What is Seedance 2.5?
Seedance 2.5 is the long-form tier: it animates a single still into one continuous clip of up to 30 seconds at 720p. Because the whole thing is generated as one piece, the motion does not drift or jump the way stitched short clips do.
How the people who built the model describe it:
“Seedance 2.5 can generate high-quality, 30-second audio-video clips in a single pass and supports multiple rounds of extension.”

What you can make with the Seedance 2.5 tool
These are the jobs people actually bring to Seedance 2.5, and the settings each one needs.
02
Multi-reference scenes
Assign different references to character appearance, locations, choreography, camera motion, transitions, and sound so each source has a clear job.
03
Creator sequences
Create social stories, product narratives, explainers, and campaign films with stable characters, lighting, and scene logic across multiple shots.
Seedance 2.5
A workspace shaped for the model
Seedance 2.5 puts the handful of controls that change the result most in front of you, and keeps the rest out of the way.
Official model example · ByteDance Seed
01
Coherent stories up to 30 seconds
Generate a complete short scene in one pass, with enough time for an opening, action, reaction, and resolution while visual context carries from shot to shot.
Official model example · ByteDance Seed
02
Cinematic multi-shot continuity
Improved shot-to-shot logic keeps character appearance, scene lighting, and visual style more stable through camera changes and transitions.
Official model example · ByteDance Seed
03
References with explicit roles
Combine text with image, video, and audio references to direct identity, composition, motion, camera language, transition rhythm, and sound in the same brief.
Official model example · ByteDance Seed
04
Edit by the timestamp
ByteDance gives Seedance 2.5 timestamp-level control: direct what happens from 0–4s and 4–8s in the prompt, or reference an existing clip and change one character, action, or background while the rest stays continuous — including green-screen replacement.
Official model example · ByteDance Seed
05
Change the camera, keep the performance
Camera-perspective editing re-shoots a clip with new camera movement while the characters, actions, and visual style stay as they were, and output goes up to 1080P in landscape, portrait, square, or cinematic framing.
