Generate broadcast-ready video clips with synchronized dialogue, sound effects, and music. Seedance 1.5 Pro generates all from a single text prompt. Seedance 1.5 Pro uses a dual-branch diffusion transformer to render video and audio in the same latent space, producing tight lip-sync and natural foley without post-production.

| Feature | Description |
|---|---|
| Native audio generation | Dialogue, sound effects, and ambient audio generated alongside video. Lip movements stay locked to speech; foley stays locked to action. |
| Cinematic camera work | Full camera grammar: pan, tilt, zoom, dolly, orbit, tracking shots, rack focus. Describe the move in your prompt and the model executes it. |
| Character consistency | Faces, clothing, and expressions stay stable across the clip, even when camera distance or angle changes. |
| Narrative coherence | The model understands story beats: it can hold emotional arcs, maintain scene logic, and keep multi-character blocking consistent. |
| High resolution | Output up to 1080p at 24 fps with smooth temporal consistency. |

Anchor your video with specific start and end frames. Upload reference images to define the opening and closing compositions — the model generates all the motion, camera movement, and audio in between.
