Veo 3.1, Fast and Lite

Choose the variant for the task.

Veo 3.1 is Google’s video family with native audio and frame-directed generation. Standard, Fast and Lite are separate choices; the name alone doesn’t tell you the speed, price or inputs.

A focused starting point.

Decide whether you are starting a new clip or continuing one. For a new scene, begin with one action; for an extension, check the ending you want to continue and describe the next beat.

  1. In AIFACECRAFT

    In AIFACECRAFT, Veo 3.1 and Veo 3.1 Fast accept reference inputs and can extend a clip. Veo 3.1 Lite takes first and last frames but doesn’t offer references or extension. Some choices fix the length: references, a last frame or 1080p use 8-second clips, and an extension adds 7 seconds at 720p. Check the panel after switching variants.

  2. Review Before You Continue

    Check water behaviour, the boat’s shape and sound. For an extension, review the join and the transition in motion and lighting.

A few useful answers.

Can I use Lite for the same extension task?

No. Lite has no extension mode in AIFACECRAFT; choose Veo 3.1 or Veo 3.1 Fast.

What should I check before using a result?

Check water behaviour, the boat’s shape and sound. For an extension, review the join and the transition in motion and lighting.

Take the next step in Studio.
