Vyra describes every scene when you upload, so you can ask for a shot by what's in it. You don't need file names.

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.
