What it is good at

ByteDance describes Seedance 2.5 as joint audio-and-video generation for one-take storytelling: several connected shots in a single clip, with smoother motion and a more finished look than a loop of one gesture. Sound is part of that generation when you ask for it.

How to use it on Visxy

Write the shot. Turn sound on if you want it. Give one picture as the opening frame and an optional second as the closing frame.

Where it differs

Seedance 2.0 Fast is the fast model in the Seedance 2.0 line, up to 720p and 15 seconds, and it still needs a prompt when you start from frames. Seedance 2.0 Mini is the smaller Seedance model, with the same kind of prompt, frames, and sound switch.

FAQ

Can I set the first and last frame?

Yes. One picture opens the clip, and a second can close it.

Is there sound?

Yes. The switch starts off until you turn it on.

How is Seedance 2.0 Fast different?

Seedance 2.0 Fast is the fast Seedance 2.0 model. It stays at 720p and 15 seconds, and a prompt is still required when you add an opening frame and an optional closing frame. Seedance 2.5 reaches 1080p and 30 seconds, and it can start from a single frame without a prompt.
