Veo 3.1 First & Last Frame Guide

First and last frame control is most useful when the frames are treated as production anchors: the first establishes the exact starting state and the last defines where the shot should resolve.

How GenVideoKit structures Veo 3.1 prompts

Use coherent natural-language direction with explicit temporal flow from start state to end state. Describe subject action, camera behavior, lighting and environmental motion. When relevant, integrate dialogue, ambience and sound effects because this model family supports native audiovisual generation. Avoid conflicting camera moves and keep continuity physically plausible.

Production shortcut

Treat the first frame as the exact start state and the last frame as the intended resolution. Keep identity, screen direction and environment consistent between them.

First frame

Use a clean starting state with readable subject pose, environment and screen direction. Avoid an ambiguous pose that already looks mid-transition unless that is intentional.

Last frame

Define a stable end state that can also become the next clip’s reference. The cleaner the final subject pose and environment, the easier it is to continue the sequence.
