Seedance
ByteDance's video model with native audio and long clips.
About
Seedance is ByteDance Seed's audio-video generation model family, turning text, images, video and audio references into clips of up to 30 seconds with synchronised sound. It is available to developers through BytePlus and Volcano Engine APIs on token-based billing, and to consumers through ByteDance's Dreamina app on subscription plans.
Key features
- Text-to-video and image-to-video generation with native audio
- Clips from 4 to 30 seconds with multi-round extension
- Up to dozens of image, video and audio references per generation
- Video editing modes for revising existing footage
- Draft mode for cheaper test renders on supported versions
- API access for building video features into apps
Pricing
Pricing is not listed here, because it could not be verified from an official source at the time of writing.
API pricing is token-based and varies with resolution, length and inputs, and consumer prices come from Dreamina rather than the API — this combined figure could not be verified against a single official page, so check the route you actually plan to use.
Best for
Creators and developers who want reference-driven clips with native audio and longer durations.
Limitations to know
AI-generated video can contain distorted motion, faces, hands and physics, so inspect every clip before publishing. The official API restricts real-human-face references, costs rise fast with resolution and length, and consumer and API pricing are entirely different systems.
What users like
- Smooth, cinematic motion with synchronised native audio
- Strong character and scene consistency from many references
- Longer clips up to 30 seconds with extension for stories and ads
What users complain about
- Token and credit pricing that is hard to predict across two separate routes
- Faces, hands and complex motion breaking down in some generations
- Official API restrictions on real-human-face references and regional availability
