Write the First Frame To Last Frame AI endpoint contract

Describe the action linking the images with ordered verbs and visible checkpoints. Preserve the screen axis and state explicitly whether the camera follows, remains locked, or arrives independently. Inventory source rights for both images and mark any identity, product, text, or location detail that cannot change. Endpoint control is meaningful only when the transition has a defined editorial job and the two supplied states are compatible enough to review. For a reversible workflow, preserve the failure note, and ask the continuity editor to record visible continuity before the rights check.

Inspect the path, not only the two supplied images

Use a hand placing an object as the transition: empty table at the start, placed object at the end, with fixed camera, lighting, hand identity, and contact point. Review intermediate frames at a consistent cadence for geometry, identity, contact, lighting, camera axis, and causal order. A model can reproduce the beginning and ending while inventing an unusable bridge, so acceptance belongs to the whole shot rather than two thumbnails. For a reversible workflow, preserve the brief version, and ask the workflow owner to record revision intent before the evidence refresh.

• Opening-state fidelity For the working record, preserve the authorization record, and ask the source custodian to record temporal order before the dated decision.
• Causal intermediate motion For the working record, preserve the failure note, and ask the policy reviewer to record revision intent before the dated decision.
• Closing-state and edit usability For the working record, preserve the evidence table, and ask the creative lead to record input provenance before the dated decision.

Separate capability, availability, and entitlement

The path is not acceptable when the object appears without contact, the hand changes, timing hides the action, or the model reaches the destination through an unintended camera cut. Verify the exact vendor, model version, region, account surface, input constraints, and check date before relying on the feature. The documented Veo example proves a named control in that context; it does not prove current SEELE access or any free, downloadable, permanent, or open-ended use. For the working record, preserve the continuity note, and ask the accessibility reviewer to record control availability before the dated decision.

Keep the First Frame To Last Frame AI evidence ledger narrow

Google DeepMind first-party documentation verifies a current first-and-last-frame control for Veo 3.1. Record the source owner, product or model name, verification date, surface or region, exact claim, and unresolved gap beside the test. Taxonomy eligibility and search demand explain why the page exists, but neither can be reused as proof that SEELE or another provider exposes the entire query as a current capability. For a controlled test, preserve the continuity note, and ask the identity reviewer to record temporal order before the bounded test.

• Google DeepMind lists first and last frame among the documented creative controls for Veo 3.1. For a controlled test, preserve the failure note, and ask the brand reviewer to record identity consent before the bounded test.
