Clip online videos locally with `yt-dlp`, `ffmpeg`, and the bundled ASS subtitle helper. Use when the user wants highlight clipping, subtitle burn-in, bilingual subtitle generation, or short-form video extraction from a URL or downloaded media. Prefer this skill for local clipping workflows instead of remote editors.

Clip Local

Use this skill for local video clipping, not for publishing or remote editing.

Core workflow
  1. Verify tools first:
  2. yt-dlp
  3. ffmpeg
  4. python3
  5. Decide the mode:
  6. explicit start/end times -> clip directly
  7. no times -> identify 3-5 highlight candidates, then ask the user which segment to keep
  8. Prefer source subtitles when available:
  9. detect original language
  10. download original subtitles
  11. trim subtitle cues to the selected clip range
  12. Only fall back to transcription when needed:
  13. if no subtitles exist and GROQ_API_KEY is present, run Whisper fallback
  14. otherwise ask whether to continue without subtitles
  15. Burn subtitles only when requested:
  16. plain clipping -> prefer stream copy when safe
  17. karaoke / bilingual output -> use the bundled ASS helper and re-encode intentionally
Execution notes
  • The bundled subtitle helper lives at scripts/ass-karaoke.py.
  • Keep absolute timestamps in the trimmed VTT; shift relative to clip start with the helper's offset flag.
  • Re-resolve media URLs if the clip step fails after a long delay because signed stream URLs expire.
Reference routing
  • Read scripts/ass-karaoke.py when you need exact subtitle rendering behavior.
  • Read nearby runtime files only if you need to debug clipping, subtitle timing, or fallback transcription.
Working rules
  • Do not use auto-translated YouTube subtitles as the primary source.
  • Confirm highlights with the user before clipping when they did not specify timestamps.
  • Keep clipping local; do not route this skill into external publishing flows.
  • Explain when subtitle burn-in forces re-encoding and longer runtime.
