Edit video and audio with local FFmpeg: cut, join, reframe, speed, captions, overlays, silence removal, sync, loudness, HDR to SDR, platform exports and checks. Use whenever the user mentions a video or audio file (mp4, mov, wav, m4a), footage, captions, a reel or short, YouTube/TikTok delivery, LUFS or ffmpeg, even without saying "edit". Needs FFmpeg 6.1+ and Python 3.10+; stdlib only, no cloud.

# ffmpeg-skill

## Quick start

Run `python3 <skill-dir>/scripts/<name>.py`; the table below routes requests, `--help` lists every flag.
MCP `tools/list` shows the core 12; the other 30 of the 42 tools stay callable by name.

Shared flags (the rest, codec defaults and `--hw`: `references/flags.md`):
`--dry-run` (plan, write nothing), `--json` (output, probe, commands), `--json-brief` (status + `summary`),
`--overwrite` (step 7), `--timeout SECONDS` (default 1800, `0` = none; `kind: timeout`).

Writing tools run nothing under `--dry-run`; the measuring tools (`probe`, `check`, `sync`, `multicam`,
`scenes`, `cropdetect`, `report`, `silence`, `loudness`, `stabilize`, `overlay`) may still run
ffmpeg/ffprobe without writing artifacts; `verify` ignores the flag. Per tool: `contract --json` `dry_run`.
