Veo 3.1

google/veo3.1/extend-video continues existing footage beyond its ending while carrying forward motion, subjects, camera behavior, and scene context. Veo 3.1 improves instruction following, physical consistency, character continuity, and audiovisual quality while supporting more ways to anchor or continue a shot. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.

For production work with google/veo3.1/extend-video, the video continuation workflow suits storyboards, campaign films, product moments, narrative shots, and visual concepts that need coherent motion rather than isolated animated frames. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.

Highlights

Seam-aware continuation extends source footage while preserving movement and scene identity.

Improved physical coherence strengthens object interactions, character movement, and cause-and-effect across shots.

Visual continuity maintains subjects and scene logic across the generated sequence.

Native audio generation coordinates dialogue, ambience, and sound effects with the visual action.

Prompt Guide

For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
