What is Veo 3.1
Veo 3.1 is Google DeepMind's flagship video generation model, distinguished by an industry-first capability: native audio generation. While other AI video generators produce silent clips, Veo 3.1 creates complete audiovisual experiences with synchronized dialogue, sound effects, and ambient audio.
The model generates video at 720p-1080p with upscaling to 4K for professional workflows. Motion quality matches cinematic standards with smooth camera movements and natural visual coherence. The 24fps output provides film-like smoothness for professional applications.
Veo 3.1 represents Google's comprehensive approach to AI video, combining their expertise in visual generation, language understanding, and audio synthesis. The result is a production-ready tool for creating complete video content without separate audio production.
Native Audio Generation
Veo 3.1's native audio capability transforms AI video generation from visual-only to complete audiovisual production.
Dialogue with Lip-Sync
Generate natural speech synchronized with on-screen characters. The model produces dialogue with accurate lip-sync, creating believable speaking characters. Conversations, narration, and character speech integrate naturally with visual content.
Include dialogue in your prompts to generate speaking characters. Describe who speaks and what they say. The model handles synchronization automatically, matching mouth movements to generated speech.
Sound Effects
Synchronized sound effects match on-screen actions and events. Footsteps, doors, impacts, mechanical sounds, and other effects generate in sync with visual elements. The temporal alignment creates coherent audiovisual experiences.
Sound effects add production value without separate audio work. Actions that would require foley recording in traditional production generate automatically with matched timing.
Ambient Audio
Environmental background audio creates atmosphere and immersion. Indoor spaces, outdoor environments, weather, crowds, and other ambient sounds generate appropriately for the scene. The ambient layer provides context and depth.
Describe environmental sounds in prompts for specific atmospheres. Veo 3.1 interprets scene descriptions and generates matching ambient audio.
4K Resolution and Upscaling
Veo 3.1 produces high-resolution output suitable for professional applications.
Native Resolution
Generate at 720p or 1080p with 24fps frame rate. The base resolution provides broadcast-quality output for most applications. Motion appears smooth and cinematic with natural camera work.
4K Upscaling
State-of-the-art upscaling extends output to 4K resolution. The upscaling process maintains quality and detail for large-screen viewing and high-fidelity production workflows. 4K output suits broadcast, cinema, and premium digital distribution.
Extended Video Duration
Create longer videos using Veo 3.1's Extend feature.
Initial Generation
Prompts generate 4, 6, or 8-second clips. These initial segments establish visual style, motion, and audio characteristics. The short duration ensures quality and coherence.
Extend Feature
The Extend feature continues videos seamlessly beyond initial generation. Build videos up to 148 seconds (over 2 minutes) by extending the action. Each extension maintains visual and audio continuity with the original.
Extended duration enables:
- Complete narrative sequences
- Full product demonstrations
- Tutorial content
- Promotional videos with full story arcs
Ingredients to Video
Multi-image control provides precise creative direction.
Character Control
Supply reference images for consistent character appearance. Characters maintain the same face, clothing, and features across scenes. Build narratives with recurring characters using visual references.
Object Control
Include specific items in generated content using reference images. Products, props, and visual elements appear as specified. Maintain brand consistency with controlled object placement.
Style Control
Apply visual style from reference imagery. Color palettes, lighting approaches, and artistic treatments transfer to generated content. Maintain visual consistency across project elements.
Frames to Video
Keyframe control for precise transitions.
Start and End States
Provide beginning and ending images for controlled generation. Veo 3.1 creates smooth video bridging the two frames. The transition maintains visual coherence throughout.
Creative Applications
- Artful scene transitions
- Object or character transformations
- Time-lapse style progressions
- Morphing effects between states
