Pick your agent. Every command is ready to paste.
npx skills add appariciojunior/video-editor-skills --skill brollThe open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.
01
Install it
Run the command above, or upload the folder in Claude.
02
Ask naturally
Describe the task. Your agent loads broll when the request matches its description.
03
Name it if needed
If it does not trigger, say “use the broll skill”. In Codex, type $broll.
B-roll
A transcript-only cut silently drops every clip without words. Don't.
Spot it
- A clip with 0 words is B-roll.
- A clip whose "words" are song lyrics or another language (radio, a café) is B-roll too: check what the transcript says before treating it as speech.
- All clips recorded in sequence → keep the recorded order; B-roll sits where it was shot.
Watch it (the step people skip)
Pulling 5 frames per clip led to bad cuts. Look at 2 frames per second (a contact sheet, 8 per row, small) for every B-roll clip, and read what the creator says right before and after it. Questions:
- What is the action? Where does it start and resolve?
- Is there a natural transition? Example from a real edit: the camera goes into a backpack (frames go black) in one clip, and the next clip starts black and comes out of the bag onto an airport table. Cutting black-to-black makes a free, perfect transition; cutting by fixed length destroyed it.
- Which part is steady and well framed? Which part is out of focus or the operator fumbling?
- Is it vertical (phone held upright)? It will crop to the middle in a horizontal/4:3 frame: flag it.
Cut it
- Segment by time:
{"clip": "…", "broll": true, "in": s, "out": s, "why": "…"}. - Length follows the action: a quick cutaway 2–4 s, a transition sequence 6–8 s, an outro over a drive 10–15 s. A soft-focus shot gets the shortest slot.
- 100% framing, colour the timeline pieces green so A/B roll read at a glance.
- Natural sound stays on the voice track, but: a B-roll clip that is silent gets normalized up by +30 dB (pure hiss) → set it back to 0 dB; a clip with a radio/music in it fights the music bed → lower it 8 dB or so.
- The music rises on B-roll (see
music-and-sound).
Report
Each B-roll: timeline time, what it shows, why that range, anything flagged (vertical, soft focus).

Questions about Broll
What does the Broll skill do?
How to find, watch and cut B-roll in a vlog - clips with no speech placed by time between talking clips, chosen by their action and story, not a fixed length. Use when footage mixes talking clips (A-roll) and silent clips, or when the creator says the B-roll pacing feels wrong.
