Shotcut 24.06.26

What's new in this version:

New Stuff:
- Added SVT-AV1 encoder (faster non-hardware AV1 encoder)
- Added support for AVIF (AV1) images
- Added a Drop Shadow video filter that uses the input alpha channel. (This means that it will not work as expected when used after a text filter on a video clip; rather, you must use a text clip on an upper track.)
- Added a Vibrance video filter. This is similar to Saturation, but Vibrance is sensitive to the current saturation instead of adjusting all values equally as in saturation. This is especially helpful to prevent affecting skin tones
- Added the Mid-Side Matrix audio filter for processing these kinds of microphones into proper stereo sound
- Added Keyframes > Scrub While Dragging
- Added Playlist > menu > Columns
- Added support for DJI LRF (MP4) files as a proxy

Fixes and Changes:
- Improved handling for some variable frame rate videos. Now, Properties tries to show the file's target frame rate and extends the variable detection logic to include strange average frame rate values (what previous versions showed in Properties)
- Changed Playlist Tiles view mode to show Date instead of In/Start
- Fixed using graphics (text, image, etc.) on upper video track with GPU Effects
- Fixed an off-by-one frame bug in the duration for Glaxnimate animations
- Fixed Undo does not work for time filters
- Fixed spamming (Undo) History when using the timeline fade controls
- Fixed preview color with GPU Effecs is inaccurate
- Fixed Timeline > Select None does not clear the Filters panel or VUI
- Fixed single click does not reset a multi-selection
- Fixed Export > Codec > Quality hint not updated after changing Rate control
- Fixed Properties > Proxy > Make does not regenerate if already exists
- Fixed changing Properties (except Speed) affects clips on other tracks with Ripple All Tracks turned on
- Fixed drag from Source and drop to Source changes Playlist
- Fixed Automatically Add Tracks changes the current video track, which can cause unexpected behavior with Properties > Speed change, for example
- Fixed files generated automatically in the project folder (.stab, .rawr, etc.) are incorrectly generated in the app data's autosave folder in the app session immediately after Shotcut recovers an auto-saved project
- Fixed changing Properties can delete a timeline clip
- Fixed selected filter changes unexpectedly by changing tabs or clicking filter categories
- Fixed Properties > Audio > Track > All
- Fixed the project folder when running an autosave-recovered session
- Fixed Settings > Timeline > Auto Add Tracks creates too many tracks when drop multiple clips to Timeline
- Fixed new Settings > Time Format not used in several places
- Fixed View > Application Log > Previous not working after the first time
- Fixed Properties > menu > View Bitrate hiding the first second
- Upgraded Qt to version 6.7 on macOS, Windows, and Flatpak
- Upgraded dav1d to version 1.4.2
- Upgraded FFmpeg to version 7.0
- Upgraded OpenCV to version 4.9.0
- Upgraded VMAF to version 3.0.0
