What is the Seedance 2.5 API?

Seedance 2.5 is ByteDance's next-generation audio-video model for creators who need longer clips, precise motion, native sound, and high-resolution delivery.

The family supports text-to-video, image-to-video, first/last-frame transitions, multi-modal omni reference, video editing, and video extension. A single request can use up to 30 images, 10 videos, and 10 audio files as references.

Muapi provides 72 variants through one asynchronous REST contract, with standard, International, and Spicy options priced by generated second.

First and last frame keyframes

Set the start and end images to guide controlled transitions and shot continuity.

Omni reference generation

Combine up to 30 images, 10 video clips, and 10 audio files to guide style, identity, motion, and mood.
