One take. Thirty seconds. Native 4K.
Seedance 2.5 is ByteDance's next video generation model: a single 30-second pass with scene changes, tempo shifts, and synchronized sound — no stitching, no post. Atlas Cloud is preparing day-0 API access. Get in line before it goes public.
The Headline Feature
Today's video models top out at a few seconds per pass, and longer stories are stitched together in post. Seedance 2.5 generates the full 30-second arc in one native pass — camera moves, scene changes, and tempo shifts included.
The opening shot sets scene, light, and mood from your prompt and references.
The model transitions locations mid-take while characters and grade stay locked.
Pacing accelerates or breathes — motion and score shift together, in sync.
The take resolves as one continuous shot. No seams to hide, nothing to stitch.
What's New in 2.5
Every headline capability announced for Seedance 2.5, in one place.
Mix up to 50 images, clips, and audio tracks in a single request — lock characters, products, locations, and style across the whole take. Seedance 2.0 accepts 12.
Draft at 720p, iterate at 1080p, master at native 4K — and keep that fidelity across the full 30-second take, no upscaler required.
Audio is co-generated with the visuals, not layered on after. Dialogue lands on lips, foley lands on frames, the score follows the cut.
Change one element of an existing clip — a product, a costume, the weather — while motion, camera, and lighting stay untouched. No full re-render.
Titles, captions, and signage render cleanly across languages — built for localized cuts and global campaigns.
Optimized spatial-temporal attention holds character appearance, lighting, and motion style across the full duration of the take.
