API documentation
Explore Seedance 2.5 API capabilities
Plan the shot, bring the right references, and choose how you want to finish it. These illustrated workflows explain the controls available through Seevio.
Create longer scenes with Seedance 2.5 API
Seedance 2.5 API supports 4–30 seconds of output, giving a product reveal or character moment time to develop. Describe the opening, the action and the ending in one prompt; add camera direction and timing where they matter. For a launch film, introduce the product, show it in use and finish on a clear composition rather than squeezing every beat into a short loop.

Render native 1080p video with Seedance 2.5
Choose 480p for exploration, 720p for balanced iteration or 1080p for detailed delivery. Seedance 2.5 API makes resolution an explicit request parameter, so your application can offer quality options alongside its cost estimate. Product textures, lighting and close-up framing deserve a careful review at the chosen output size before a clip becomes part of a campaign.

Guide Seedance 2.5 API with images, motion and sound
Combine up to 30 images, 10 videos and 10 audio files, within a total of 50 reference assets. Assign each input a purpose: a product image for appearance, a location image for atmosphere, a video for movement and audio for sound direction. Seedance 2.5 API accepts these references in a shared request. Keep total reference-video duration and total reference-audio duration within 30 seconds each.

Refine scenes with Seedance 2.5 API
Use reference-guided editing to describe what should change and what should remain. Identify the subject, location or time interval precisely, and provide source footage with the visual context the edit needs. Seedance 2.5 API supports editing and extension workflows; a specific brief helps you evaluate the result against the source instead of starting every iteration with an unrelated concept.

Preview in 480p and finish in 1080p with Seedance 2.5
Try a composition as a 480p Draft, review the result, then submit its completed task ID for a 1080p final. Seedance 2.5 API retains the original prompt, references, duration and audio settings for this finishing step. An API Draft must belong to your account and be less than seven days old from creation. The final is a new, separately billed task; you can choose which preview deserves that extra render.

More control with Seedance 2.5 API
See how reference-driven creation translates into motion. These model examples illustrate creative possibilities; the images above explain the workflow.

Carry visual intent into the shot
Use references to communicate appearance, composition and motion together. Build a concise brief that assigns each material a role and explains which visual relationships matter.

Plan camera movement and staging
A clay-render reference can communicate spatial layout and camera direction. Submit it as reference material with a description of the finished look, then inspect framing and movement in the result.

Guide a focused visual change
Reference-based editing is useful when a scene already has a clear direction. Describe the change, specify what to retain and compare the output with the original composition.

Seedance 2.5 API and Seedance 2.0 API
Choose a model around the required duration, reference set and workflow. These are the settings supported by Seevio, rather than a subjective quality score.
| Capability | Seedance 2.5 | Seedance 2.0 |
|---|---|---|
| Output duration | 4–30s | 4–15s |
| Resolution | 480p / 720p / 1080p | 480p / 720p / 1080p / 4k |
| Image / video / audio references | 30 / 10 / 10 | 9 / 3 / 3 |
| Combined reference limit | 50 | 12 |
| Total reference video / audio duration | 30s / 30s | 15s / 15s |
| Draft to final workflow | 480p → 1080p | — |
Model-specific limits still apply to individual files and generation modes. The API documentation contains the complete validation rules.

Can I try Seedance 2.5 API without writing code?
Yes. Use the generator at the top of this page to try prompts, reference assets and video settings without writing code. The generator uses your website account and credits; API requests require an API key and follow the API billing workflow.
Does Seedance 2.5 API support 30-second 1080p videos?
Yes. Seedance 2.5 API supports durations from 4 to 30 seconds and output at 480p, 720p or 1080p. Choose a supported duration and resolution in your request. Draft previews are limited to 480p, while Draft finals use 1080p.
How many references can I include?
You can provide up to 30 images, 10 videos and 10 audio files, with a combined maximum of 50 materials. Reference videos must total no more than 30 seconds, and reference audio must also total no more than 30 seconds. File and mode restrictions are documented separately.
How does the Draft workflow work?
Create a task with draft enabled, wait for it to complete, then submit its task ID as draft_task_id for a 1080p final. Use an API Draft owned by your account within seven days of creation. The final inherits the creative inputs and is billed separately.
How is Seedance 2.5 API usage billed?
Billing depends on the operation, resolution and duration. Reference video can add billable input seconds. Credits are reserved at submission, with adjustments and refunds according to the task outcome. Check the model documentation for current rates before estimating production usage.
Should I poll for results or use a callback?
Polling is straightforward for a first integration. A callback can notify your server when a task reaches a terminal state. Verify notifications against the authenticated task endpoint and make your handler safe for repeated events.
