Seedance V2.0 vs Seedance V2.0 Fast

Seedance V2.0 and Seedance V2.0 Fast differ on 6 specifications — from what each one costs to which inputs it accepts. Every value below is read from the live model catalog, so it stays current as new versions ship.

Which should you use?

Fast is the iteration tier: same 4-to-15-second range and synced audio, but capped at 720p and priced from 12 credits against 15. Use Fast until the shot is settled, then run the full model if you need 1080p.

The two models share the duration range (4 to 15 seconds) and both can return synced audio. The differences are the resolution ceiling and the price band: Seedance V2.0 covers 480p, 720p and 1080p from 15 to 65 credits, while V2.0 Fast covers 480p and 720p from 12 to 25.

The price ceiling is the more interesting number. A full-model take at 1080p can cost 65 credits; Fast cannot exceed 25 whatever you ask of it. For exploratory work where you are running many takes, that cap is worth as much as the entry price.

The decision reduces to your delivery resolution. If 720p is where the clip ends up, Fast is the same model with the same reference conditioning and no meaningful compromise. If you need 1080p, only the full model can produce it.

Pick Seedance V2.0 when

  • The clip is being delivered at 1080p — Fast stops at 720p.
  • It is the final take and worth the higher ceiling.

Pick Seedance V2.0 Fast when

  • You are exploring and want more attempts per credit.
  • 720p covers the delivery, which it does for most social and web use.
  • You want the top of the range capped — Fast tops out at 25 credits against 65.
