Veo 3.1 Fast - Image to Video

Try Veo 3.1 Fast - Image to Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: google-veo-3-1-fast Veo 3.1 Fast is Google’s image-to-video model for generating short, high-fidelity videos from a single input image and a motion prompt. It supports natural motion, realistic scene animation, optional native audio generation, and controllable output settings such as duration, aspect ratio, and resolution (including 4k).

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
