Seedance 2.0 Fast at a glance

Seedance 2.0 Fast sits between the full 2.0 model and 2.0 Mini. It keeps the 2.0 feature set — six aspect ratios, image and reference inputs — while dropping 1080p and 4K, which makes it a solid everyday pick for social-resolution B-roll.

Why pick Seedance 2.0 Fast in Shorz

Built for social resolution

720p is what TikTok, Reels and Shorts actually display. Fast renders exactly that, without paying for pixels the feed throws away.

Same inputs as 2.0

Text, a still image or a set of references — up to 9 images, 3 videos and 3 audio clips.

Cheaper than 2.0 per second

A lower per-second rate than the full model at the same resolution, so you can try more takes for the same budget.

Best for

  • Social B-roll
  • Explainer scenes
  • Draft passes
  • Vertical shorts

Seedance 2.0 Fast questions

Fast renders 480p or 720p at a lower price per second; the full 2.0 model adds 1080p and 4K. Lengths (4–15s), aspect ratios and reference inputs are the same.

Mini is the cheapest video model in Shorz and the default; Fast costs a little more per second. Both stop at 720p and 15 seconds.

No. Shorz never watermarks output, and you keep full commercial rights.
