# Seedance 2.0 Fast

> Seedance for less, up to 15 seconds. The usual choice when you don't need 1080p or longer clips.

Source: https://docs.nocamclub.com/models/seedance-2.0-fast

- **Model id:** `seedance-2.0-fast`
- **Makes:** videos
- **From:** 18 credits ($0.18)
- **Routes:** 2

## Writing prompts

- Name every file and say what it's for. See [Files in prompts](https://docs.nocamclub.com/api/files-in-prompts.md).
- Audio needs a photo or a video next to it.
- `reference_mode: "frames"` sets the first and last frame.

## Good to know

- **Video among the files costs much more.** Those prices have `with_video: true`. All videos together: up to 15 s. Photos and audio files don't change the price.
- Reference videos showing a person may be refused as a real person, even when they're AI-made.
