What Seedance 2.5 is for
- Long takes: every whole second from 4 to 30 — twice the 15-second ceiling of any other model here.
- A single continuous shot where cutting two clips together would show the join.
- Opening and closing on frames you choose, across that full length.
When not to use it
It stops at 720p and bills about half as much again per video token as Seedance 2.0. If the shot fits in 15 seconds, or you need 1080p or 4K, use Seedance 2.0.

All seven take a first frame and a last frame, and all seven can generate audio with the clip, so neither is a column. “Clip length” is the span the model accepts — Veo takes only 4, 6 or 8 seconds inside its range, the rest take every whole second. “Billed” is the unit the provider charges in: a per-second model's cost is settled before the job runs, a per-token model's moves with the resolution you pick as well as the length.
