Where this family fits.
Preparing a bounded Veo 3.1 shot brief
Checking 8s, 720p and auto / 16:9 / 9:16 before you run
Cuts that already fit a fixed 8-second Veo 3.1 clip
Deliverables that expect Veo 3.1 to render its own audio track
Anchoring a Veo 3.1 shot to one or two reference images
What not to assume.
Duration, resolution, audio and reference support differ across Veo 3.1, Veo 3.1 Fast, Veo 3.1 Lite, so the figures above are the family union rather than one policy.
Veo 3.1 always renders its own audio; the catalog lists no silent Veo 3.1 policy.
Motion can drift in identity, geometry, small text, logos and continuity, so Veo 3.1 output still needs review before publishing.
A Veo 3.1 request is asynchronous: a pending job is not a finished clip.
What the Veo 3.1 envelope allows
Veo 3.1 currently lists 8s durations, 720p output and auto / 16:9 / 9:16 aspect ratios. Length is fixed at 8 seconds, so the edit is planned around one cut rather than trimmed afterwards.
Choosing the workflow
Veo 3.1 starts from a prompt alone or from a reference image, so the first decision is which of the two carries the framing. Up to 2 reference frames are accepted per request. Audio is rendered natively with the clip rather than added later.
How a request runs
Vizify inspects the selected policy before it sends the request, so a value outside the published envelope is refused rather than quietly adjusted. Video generation is asynchronous: a pending job is not a completed artifact, and the returned clip still needs a review pass for identity, geometry, small text and continuity before it is published.
