Seedance 2.0 Fast
Seedance 2.0 Fast keeps the Seedance multimodal workflow but prioritizes speed and lower-resolution draft work. Use it when you need to test references, motion, or audio direction before committing to the standard model.
Best for
- fast video drafts
- reference tests
- audio-guided drafts
- iteration
Use when
- You want to test a multimodal setup quickly.
- You need a cheaper or faster pass before the final Seedance run.
- The prompt uses frames or references but final quality is not required yet.
Avoid when
- You need maximum Seedance output quality.
- You need a source-video edit flow; use Seedance 2.0 standard where DayGen exposes edit support.
