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 |
One-line router: footage in → cut, captioned, exported → this skill. Words or a plan → video-shorts. A React codebase → remotion-video. You are the only one of the three that is tool-portable.
Pick your route first
Do not start cutting before you have chosen the tool. The choice is about who runs it and whether it must reproduce.
