Introducing Seedance 2.5 support

AI Animation now supports Seedance 2.5 for enabled workspaces as part of a limited rollout. The integration adds longer clips, much larger multimodal reference sets, and dedicated Create, Edit video and Extend video task modes.

What has changed

Choose Seedance 2.5 from the video model picker and select the task that matches the job:

• Create generates a new clip from your prompt, with optional reference assets.
• Edit video uses an existing clip as the source anchor for a newly generated result.
• Extend video continues a source clip forward or backward.

Seedance 2.5 accepts image, video and audio references, as well as production components already stored in your project. This makes it easier to keep more of the visual and audio context for a shot together inside one generation workflow. Video references share a 30-second combined duration budget; audio references have a separate 30-second combined budget.

Seedance 2.5 compared with Seedance 2.0

The practical advantage of Seedance 2.5 is not simply a higher version number. It is better suited to longer shots, reference-heavy briefs and workflows where you want to modify or continue an existing clip. Seedance 2.0 remains useful, where available, when the 4K output route is important to the job.

Using Edit and Extend

Open Create inside a project folder, switch Shot Director to Video, and select Seedance 2.5. For Edit video or Extend video, place the source clip in Video 1 and use the Adaptive aspect ratio. Edit video also requires Automatic duration.

If Seedance 2.5 is missing from your model picker, your workspace may not yet have access or its model policy may exclude it. Provider availability also applies. References depicting real people—whether images or video—may require additional Seedance setup, likeness authorisation and approved BytePlus assets.

Credit estimates vary with output duration, resolution, aspect ratio and total reference-video duration. Check the live credit indicator before generating.
