Seedance 2.5 Image to Video

ByteDance's next-generation image-to-video model — transforms a still image into a native clip up to 30 seconds with continuous, coherent motion, native audio, and director-level camera control.

Highlights

Native 30-second animation — Extend a single frame into a long, continuous take without drift or stitching.

Native audio generation — Automatically creates synchronized sound effects, ambient audio, and lip-synced speech. Toggle with generate_audio parameter.

Start + end frame control — Provide both a starting image and an optional end image to precisely control video transitions and motion direction.

Flexible duration — Generate 4 to 30 second clips in a single request.
