What it does
Left half is the input, right half is what the command produced. Every before/after demo, with the exact command under each one → — all of it generated from synthetic footage by python3 demos/build.py, so you can rebuild every frame of it yourself.
Get started
npx ffmpeg-skill contract --json
# or: python3 scripts/_contract.py --json
npx ffmpeg-skill contract --json --static
