Fix one bad shot in a 3-minute AI video for $2.18
A 12-shot, 3-minute AI video costs $22.86 to build. Re-rendering one 15-second shot and re-composing costs $2.18 on Sume.
Keep shots as separate jobs
If a 3-minute video is built from 12 separate 15-second Wan 3.0 jobs, one bad shot is one re-run. A single 3-minute generation would restart everything.
| Action | Basis | Cost |
|---|---|---|
| Build: 12 shots | 12 jobs at $1.88 | $22.56 |
| Build: compose 3 min | Timeline, 3 output minutes | $0.30 |
| Fix: re-run shot 7 | One 15 s Wan 3.0 job | $1.88 |
| Fix: re-compose | Timeline, 3 output minutes | $0.30 |
| Fix total | $2.18 |
Plan before paying
Timeline has a /plan step that is not billed, so check slot timings before the paid compose. Store each shot's job result so replacing one is a swap of one URL.
