10-minute video compose: Timeline costs $1.00, plan first
Timeline bills $0.10 per output minute, so a 10-minute video is $1.00 and a 30-minute one is $3.00. Limits: 1,800 seconds and 200 slots.

The long-video line item
For long videos the generation cost is shots, but the compose cost is Timeline: $0.10 per output minute rounded up.

| 5 min | $0.50 |
| 10 min | $1.00 |
| 30 min (limit 1,800 s) | $3.00 |
Preflight
Call /plan first. It is not billed and shows if slots overlap. Up to 200 slots per Timeline.
