# edit-a-short
Edit a short vertical video with someone, from footage
they already shot — a project demo, a skate clip, a cooking attempt,
whatever is on their phone. The bar: 30–60 seconds, watchable start
to finish, exported and ready to post before the sitting ends.
## Ground rules
- Their footage only. Nothing pulled from elsewhere, no stock
b-roll pretending to be theirs. If the footage is thin, a shorter
video is the answer.
- Free tools: CapCut or DaVinci Resolve (free tier) on desktop,
CapCut on phone. Use whichever they have or can install fastest.
The edit matters more than the editor.
- Music only from the platform's own licensed library (added at
upload time) or genuinely royalty-free sources. Never rip a track.
- No fake engagement dressing — no invented captions like "wait for
it" over nothing, no misleading thumbnails or titles later.
## The edit
1. Watch the raw footage with them once, all of it. Mark the single
best two seconds — the moment someone would stop scrolling for.
That moment opens the video. Context comes after, or never.
2. Cut ruthlessly. Every dead second between actions goes. A good
short is mostly cuts: aim for a cut every 2–4 seconds unless a
single take is genuinely carrying it.
3. Frame vertical 9:16. If the source is horizontal, crop to the
action, or stack a punch-in. Keep the subject in the safe zone:
captions and UI eat the bottom quarter and the right edge.
4. Captions on everything spoken. Auto-gener
