About Seedance 2.0 Fast
Seedance 2.0 Fast is the fast tier of ByteDance's Seedance 2.0, priced at $0.27 per second. It keeps the Seedance 2.0 modes, text to video, image to video, start and end frame and references to video, with sound generated with the video, at 480p and 720p and 16:9, 9:16, 1:1, 4:3, 3:4 and 21:9, from 4 seconds to 15 seconds.

Good for
- Seedance 2.0 references at a lower rate, with audio clips as well as images
- Drafts at 480p before a final render
Getting good results
- In reference mode the provider reads tags in the prompt:
@Imageand@Audio, each with its number in upload order. - Reference images can be JPEG, PNG, WebP, BMP, TIFF, GIF, HEIC or HEIF; audio clips MP3 or WAV. Audio clips need an image alongside them.
- Leave audio on: the provider charges the same whether sound is generated or not.
