Minimal:
Add b-roll from my clips over the parts where I talk about something you can show.
Standard:
Add b-roll to my UGC hook and demo video from the clips I uploaded. Look for these shots. Selfie hook take. Screen recording or over-the-shoulder demo. The result. Product in hand. Pacing: hook 3s, demo 15-25s, result 5s, CTA 3s. Put each clip on the words it shows and keep my audio running underneath.

Add b-roll to my UGC hook and demo video from the clips I uploaded. Look for these shots. Selfie hook take. Screen recording or over-the-shoulder demo. The result. Product in hand. Pacing: hook 3s, demo 15-25s, result 5s, CTA 3s. Put each clip on the words it shows and keep my audio running underneath. Keep captions on during b-roll. Avoid these. Too polished. Demo with no visible result. A hook that fits any product. Don't use any clip twice. When you're done, list which clip went where with timestamps.
Why these settings
- The shot list is the one from our UGC hook and demo video page. Asking for shots by what's in them is faster than digging up file names.
- "Keep my audio running" stops it from cutting your voice along with the picture.
- The pacing line (hook 3s, demo 15-25s, result 5s, CTA 3s) sets how long b-roll stays before it cuts back.
- A list of placements with timestamps makes the result quick to check.
Fixes
- B-roll stays too long. "Come back to my face after 3 seconds of b-roll."
- Wrong shot. "At 0:22 use the close-up of my hands instead."
- Cuts away mid-word. "Only cut to b-roll at the end of a word."
FAQ
Does it use stock footage? No. It only uses the clips you upload. We don't generate footage.
Do I need every shot before I start? No. Run it with what you have. Then film the rest of the shot list (selfie hook take, screen recording or over-the-shoulder demo, the result, product in hand), upload it to the same project, and run the prompt again.
