Meet Seedance 2.0 Fast
Seedance 2.0 Fast runs ByteDance's Seedance 2.0 on a quicker, cheaper route. It keeps the full input set: text, a start and end frame, or up to four reference images of your product, with sound generated alongside the picture.
It renders at 480p or 720p. For most social placements that is all you need, which makes Fast the tier to use day to day and the place to settle a prompt before a 1080p render on Seedance 2.0.
