Where this family fits.
Preparing a bounded Seedance 2.5 shot brief
Checking 4–30s, 480p / 720p and adaptive / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 / 21:9 before you run
Pacing a Seedance 2.5 shot anywhere between 4 and 30 seconds
Deciding per request whether Seedance 2.5 renders audio
Carrying up to 30 reference images into a single Seedance 2.5 shot
What not to assume.
Every request has to fit the Seedance 2.5 envelope of 4–30s and 480p / 720p; values outside it are refused before rendering.
Audio is chosen per request on Seedance 2.5, and the choice cannot be changed once the job starts.
Motion can drift in identity, geometry, small text, logos and continuity, so Seedance 2.5 output still needs review before publishing.
A Seedance 2.5 request is asynchronous: a pending job is not a finished clip.
What the Seedance 2.5 envelope allows
Seedance 2.5 currently lists 4–30s durations, 480p / 720p output and adaptive / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 / 21:9 aspect ratios. Length is a free range from 4 to 30 seconds, so pacing is set by the request rather than by the model.
Choosing the workflow
Seedance 2.5 starts from a prompt alone or from a reference image, so the first decision is which of the two carries the framing. Up to 30 reference frames are accepted per request, so more than one source frame can carry the look. Audio is a per-request switch, so the same brief can be run silent or scored.
How a request runs
Vizify inspects the selected policy before it sends the request, so a value outside the published envelope is refused rather than quietly adjusted. Video generation is asynchronous: a pending job is not a completed artifact, and the returned clip still needs a review pass for identity, geometry, small text and continuity before it is published.
