a color dialog on Windows without changing anything resets the alpha to 255.
Fixed top-field-first interlaced output.
IMPROVEMENTS:
Added Track Auto Fade and Track Seam audio filters. These filters address an old problem where clicks and pops may be heard in export when switching between clips due to discontinuities in the audio stream. A recommended technique was to add a 2 frame Fade Audio Out and Fade Audio in filters on clips. Track Auto Fade automates that. Track Seam works on a similar level but rather attempts to do a smoothing between outgoing and incoming samples around edit points. Both of these new filters may ONLY be added to individual tracks—audio or video.
Added Transition type > Cut to the Slideshow Generator.
Added Ctrl+Wheel (command on macOS) to numeric fields to increment and decrement by a larger amount.
Updated Qt libraries to version 6.4.3.
Updated libebur128 to version 1.2.6.
Updated rubberband library to version 3.2.1.
Updated MLT to version 7.18.0.

Fixed another very old bug on Windows where sound does not follow the default output device, for example plugging headphones, until you restart the app. Please note that if you are using Settings > Audio Channels > 6 (5.1), after the default sound output changes, you will likely experience distortion in the audio playback until you restart the app.
Added the --SDL_AUDIODRIVER command line option for Windows and Linux.
Fixed Timeline scrubbing and skimming accelerate too much (broke in v23.06).
Fixed Stabilize analysis jobs not working on a speed-adjusted timeline clip (broke in v23.05).
Fixed the visibility of the cursor in the Text: Rich filter's editor (broke in v23.05).
Fixed the up and down cursor keys not working in some numeric fields (broke in v23.05).
Fixed seeking on the new Speed: Forward Only and Speed: Forward & Reverse filters.
Fixed appending to Playlist from clipboard with nothing yet opened in the Source player.
Fixed UI in macOS shows white blocks on startup.
Fixed the Export > Audio > Quality range for the aac codec.
Updated Qt libraries to version 6.4.3.
Updated libebur128 to version 1.2.6.
Updated rubberband library to version 3.2.1.

New in Shotcut 23.07.09 Pre (Jul 10, 2023)

This version continues to fix recent regressions as well as address some long standing known problems.
Added Track Auto Fade and Track Seam audio filters. These filters address an old problem where clicks and pops may be heard in export when switching between clips due to discontinuities in the audio stream. A recommended technique was to add a 2 frame Fade Audio Out and Fade Audio in filters on clips. Track Auto Fade automates that. Track Seam works on a similar level but rather attempts to do a smoothing between outgoing and incoming samples around edit points. Both of these new filters may ONLY be added to individual tracks—audio or video.
Fixed shift-drag-drop from Windows Explorer to Playlist deletes the files! This is an old bug, and Shotcut is not deleting the files. But it accepts a move drop action for the purpose of reordering playlist items. However, doing so with a list of filenames makes Windows assume the receiving application did something appropriate with thes file and then... delete them on behalf of the app just to be sure?!? Smooth move. (Another Windows file manager Directory Opus does not exhibit this bad behavior.)

New in Shotcut 23.05.07 Pre (May 8, 2023)

New in Shotcut 23.04.20 Pre (Apr 23, 2023)

Qt 6:
Qt is the main UI and app library (separate from the media engine) that Shotcut uses. This is the first major upgrade of it since Shotcut started over 10 years ago with Qt 5! (Some interim upgrades did feel major tho.) It was a lot of work, but as a result:
The Windows version now directly uses Direct3D 11 instead of OpenGL (or OpenGL converted to Direct3D) for drawing portions of the UI: Timeline, Keyframes, Filters, and the video player. This is faster, and we hope it improves compatibility.
The Windows version improves support for fractional display scaling in the system settings (e.g. 125% or 150%).
The macOS version now directly uses Metal (Apple's GPU tech) instead of OpenGL for drawing portions of the UI (see above). It is faster.
The macOS app is now universal: compatible with both Intel and Apple Silicon CPUs (M1/M2) in the same app.
Some fixes for commonly reported Linux bugs like some images not rendering, visual controls not showing, and OpenSSL 3 compatibility. This also ought to improve things on Wayland.
There is now an ARM64 build of the Flatpak for Linux (but none of the core developers currently has a Linux/ARM system for testing and support).
Performance Improvements:
Besides the performance improvements from Qt 6 above:
Some timeline optimization.
Additional multi-threading in audio/video file reading.
Faster preview for most video clips without filters.
GPU Effects:
Settings > GPU Effects is back! We made several big fixes to improve its stability. Decoupling it from the OpenGL used for the UI and video display also helps. This is being made for testing purposes to get feedback before deciding whether to leave it on in the April release. If you think its performance is not so great try it with Preview Scaling. GPU effects' performance improvement mainly comes on systems with weak CPUs, with certain filters like Scale & Position, and when stacking filters and video tracks. It also works best when using only GPU filters.
GPU effects is not just about performance but also quality since it does all processing in linear color, which gives optimally colored blending and interpolation.
End-to-end support for 10-bit! For this to work, on 10-bit sources use only GPU filters. Nothing prevents you from adding CPU filters, but that will introduce an 8-bit down- and up-conversion into the pipeline. To add text, use a text clip using Open Other > Text as that is not a 10-bit video source.
Searching in Filters on "gpu" shows only/all GPU filters.
All previous limitations are removed and working now: text filters, video scopes, stabilization.
The Blend Mode video filter and track Properties option is not available because it is not yet implemented.
Rotation is not available in the Size & Position filter because that is not implemented yet.
Motion Tracker Filter:
Added a Motion Tracker video filter. This is required to use motion tracking. It only does the preview and analysis and is not intended to include effects but rather drive other video filters...
Added a Load Keyframes from Motion Tracker button to the following filters:
Corner Pin
Crop: Rectangle
GPS Text
Mask: Simple Shape
Size, Position & Rotate
Size & Position (GPU)
Spot Remover
Text: Rich
Text: Simple
Timer
The Motion Tracker can be on a different clip than the clip with the above filters.
The dialog only shows Motion Trackers that have successfully completed analysis.
Click Reset in the dialog to remove the keyframes added by motion tracker and restore the state of these parameters to before motion tracking.
Clicking Apply in the dialog more than once automatically resets the affected parameters before adding new keyframes; so, you do not need to reset manually between changes.
You can edit the added keyframes, but if you reapply the motion tracker your changes are discarded.
To change the initial position of something after applying tracking you should Reset, make changes, and then Apply again.
Disable the Motion Tracker when your changes and its analysis are done (or turn off its preview). I do not recommend removing this filter when you are done loading keyframes because if you need to make an adjustment, this filter must still be available to list it in the dialog and get its tracking data.
More New Features!:
Added new time filters: Speed: Forward Only and Speed: Forward & Reverse. These are usually friendlier to use than Time Remap. The forward only version does not usually require converting the clip first unlike Time Remap and Speed: Forward & Reverse.
Added saving and loading filter sets. A filter set is a collection of filters. The copy and paste buttons in the Filters panel open new Copy Filters and Paste Filters dialogs. When copying filters, you can optionally give it a name, in which case it will be saved to use not only in the current project but also all projects and sessions. Giving it a name still also puts it on the system clipboard. When pasting filters, you can choose to paste from the clipboard or a saved filter set. A few examples are included: Obscure With Blur, Obscure With Mosaic, Text Simple with Gradient Back.
Added an Add To Timeline button to many things in the Open Other menu/dialog. That usually saves a couple of steps.
Added a visual rectangle control to the Mask: Simple Shape filter.
Holding Shift while dragging a point in the Corner Pin filter moves all corners together.
Added faster and better quality YADIF deinterlacer plus addition of BWDIF deinterlacer.
Added 10-bit export presets under the "ten_bit" category.
Added support for Intel ("qsv") AV1 and VP9 hardware encoders on Windows including 10-bit for AV1.
Fixes and General Improvements:

Fixed image padding not transparent during a transition.
Added low disk space warnings to the Properties > Convert and Reverse actions.
Fixed loading projects made with version before 19.06 using comma for decimal symbol.
Fixed Shotcut's sound on Windows not following the output device when it changes.
Many other smaller things not mentioned here - see Git history.
Drawbacks and Limitations:
Settings > Theme is gone due to a bug or limitation in Qt 6 Quick Controls. The Shotcut dark or light theme now strictly follows the system settings. On Linux, that is hit-or-miss depending on the desktop environment and its version (and, sadly, not the AppImage). For many people this will not make a difference. For many others, it might make you want to switch your system to dark mode. I do not expect this situation to change in the near future (2023). Yeah, I am not real happy about it either, but it is what it is - which means all comments, forum posts, and bug reports about this will be ignored, hidden, or closed.
Settings > Player > External Monitor with a system monitor (not Blackmagic peripheral) is no longer available.
Export progress no longer shows on the Windows taskbar icon.
The minimum version for Windows is now Windows 10. Older systems can continue to use version 22.12.
The minimum version of our non-Flatpak Linux binaries is now based on Ubuntu 20.04 LTS, which uses glibc 2.31. This is due to modern C++ requirements in dependencies, and bundling libstdc++ can break non-bundled system components. Previously, it was based on Ubuntu 18.04 LTS, whose support period ends in April, 2023. Older systems can continue to use version 22.12, or maybe the Flatpak will work.

New in Shotcut 23.03.03 Alpha (Mar 6, 2023)

ALPHA:
Alpha here means that it is not feature complete, but there are many exciting changes that we want people to try out and provide feedback. If it eats your homework, do not complain. It is just for toying around and testing. There will be a beta version around the end of March or early April to add or complete more features. The final release is planned for the end of April.

Motion Tracker Filter:
This is currenty just a toy filter with plans to apply the analysis results to other filters in the beta. For now, you can choose a region to track with a visual rectangle control and see that it is working. You can preview the tracking and run analysis to improve playback/export performance. When released, this filter will not do any rendering itself outside of the preview. It is intended to cooperate with many other filters. It is included in the alpha to test out the new build components and offer a sneak peak of this new feature.
Fixes and General Improvements:
Less audio crackling when audio source is not 48000 Hz sample rate.

New in Shotcut 22.09.23 (Sep 27, 2022)

Added limited support for reading WebP Animation.
Show audio-clips without album art as a checkboard for transparent instead of white.
Added the GPS Graphic video filter (see its presets).
Added the gopro2gpx utility to let you export a GPX file from a GoPro video using Properties > menu > Export GPX. This saves the .gpx in the same folder as the video file with the same name but different exension.
Added Fisheye video filter (see its presets).
Deprecate and hide the Lens Correction video filter since it is low quality (no interpolation) and now there is Fisheye.
Added snapping to the playhead to Keyframes.
Added Help > Actions and Shortcuts:
Provides a unified action search and shortcut editor.
Replaces the old Keyboard Shortcuts... item in the Help menu and takes its keyboard shortcut ?.
/ is also a default shortcut, and either shortcut can be changed.
Searches both action name and shortcut.
Press Return/Enter within search to move focus to the list of actions.
Press Return/Enter on a selected action to trigger it and close the dialog.
Shift, Ctrl, or Alt + Return/Enter on a selected action to trigger it and NOT close the dialog.
Double-click an action to trigger it but NOT close the dialog.
The dialog is not modal so you can leave it open and to the side while working.
Press Esc when the dialog has focus to close it.
Press F2 when an action is selected to edit its first shortcut.
Single-click a selected shortcut to enter edit mouse using the mouse. This means you typically need two single clicks: one to select, the second to enter into edit mode.
You can Tab out of edit mode to navigate focus to the apply button and press Space to trigger the apply. It is intentional that you cannot assign Tab as a keyboard shortcut to an action.
There are some keyboard buttons such as J/K/L that are reserved and cannot be used in a shortcut. You will see an error message when you try to apply it.
You can define up to 2 shortcuts per action! You may want to leave the default as well as add your preferred shortcut.
A big portion of the UI had to be rewritten to support this. As a result:
All panel (hamburger) menus are consistently on the left/first.
Panel-specific Options sub-menus were moved to Settings main menu.
The keyboard shortcut to switch the player between Source and Project is now P.
Various hidden or under-exposed actions now have a menu item somewhere including a new Player main menu.
Many translations will be lost.
The default shortcuts to change the current track now require Ctrl+Alt in addition to cursor up and down.
Improved support for custom video transitions:
There is a folder now in the App Data Directory named transitions where you can store these.
All files in the transitions folder are listed in transition Properties, the Mask: From File video filter, and the Slideshow Generator dialog.
Added a favorite button in transition Properties and Mask: From File that copies your chosen custom file to the transitions folder.
Added a quick preview to transition properties.
Added the ability to drag-scroll/pan using the middle mouse button (press mouse wheel) to Timeline, Keyframes, and the player when zoomed in.
Improved the Filters picker:
Added translatable keywords to facilitate search. For example, "transform" includes Size, Position & Rotate.
Added the English filter name in an untranslatable manner to the keywords so people using a translation can more more easily find things based on proliferic English advice.
Added support for a small animated icon.
Added the alpha Operation, Reverse, and Invert parameters to the Mask: Draw video filter.
Added Settings > Reset... to reset all settings including hidden ones.
Fixed Move Track Up or Move Track Down breaks the order of blending/compositing.
Fixed opening files with a % in their path or name.
Fixed sometimes a date does not appear in Playlist.
Fixed Old Film: Scratches video filter not working (broke in version 22.04).
Fixed Stabilize video filter uses invalid analysis data after pasted.
Fixed File > Open MLT XML as Clip... changes the current Video Mode.
Fixed audio artifacts introduced after splitting a clip that has been converted or reversed using the better/large/DNxHR option.
Fixed Text: Rich filter's toolbar may not reflect the current text color.
Upgraded FFmpeg to v5.1.0
Upgraded dav1d AV1 decoder v1.0
Upgraded AOM AV1 encoder to v3.4.0
Upgraded libvpx VP8/9 encoder to v1.12.0

Replaces the old Keyboard Shortcuts... item in the Help menu and takes its keyboard shortcut ?.
Searches both action name and shortcut.
Press Enter within search to move focus to the list of actions.
Press Return/Enter on a selected action to trigger it and close the dialog.
Shift, Ctrl, or Alt + Return/Enter on a selected action to trigger it and NOT close the dialog.
Double-click an action to trigger it but NOT close the dialog.
The dialog is modal so you can leave it open and to the side while working.
Press Esc when the dialog has focus to close it.
Press F2 when an action is selected to edit its first shortcut.
You can Tab out of edit mode to navigate focus to the apply button and press Space to trigger the apply. It is intentional that you cannot assign Tab as a keyboard shortcut to an action.
There are some keyboard buttons such as J/K/L that are reserved and cannot be used in a shortcut. You will see an error message when you try to apply it.
You can define up to 2 shortcuts per action! You may want to leave the default as well as add your preferred shortcut.
A big portion of the UI had to be rewritten to support this. As a result:
All panel (hamburger) menus are consistently on the left/first.
Panel-specific Options sub-menus were moved to Settings main menu.
The keyboard shortcut to switch the player between Source and Project is now P.
Various hidden or under-exposed actions now have a menu item somewhere including a new Player main menu.
Many translations will be lost.
Improved support for custom video transitions:
There is a folder now in the App Data Directory named transitions where you can store these.
All files in the transitions folder are listed in transition Properties, the Mask: From File video filter, and the Slideshow Generator dialog.
Added a favorite button in transition Properties and Mask: From File that copies your chosen custom file to the transitions folder.
Added a quick preview to transition properties.
Added the ability to drag-scroll/pan using the middle mouse button (press mouse wheel) to Timeline, Keyframes, and the player when zoomed in.
Improved the Filters picker:
Added translatable keywords to facilitate search. For example, "transform" includes Size, Position & Rotate.
Added the English filter name in an untranslatable manner to the keywords so people using a translation can more more easily find things based on proliferic English advice.
Added support for a small animated icon. (This is a work-in-progress; only a handful so far, more but not all to be included in the release.)
Added the alpha Operation, Reverse, and Invert parameters to the Mask: Draw video filter.
Added Settings > Reset... to reset all settings including hidden ones.
Upgraded FFmpeg to v5.1.0
Upgraded AOM AV1 encoder to v3.4.0
Upgraded libvpx VP8/9 encoder to v1.12.0
Upgraded VMAF to v2.3.1
