Captions

Turns a verbatim transcript into clean, readable burned-in subtitles with strict line, timing and cleanup rules, ready for DaVinci Resolve import.

What it does

  • Strips stutters, filler sounds, cut-off words and self-corrections so captions show what was meant, correctly written.
  • Maps spoken short forms to proper written forms (Brazilian Portuguese examples included) while preserving idioms and swear words — fixing grammar, not voice.
  • Enforces measurable formatting: max 42 characters per line, new cue at pauses ≥0.6 s or after 3.2 s, minimum 0.9 s on screen, 0.25 s tail after the last word, no overlaps.
  • Starts the first cue at 00:00:00,000 so Resolve's import doesn't shift the whole track.
  • Verifies product and personal names on the web; keeps global replacement rules in config and per-video fixes in caption_fixes.json.
  • Requires a read-through pass over every cue, grepping for leftover short forms, double punctuation and lowercase after full stops.

Who it's for

  • Creators and editors cutting YouTube/Reels/Shorts in DaVinci Resolve
  • Anyone who needs high-quality burned-in captions for mute viewers
  • Teams repeatedly turning Whisper-style transcripts into subtitle files

Example uses

  1. "Make captions from this transcript" → a cleaned captions_v1.srt respecting the 42-character limit.
  2. "The product name is wrong in the captions" → the spelling is checked online, added to caption_fixes.json, and the file is regenerated.
  3. "Convert the spoken contractions to written form" → word map applied first, phrase fixes after, output saved as a new versioned file.

When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/appariciojunior/video-editor-skills.git && mkdir -p ~/.claude/skills && cp -r video-editor-skills/skills/captions ~/.claude/skills/
