Cinematic scenes, character animation, nature and product shots — generated from a prompt or a still frame, with native audio available in the same pass.
Capabilities
Describe a full scene in plain language and get a coherent cinematic shot — camera language, lighting, multi-shot storytelling and art direction included.
Drop in a photo, illustration or product shot and watch it move with physics-aware, style-faithful animation. Optional last frame pins the ending.
Joint audio-video generation in a single pass: dialogue, ambience and score with lip-sync. Toggle it off when you want a silent master.
On Seedance 2.5, generate complete narrative arcs — setup, development and resolution — in one continuous take.
Lock the opening look with a still, and optionally pin the ending composition for product and character work.
Dialogue, score and ambience land with the picture — toggle sound off when you want a silent master.
An optimized pipeline returns finished shots while the idea is still warm. Credits only charge when a render finishes.
The next generation
Seedance 2.5 is ByteDance’s next-generation AI video model, now available on SpectGen. Feed it a prompt or a still frame and it produces cinematic video with native sound — including lip-synced dialogue, background music and ambient effects.
Create videos from 1 to 30 seconds in a single pass on 2.5, at 480p or 720p, across seven aspect ratios. Need higher resolution? Switch to Seedance 2.0 for up to 4K at 15 seconds.
Start from a written prompt, or upload a first frame — and an optional last frame — to lock the composition the model has to honour.
Generate synchronized dialogue, music and ambient effects in the same pass as the picture, with lip-sync that follows the performance.
Name the move in the prompt — dolly, crane, tracking, multi-shot arcs — and steer lighting, lens and pacing without a timeline.
Model comparison
Both models share the same studio workflow. 2.5 is the default for longer takes with native audio; 2.0 is the pick when you need 1080p or 4K.

Advanced capabilities

Pin the opening with a first frame, and optionally a last frame, so image-to-video holds the composition you already approved.
Seedance 2.5 runs 1–30 seconds in one continuous pass. Seedance 2.0, Fast and Mini cap at 15 seconds.
2.5 for long takes with audio, 2.0 for up to 4K, Fast for quicker drafts, Mini for the lowest cost per second.
