Why Veo 3.1 leads the field
Google DeepMind's most advanced video model — the one that made native audio and true cinematic control standard.
Native Synced Audio
Veo 3.1 generates the soundtrack together with the picture — dialogue, ambient sound, and effects locked to the action. No separate audio pass, no lip-sync drift.
Cinematic Camera Control
Understands directorial language — dolly, pan, crane, rack focus. Describe the shot the way a cinematographer would and Veo 3.1 renders it.
First & Last Frame
Give Veo a start frame, or a start and end frame, and it animates the motion between them — ideal for product reveals and controlled transitions.
Up to 4K Output
Render at 720p, 1080p, or true 4K. Native 16:9 widescreen and 9:16 vertical for social, all at 8 seconds.
Reference-Guided Generation
Feed up to 3 reference images to lock character, style, or composition across the clip on the Fast tier.
Two Official Tiers
Veo 3.1 Fast for quick iteration, Veo 3.1 Quality for final delivery — both official Google DeepMind channels, both with native audio.
From prompt to cinematic clip in under 2 minutes
Veo 3.1 works like a film crew that never sleeps — describe the scene, it shoots and scores it.
Describe your shot
Write the scene, the camera movement, and the sound you want. Add a reference image for image-to-video. Veo understands natural cinematic language.

Prompt writing guide for Veo 3.1
Veo 3.1 rewards specific, cinematic direction — and it can generate audio, so describe sound too.
Direct the picture and the sound in the same prompt
Lead with subject and action
Open with who or what is on screen and what they do. Veo 3.1 anchors the whole clip on a clear main subject.
- •Name the subject in the first few words
- •Give one clear action per clip
- •Keep it to a single continuous moment — you have 8 seconds
Example
"A weathered fisherman hauls a net over the side of a small boat at dawn."
Direct the camera
Veo understands real cinematography terms. Specify the move and the framing to control the feel.
- •Use terms like dolly in, slow pan, crane up, rack focus
- •State the shot size: wide, medium, close-up
- •One camera move per clip reads cleaner
Example
"Slow dolly-in on the fisherman's face, shallow depth of field, golden backlight."
Describe the sound
This is Veo's superpower — it generates synchronized native audio. Spell out dialogue, ambience, and effects.
- •Put spoken lines in quotes for dialogue
- •Name ambient sound: waves, wind, distant gulls
- •Mention key sound effects tied to the action
Example
"Ambient: gentle waves and creaking rope. He mutters, "Almost there.""
Set lighting and mood
Light defines the emotion. Veo 3.1 renders time of day, weather, and color grade faithfully.
- •Name the time of day and light source
- •Add a mood word: serene, tense, nostalgic
- •Reference a look: cinematic, documentary, film noir
Example
"Golden hour, warm rim light, soft haze — serene and cinematic."
Lock a visual style
Pin the aesthetic so the clip matches your brand or reference. Fast tier also accepts up to 3 reference images.
- •Name a genre or era for consistency
- •Add lens hints: 35mm, anamorphic, macro
- •On the Fast tier, attach reference images for character or style
Example
"Shot on 35mm film, muted teal-and-amber grade, subtle grain."
Choreograph the motion
Because clips are 8 seconds, plan one clean arc of motion rather than many events.
- •Describe how the subject or camera moves through the shot
- •Avoid cramming multiple scene changes into one clip
- •For transitions, use first-and-last-frame image-to-video instead
Example
"The boat drifts left to right across frame as the sun climbs, a single unbroken take."
