Why these settings

  • The shot list is the one from our testimonial 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 (calm, 8-12 seconds per point) 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 (interview framing, slightly off-axis, b-roll of them using the product, their workspace, the product screen), upload it to the same project, and run the prompt again.
