Video Transformation

ffmpeg-based video operations: editorial cuts, transcoding, scaling, muxing, and derivative exports. Outputs land in the workspace root .mediaskills/generated/ unless you pass --output. Override base path with $MEDIASKILLS_DATA_DIR.

When to use

• This skill — trim, concat, transcode, scale, proxy, frame/audio extraction, GIF, replace audio, and similar ffmpeg transformations.
• inspect — read metadata first (duration, codecs) before choosing trim boundaries or transcode settings.
• timecode — frame-accurate timecode math when working in HH:MM:SS:FF or HH:MM:SS;FF instead of seconds.
• audio — normalize or process audio before replace_audio.py.
• subtitles — mux soft subtitles without burning; use this skill when the container needs re-wrapping.
