Minimal:

Full:

Look for these shots. Screen recording of the task. Face recording, synced. The result.
Pacing: 3-5 seconds per step, zoom on each click.
Put each clip on the words it shows and keep my audio running underneath.
Keep captions on during b-roll.
Avoid these. Face too big or too small. Screen unreadable. Narration behind the click.
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 app walkthrough 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 (3-5 seconds per step, zoom on each click) 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 (screen recording of the task, face recording, synced, the result), upload it to the same project, and run the prompt again.
