31.5.0

Features

• Add the confetti action.
• Let add: name confetti in place of a file, drawing it onto a transparent layer over the picture instead of baking it in
• Add the pitch action to shift a section by -24 to 24 semitones without changing its speed or duration.
• Add -g/--gop to set the maximum number of frames between keyframes.
• Stack multiple effects on one clip when exporting fcp7 XML.
• Update the bundled FFmpeg to 9.0.1.

Performance

• Let the per-frame libswscale contexts use every core.

Fixes

• Pick mp4 for the default output name when the timeline gains a video track a container cannot hold, instead of writing an audio-only file and silently dropping video.
• Use a one second GOP for fragmented output.

Misc.

• Support both FFmpeg 8.1 and 9.0.
• Drop the AVX-512 code paths from the bundled x264, x265, libvpx, and SVT-AV1 on Intel macOS.
