Why these settings

The track direction comes from our cinematic b-roll video page.
With no speech to duck under, the track sets the pace, so the prompt ties the cuts to the beat.
Naming a file you uploaded stops it from picking from the library.
"No sound effects" keeps it from adding extras you didn't ask for.

Fixes

Cuts land off the beat. "Move every cut onto the nearest beat."
Wrong mood. "Something slower, around 80 BPM, piano, no drums."
Track starts mid-phrase. "Start the track from its beginning and trim the end."

FAQ

What music fits a cinematic b-roll video? Ambient, cinematic, or a slow track. Describe the mood in the prompt or upload the exact track.
