Kenning's take

What it does

Veo 3.1 is Google's video generation model, building on Veo 3 with richer generated audio, closer prompt following and more realistic textures. In Google's Flow filmmaking tool it powers features that use reference images, first and last frames, and clip extension, all with sound. It is also available in the Gemini app, through the Gemini API and on Vertex AI.

  • Video with generated audio
  • Ingredients to Video using reference images
  • Frames to Video from a start and end image
  • Extend clips to a minute or more
  • Fast and Lite variants on the Gemini API

Who it suits. Filmmakers, marketers and developers who generate short video clips from text or images.
