Seedance V1.0 Pro vs Seedance V1.5 Pro

Seedance V1.0 Pro and Seedance V1.5 Pro differ on 2 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?

Seedance V1.5 Pro adds synced audio, which V1.0 Pro does not have, and starts cheaper at 3 credits against 5. There is no reason to start new work on V1.0 Pro.

Both cover 480p, 720p and 1080p. V1.0 Pro takes 2 to 12 seconds from 5 credits and returns no audio. V1.5 Pro takes 4 to 12 seconds from 3 credits and can return synced audio.

The newer model is therefore cheaper at entry and adds a capability the older one lacks entirely. That is an unusually clean upgrade — normally a newer release costs more.

The only thing V1.0 Pro still does that V1.5 Pro cannot is very short clips: 2 and 3 second durations, where V1.5 Pro starts at 4. If you are cutting fast montage material at two seconds a shot, that is a genuine reason to keep it. For everything else, V1.5 Pro supersedes it.

Pick Seedance V1.0 Pro when

  • You are matching shots in a sequence already generated on V1.0 Pro.
  • You need durations from 2 seconds; V1.5 Pro starts at 4.

Pick Seedance V1.5 Pro when

  • Anything new — it adds audio and costs less at entry.
  • The clip needs synced sound at all.
  • You want the newer generation's output within the same resolution range.
