Key Features Explained
Native Audio
Veo 3.1 generates synchronized audio with your video. Ambient sounds, effects, and atmospheric audio are created to match the visual content. No need to source stock audio or manually sync - the model handles it.
Reference Images
Upload images to guide the video generation:
- Style reference (match the aesthetic of an existing image)
- Subject reference (include specific objects or scenes)
- Brand assets (maintain visual consistency)
This is powerful for brand consistency across video content.
Frame Interpolation
Creates smoother motion by generating intermediate frames. Results in more fluid, professional-looking video with less of the "AI jitter" that plagues some generators.

Using Reference Images
Upload 1+ images to influence generation:
Style matching
"Generate a video in the exact visual style of the uploaded image. Same colour grading, similar composition, matching mood."
Subject inclusion
"Include the product shown in the reference image. Rotate it slowly against a minimal background."
Brand consistency
"Use the brand colours and aesthetic from the uploaded images. Create a short animated logo reveal."
Audio Tips
Native audio generation works best when you:
Describe the sound environment
- "Quiet café ambience with soft jazz"
- "Forest sounds - birds, rustling leaves"
- "Urban street noise - traffic, footsteps"
Specify audio mood
- "Upbeat, energetic electronic music"
- "Calm, meditative ambient tones"
- "Dramatic orchestral swell"
Request silence when needed
"No audio" or "Silent video" if you plan to add your own soundtrack.
