i made a 90-sec Hollywood-style motorcycle chase short, completely 100% AI-generated.
Two riders, five pursuers, one packed highway. No crew, no stunts, just
Seedance 2.5 and a very detailed prompt "bible" to keep 5 bikes chasing in
the right direction.
The hardest part wasn't the visuals, it was physics. Seedance 2.5 kept putting the chasers IN FRONT of the getaway bike instead of behind it. Then i had to engineer a whole camera system + spatial rules to fix it. Then redesigned the ending after gunfire got flagged by moderation.
