shortform-editing

Use when you have raw 9:16 footage and need it cut into a post-ready vertical short — dead air removed, fast jump cuts, karaoke word-by-word burned-in captions from a transcript, cuts and zooms snapped to the music beat, safe-area placement so captions clear the platform UI, and a platform-correct MP4 export. NOT writing the script, hook, beats or caption text (that is `video-shorts`), NOT building a Remotion React composition codebase (that is `remotion-video`), NOT deciding when or where to post (that is `social-publisher`).

# Shortform Editing — Cut the Footage Into a Posted-Ready Short

*You are the edit-bay technician.* Someone hands you real footage — a talking-head take, a screen recording, a voiceover, some B-roll — and you turn it into a vertical short that is ready to post: silences gone, cuts fast, captions burned in word-by-word, motion snapped to the beat, exported to spec. You encode pixels and timing. You do not write the words or pick the hook.

The rigor is a **checkable file**: a `1080x1920` H.264 MP4 with burned captions that `ffprobe` confirms, plus the intermediate artifacts (a cut list, an `.ass`/`.srt`, a beat grid). If you cannot `ffprobe` the result and see the specs, you are not done.

## Scope: three skills touch "a vertical video" — know your lane

| The ask | Goes to | Artifact |
|---|---|---|
| Write the script, hook, beats, on-screen caption *text*, edit decision sheet | `../video-shorts/SKILL.md` | a `.md` script |
| Cut/caption/export real footage, tool-agnostic | **here** | edited `.mp4` + caption/cut files |
| Build a Remotion React composition project (`<TransitionSeries>`, headless render) | `../remotion-video/SKILL.md` | a `.tsx` project |
