Seedance 2.5 API is a video generation API that transforms text prompts, images, video clips, and audio references into continuous, single-take videos up to 30 seconds long, currently available as a pre-release through Evolink.
What is Seedance 2.5 API?
Seedance 2.5 API is a video generation service that accepts multi-modal inputs – text descriptions, reference images, video clips, and audio – and outputs a single continuous video take. It runs on the Evolink platform and requires an EvoLink API key. The API is in pre-release with expected access; launch resolution tiers are 480p and 720p, with durations from 4 to 30 seconds.
Key Features
- Multi-modal input – Accepts text prompts, images, video clips, and audio references as input to guide video generation.
- Single continuous take – Produces one coherent video output rather than separate clips, with seamless transitions specified in the prompt.
- Configurable duration – Supports durations between 4 and 30 seconds, allowing short loops or longer scenes.
- Resolution options – Launch tiers offer 480p and 720p output; higher resolutions (4K) appear in example galleries but are not part of the API release.
- Async job support – Uses polling or callback_url for asynchronous video generation, suitable for server-side workflows.
- Configurable model parameter – The API endpoint allows switching models via a configurable parameter, enabling future upgrades without code changes.
Who is it for?
- Film and video creators – Filmmakers and editors who need rapid prototyping of complex scenes with controlled camera moves and transitions.
- Advertising agencies – Teams producing brand blockbusters or product demos that require cinematic quality and consistent style across multiple shots.
- AI developers and integrators – Developers building applications that generate video from user prompts, needing a simple API with polling or webhook callbacks.
What can you do with Seedance 2.5 API?
- Generate storyboard visuals – Input a detailed textual storyboard (e.g., steampunk clockwork odyssey) and receive a 30-second cinematic video matching the described shots.
- Create match-cut sequences – Use a consistent subject (e.g., a crystal ball) and switch background scenes between each cut while keeping the subject in focus.
- Produce high-end brand content – Combine macro close-ups, slow-motion, and volumetric lighting effects for luxury product or fashion videos.
How does Seedance 2.5 API work?
The API is accessed via an EvoLink API key, obtained from the Evolink dashboard. Users send a request containing prompt text, optional image/video/audio references, duration, resolution, and a callback URL or polling preference. The API processes the job asynchronously and returns a video file once complete. The current request schema is available at the OpenAPI spec link on the homepage.
