Seedance 2.5

Protoface offers the Seedance 2.5 API cheaper than BytePlus. Seedance 2.5 is ByteDance's video model for generating scenes and developing existing visual material through animation, editing, and extension. Images, video, and audio can guide the creative direction, with generated sound accompanying the picture.

The reference workflows are useful when a shot has an established character, product, or atmosphere. Editing gives existing footage a written direction for changes, while extension carries its action into additional footage.

What it's good for

Brand films, narrative sequences, and trailers can use these modes at different stages of production. A team can begin with artwork or a scene brief, then refine and continue the resulting footage as part of a larger edit.

Run Seedance 2.5 on Protoface

Use Seedance 2.5 in Protoface Studio without writing code. Choose your inputs and generation settings, then generate with affordable, usage-based pricing. For your own AI app or workflow, use the Protoface API to submit generations and retrieve their outputs.
