Shotcut 25.07.26

What's new in this version:

- Added a Whisper.cpp (GGML) model downloader to the Speech to Text dialog
- A model is no longer included in the download and installation reducing their sizes
- Improved the System theme to follow the operating system palette on Windows (darker and more contrast), and improved its appearance on macOS dark mode
- Added Settings > Theme > System Fusion that combines the operating system palette with the monochrome, symbolic icons of the Fusion themes.Added an Outline video filter that uses the input alpha channel--useful with rich text or assets with a transparent background.
- This means that, like Drop Shadow, it will not work as expected when used after a text filter on a video or image clip. Rather, you must use a text clip (transparent color generator with text filter) on an upper track.

Other New Features:
- Added the ability to drag the waveform peak line to adjust audio gain
- Added Settings > Timeline > Adjust Clip Gain/Volume to turn off the above

Added rolling an edit/trim to Timeline:
- Hold Ctrl (command on macOS) while trimming to simultaneously trim the neighbor clip
- Added a Soft Focus filter set
- Added Audio/Video duration to the Slideshow Generator dialog, defaults to 4 hours
- This facilitates using Slideshow Generator to make transitions between everything when including both video and images. (It still respects the source duration and in & out points; duration here is a maximum.)

Surround Sound Mixing Improvements:
- Added fader and surround balance to the Balance audio filter if channels > 2
- Added support for 4 channels in the Copy Channel audio filter

Added Channels toggle buttons to many audio filters:
- Band Pass
- Compressor
- Delay
- Downmix
- Equalizer: 3-Band
- Equalizer: 15-Band
- Equalizer: Parametric
- Expander
- Gain/Volume
- High Pass
- Low Pass
- Limiter
- Mute
- Noise Gate
- Notch

For example, now you can:
- Copy stereo music to the rear channels and use the fader in the Balance filter to reduce its volume,
- Downmix spoken word into the center channel and apply a Band Pass filter to it, and
- Route music or sound effects to the low-frequency channels and apply a Low Pass filter to it

Other Improvements:
- Changed the default Export > Audio > Rate control to Average Bitrate for AAC, Opus, and MP3
- Added the ability to add/use multiple Mask: Apply filters
- Added support for Scrub While Dragging to trimming on the timeline
- Added hold Shift to ripple-trim when Ripple is turned off
- Added French (Canadian) and Lithuanian translations

Fixed:
- Fixed Mask: Apply with multiple Mask: Simple Shape (broke in v25.05)
- Fixed exporting projects containing only Generator clips on Windows (broke in v25.05)
- Fixed converting 10-bit full to limited range (broke in v25.01)
- Fixed dropdown menus using Settings > Theme > System on Windows
- Fixed Balance and Pan audio muted channels if audio channels > 2
- Fixed Export > Use hardware encoder fails with H.264 on macOS 15
- Fixed Properties > Convert or Reverse for iPhone 16 Pro videos with Ambisonic audio
- Fixed a single frame fade out filter would either mute or make black
- Fixed repairing a project (e.g. broken file links) with proxy turned on
- Fixed doing Freeze Frame on the first frame of a clip
