Prompting Best Practices for Google Veo 3.1 API
Think of your Veo 3.1 prompt as direction for a video shoot. The clearer you are about what should appear, how it should move, how it should be filmed, and what it should sound like, the easier it is to get a polished result.
A Simple Prompt Formula
Scene + Subject + Action + Camera + Lighting + Style + Audio
What You Should Notice
Use clear camera language: Mention close-up, wide shot, drone shot, slow push-in, handheld follow, or tracking shot.
Describe the main action: Keep the scene focused on one strong movement or event.
Add lighting and mood: Words like golden hour, neon-lit, soft studio light, dramatic, playful, or suspenseful help shape the result.
Specify audio: Include ambience, dialogue, music, sound effects, or silence instead of letting the model guess.
Use references when needed: Add reference images for products, characters, or brand visuals when visual accuracy matters.
Example Prompts
Product Launch Video
“A cinematic product launch video of a matte black wireless headphone floating above a reflective glass surface. Soft studio lighting, slow rotating camera movement, subtle blue highlights, premium tech commercial style. Add deep ambient music and a soft electronic whoosh as the product turns toward the camera.”
Fashion Brand Teaser
“A stylish model wearing a beige trench coat walks through a rainy city street at night. Neon signs reflect on the wet pavement, the camera follows from a low angle, slow-motion movement, luxury fashion campaign mood. Include soft rain ambience and quiet cinematic music.”
Character Story Scene
“A young astronaut stands alone on the surface of a red desert planet, looking at a distant glowing city on the horizon. Wide cinematic shot, dust moving in the wind, dramatic sunset lighting, slow camera push-in. Add low atmospheric wind and emotional orchestral music.”
First-to-Last Frame Transition
“Start with a closed luxury perfume box on a marble table. End with the bottle fully revealed, standing upright with golden light reflecting through the glass. Generate a smooth cinematic reveal between the two moments, elegant camera movement, premium beauty ad style, soft sparkling sound effects.”
