# Seedance 2

> The video engine behind Superscale. One storyboard becomes a full, multi-scene video with native audio.

Seedance 2 turns one storyboard into a complete generated multi-scene video. In supported English formats it can generate native spoken audio; non-English workflows use post-mixed voiceover.

In chat, Seedance output is currently **9:16 vertical**. Horizontal, landscape, and 16:9 generation are not supported in the chat video flow yet.

## Audio and storyboard rules

| Case                      | How the script is handled                                                                              |
| ------------------------- | ------------------------------------------------------------------------------------------------------ |
| **English native audio**  | Spoken lines belong inside the Seedance scene descriptions and are mirrored as the transcript.         |
| **Non-English voiceover** | Spoken copy lives in the voiceover field and is mixed in after render. Scenes stay visual and ambient. |
| **Captions**              | Captions are a post-processing layer, not text the video model should draw inside the scene.           |
| **End cards**             | End cards are generated or appended after the video, not storyboard scenes.                            |

<Note>
  Attach exact product, app, logo, packaging, and end-card assets when those details matter. Do not ask Seedance to recreate exact commercial details from memory.
