Why Seedance 2.5
30-second clips in a single pass
ByteDance shows a full 30-second generation with no stitching or seams — well beyond what earlier Seedance versions produced in one shot. Longer narrative beats without chaining clips together.
Up to 50 reference inputs at once
Feed Seedance 2.5 as many as 50 references simultaneously — images, audio, style references, even 3D white models — and the model honors all of them to steer style, motion, and composition.
Localized, region-level editing
Change one region of a clip without regenerating the whole video. ByteDance highlights flexible localized editing, so a single tweak no longer costs you a full re-render.
3D blockout (白模) input
Pre-stage camera and composition with 3D white-model input, giving directors tighter control over framing and motion before the final frame is rendered.
~20% better prompt adherence
ByteDance reports roughly 20% improved prompt accuracy over the prior generation — the model follows instructions more precisely, so you reach a usable take in fewer attempts.

How to use Seedance 2.5
1
Start with Seedance 2.0 on Sunra today
Open Sunra Video and select Seedance 2.0 — the current production Seedance model, included in every Sunra subscription. This is the fastest way to make Seedance video while 2.5 rolls out.
2
Describe your clip or upload references
Type a prompt with the motion, mood, and subject you want, or upload a still for image-to-video. Seedance 2.5's headline upgrade is up to 50 reference inputs — when it lands on Sunra, the same prompt workflow carries over.
3
Generate, review, iterate
Most Seedance 2.0 clips come back in under 60 seconds, so you can run several variations quickly. Chain clips in Sunra Flow for longer sequences today; Seedance 2.5's single-pass 30-second output will shorten that workflow once available.
