Veo 3.1 Extension allowlist request

Hello!

Our Google Cloud project: zavod-veo-service (ID: zavod-veo-service).

We’re trying to use the Extension (video-to-video / scene extension) feature in Veo 3.1 via the API (predictLongRunning), but receive this error:
“Async process failed with the following error: Video extension is not allowlisted for project zavod-veo-service.”

  • Billing is active in our account
  • Using official endpoint in us-central1 region
  • Veo 3.1 basic generation works fine
  • We use Extension for creative video prototyping and R&D scenarios

Could you please add our project (ID: zavod-veo-service) to the allowlist for the Extension (video-to-video) feature in Veo 3.1 on Vertex AI?

We’re happy to provide additional details and use case information if needed.
Thank you!
