Veo 3.1 Reference Image Guide
A reference image should tell the model what already exists. Your text should then explain what changes over time instead of redundantly redescribing every visible detail.
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
Let the image define the starting appearance. Use the text to define motion, camera behavior and the elements that must remain locked.
Good reference frame
- Subject is readable and not heavily occluded.
- Pose leaves room for the intended motion.
- Important product or identity details are visible.
- Lighting direction and environment are coherent.
- The frame already resembles the intended starting composition.
Prompt what changes
Do not spend the prompt redescribing everything already visible. State the motion, camera move, final state and the details that must not drift.
