Frequently Asked Questions

  • What improved in the Veo 3.1 generation over Veo 3.0?

    The 3.1 generation delivers improvements in motion physics accuracy, frame-to-frame object coherence, and audio-visual synchronization precision. In standard-quality mode, these improvements are most pronounced in scenes with complex motion or precise audio timing requirements.

  • How does the fast vs standard quality difference manifest in output?

    Standard Generate applies more generation compute per request, resulting in tighter frame consistency, more accurate motion physics, and better audio-visual alignment on complex scenes. For simple scenes, the difference may be minimal. The gap is most visible on content with fast motion, fine detail, or precise audio timing.

  • What audio generation capabilities does Veo 3.1 include?

    The model generates ambient environment audio, sound effects, and dialogue synchronized to visual events from text prompt descriptions. Audio and video are generated in a single pass without post-production audio assembly.

  • Does Veo 3.1 support image-to-video?

    Yes, provide a reference image alongside a text description to animate it. The model generates video that begins from the reference image with motion described in the prompt.

  • What resolution does Veo 3.1 support?

    Up to 1080p, with duration and aspect ratio options depending on the provider. See the Specs table on this page for the full list.

  • How do I use Veo 3.1 on AI Gateway?

    Use the identifier google/veo-3.1-generate-001 with the generateVideo interface in the AI SDK. AI Gateway handles provider selection and failover automatically.
