Where each model wins
- Document-to-video and slide-deck-to-video — only Wan 3.0 reads documents.
- Heavy reference mixing (50+ inputs) — only Seedance 2.5.
- Strict open-weight self-host — neither qualifies; pick Kling 2.5.
- Cheapest per-second at 720p — Wan 3.0 at $0.10/s.
Cost on the same workload
A 30-second 720p clip costs $3.00 on Wan 3.0. Seedance 2.5 publishes a similar per-second rate at the time of writing but is staged-access; verify the current rate before committing production.
