Pro Tips for Veo 3.1
Master Veo 3.1's cinematic generation with these expert techniques.
#1Write Cinematic Scene Descriptions
Structure prompts like screenplay scene descriptions: establish the setting, describe the action, and specify the camera movement. 'Aerial establishing shot of a coastal village, camera slowly descending toward the harbor as fishing boats return at sunset' produces dramatically better results.
#2Specify Audio Requirements in Your Prompt
Since Veo 3.1 generates audio natively, describe the soundscape you want: 'gentle waves lapping against the shore, seagulls calling in the distance, soft acoustic guitar music.' Being specific about audio yields much better synchronized sound.
#3Use Image-to-Video for Consistent Characters
Generate a character reference image first, then use image-to-video mode to animate it. This ensures character consistency across multiple video clips — essential for storytelling sequences.
#4Control Pacing with Duration Keywords
Use pacing keywords in your prompt to influence the video's rhythm: 'slow and contemplative,' 'fast-paced action sequence,' or 'gradual reveal.' Veo 3.1 adjusts its motion generation to match the described energy level.
