FAQ

What is the difference between Veo 3.1 Lite and Veo 3.1 Fast?

Veo 3.1 Lite is text-to-video only and does not support reference images, frames-to-video, or audio generation. Veo 3.1 Fast supports image-to-video, ingredient (frames) mode, up to 3 reference images, and native AI audio. See the playground for current pricing on each tier.

Can I use image_urls with Veo 3.1 Lite?

No. The image_urls parameter is not supported by veo3.1-lite. For image-to-video generation, use veo (Veo 3.1 Fast) instead.

Why does my video have a watermark?

All videos generated with Veo 3.1 models (Fast and Lite) include a visible watermark per Google DeepMind’s policy for third-party API providers.
