30-Second ByteDance AI Video with Native Audio

Seedance Video 2.5 renders up to 30 continuous seconds natively, so a full ad beat, product story, or narrative moment holds together without stitching clips or fighting drift between segments.
Attach up to 30 images, 10 videos, and 10 audio tracks, then address them in the prompt as @Image1, @Video1, and @Audio1 to lock characters, props, motion style, and sound across the whole runtime.
Sound is generated with the picture in the same pass, so ambience, effects, and pacing stay in sync from the first frame to the thirtieth second instead of drifting apart in post.
Build long-form AI video by pairing scene-length prompts, @-mentioned references, audio direction, and short draft passes.
A 30-second render wants a scene, not a moment. Describe the setup, the movement, and the resolution, plus lens, lighting, audio cues, and what to avoid, so the model has direction for the whole runtime.
Upload the character frames, product stills, motion clips, and audio beds you want honoured, then call each one by name in the prompt so the model knows which reference governs which part of the scene.
Test the creative direction at 4 to 8 seconds, then re-run the winning prompt at full length once the framing, motion, and audio read the way you want.
