- Image-to-video prompts should focus on describing the motion of the scene.
Run this prompt
Copy the JSON above, then paste it as your prompt in any of these tools. Veo 3.1 is free to try inside Gemini (daily limit applies).
What each block does
| Block | Purpose |
|---|---|
| references | Optional image inputs: product, character face, or style frame. Use these where the model supports references; otherwise treat them as setup notes. |
| brand | Brand constraints: colors, logo handling and voice. Models approximate hex colors and cannot render exact logos reliably; use a reference image or add exact logos in post. |
| scene | Where it happens: location, time of day, weather, mood of the space. |
| subject | Who or what the shot is about. Keep it to one clear subject — models blur focus when given several. |
| action | What visibly happens during the clip. Describe motion the camera can see, not internal states. |
| camera | Shot framing and movement. One movement per clip reads best on every current model. |
| lighting | Light source, quality and shadow behavior. The single highest-leverage block for realism. |
| style | Aesthetic direction: film stock, color palette, references, tone. |
| audio | Dialogue, ambient sound and music. Only Veo 3.1, Kling 3.0 and Seedance 2.0 render audio natively. |
| technical | Render settings: aspect ratio, duration, fps, seed for reproducibility, negative prompt. |
