Seedance V2.0 vs Vidu Q3

Seedance V2.0 and Vidu Q3 differ on 8 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 V2.0 returns synced audio and Vidu Q3 does not, which decides most jobs. Vidu Q3 is cheaper at entry and offers a 360p tier, making it the better model for cheap composition passes.

The decisive fact is audio. Seedance V2.0 can return sound synced to the picture; Vidu Q3 cannot. For dialogue, or an effect that has to land on an action, that ends it.

Where audio is irrelevant, Vidu Q3 is the more economical model with a wider low end: 360p, 540p, 720p and 1080p from 10 credits, and durations from 1 to 16 seconds. Seedance V2.0 covers 480p to 1080p from 15, at 4 to 15 seconds.

The very low tiers on Vidu are more useful than they sound — at 360p you are testing whether the composition and the motion work, not the detail, and it is the cheapest way to find that out. Vidu Q3 Turbo takes the same range from 5 credits if cost is the binding constraint.

Pick Seedance V2.0 when

  • The clip needs sound tied to the picture — Vidu Q3 returns none.
  • You are conditioning on a reference clip or motion style.
  • The shot is the one that carries the sequence.

Pick Vidu Q3 when

  • You want the lower entry price — 10 credits against 15.
  • You want a 360p or 540p tier for very cheap tests; Seedance's cheapest is 480p.
  • The clip needs to run to 16 seconds, marginally past Seedance's 15.
