Capabilities

What Seedance 2.5 can do

Cinematic prompt following

Write prompts with subject, action, camera movement, lighting, pacing, and composition in one brief of up to 5,000 characters.

Reference-driven generation

Add reference images and up to three reference video clips to keep characters, products, and camera moves consistent across the shot.

Up to 30 seconds per clip

Pick any length from 1 to 30 seconds — enough for full ad spots, product stories, and complete scenes in one generation.

Start with camera language

Seedance 2.5 prompts are easier to judge when the camera move is explicit: dolly in, tracking shot, handheld, orbit, or locked-off frame.

Separate subject and motion

Describe what the subject is, then describe what changes. This keeps Seedance 2.5 image-to-video tests from drifting too far.

Add negative constraints

Mention what should not happen: no logo changes, no extra people, no warped hands, no text overlays, or no sudden cuts.
