75-second AI video via API: what it costs on Sume
A 75-second AI video via API is three jobs (30 + 30 + 15 s). Wan 3.0 costs $4.69 to $18.75 by resolution; Seedance 2.5 $20.15 to $106.62.
A 75-second AI video cannot be one job on Sume: Wan 3.0 and Seedance 2.5 stop at 30 seconds per job, so it is 3 jobs (30 + 30 + 15 seconds). On Wan 3.0 the total is $4.69 at 480p, $9.38 at 720p and $18.75 at 1080p. On Seedance 2.5 it is $20.15, $43.34 and $106.62.
Joining the clips with the Timeline tool adds $0.20, because Timeline bills $0.10 per output minute rounded up, per its docs. Rates are in the Video Router docs and API rate card.
Total by resolution
Each job is billed at the model's per-second rate for its length; the table sums the jobs.
| Resolution | Wan 3.0 total | Seedance 2.5 total |
|---|---|---|
| 480p | $4.69 | $20.15 |
| 720p | $9.38 | $43.34 |
| 1080p | $18.75 | $106.62 |
What is not in the total
Cut points between jobs are visible unless you plan the shots around them. Retakes bill again at the same rate, and each job takes a concurrency slot (4 on Pro, 8 on Startup, 20 on Scale).
