Veo 3.1 Fast
Veo 3.1 Fast keeps the Veo family workflow but trades some quality headroom for speed. Use it to explore cinematic prompts, image-to-video setups, or Veo-native audio direction before choosing a final pass.
Best for
- fast Veo drafts
- cinematic iteration
- native audio tests
- I2V previews
Use when
- You want to test a Veo prompt quickly.
- You need a faster pass before running standard Veo.
- The concept is still exploratory but you want Veo's motion language.
Avoid when
- You need maximum Veo quality; use Standard.
- You need source-video editing or long source continuity.
