Veo 3.1 Extend
Veo 3.1 Extend is a video continuation capability from Google that takes an existing video clip and generates a coherent extension of it. Rather than creating a video from scratch, it analyzes the motion, style, scene, and content of the provided footage and produces additional seconds that flow naturally from the ending frames.
This is valuable in both creative and production contexts—editors can lengthen short clips, creators can iterate on generated video by extending promising takes, and filmmakers can bridge gaps in footage. The model maintains continuity of lighting, camera motion, and subject behavior throughout the extension.
