Veo 3.1 Fast
Google's high-fidelity video generation model with native audio, cinematic control, and image-to-video capabilities — now optimized for speed.
Overview
What is Veo 3.1 Fast
Veo 3.1 Fast is Google's optimized video generation model, released in October 2025 as a faster variant of Veo 3.1. It supports both text-to-video and image-to-video generation, produces up to 8-second clips in 4K with native audio, and delivers cinematic quality with improved prompt adherence and motion consistency.
Running it privately on Venice
On Venice, Veo 3.1 Fast runs under an anonymized privacy tier — your prompts are not stored or profiled. This means you can generate high-resolution, audio-rich video content without leaving a trace, ideal for creators prioritizing sovereignty and discretion. The model is uncensored and runs permissionlessly, enabling unrestricted creative exploration.
Assessment
Strengths and limitations
- Native audio generation synchronized with video, supporting ambient sounds, dialogue, and music.
- Strong prompt adherence and cinematic realism, with improved understanding of complex camera movements and styles.
- Dual-mode support: generates video from text or animates still images with motion.
- Maintains character and scene consistency when using reference images or extending videos.
- Available in high-resolution 4K output with photorealistic detail and cinematic framing.
- Closed and proprietary: no open weights, so self-hosting or fine-tuning is not possible.
- Limited to 8-second clips, which may not suit longer-form storytelling needs.
- No support for object insertion, removal, or video editing within the model itself.
- Available only in select regions (e.g., us-central1), limiting global access.
Samples
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera

Variants
Veo 3.1 Fast model variants
Veo 3.1 Fast runs on Venice as 2 variants of the same underlying model. Pick by what you're starting from: a written prompt, a still image, reference images, or an existing clip. Each variant is its own model id on the API; the generation quality is the same across the family.
| Variant | What it is | Clip lengths | Resolutions | Aspect ratios | Audio | Model ID |
|---|---|---|---|---|---|---|
| Text to Videoflagship | Generate a clip from a written prompt | 4s, 6s, 8s | 720p, 1080p, 4k | 16:9, 9:16 | veo3.1-fast-text-to-video | |
| Image to Video | Animate a still image into motion | 4s, 6s, 8s | 720p, 1080p, 4k | — | veo3.1-fast-image-to-video |
Capability data comes straight from the Venice model API and refreshes with every catalog ingest. The specs and pricing on this page are captured from the flagship variant; pass the model id of the variant you want to the API.

Prompting
Getting better results
Use descriptive cinematic language — mention camera movements, lighting, and mood for best results.
For image-to-video, start with high-quality, high-resolution stills for smoother animation.
Include audio cues in your prompt (e.g., 'mellow hip-hop beat', 'city murmurs') to guide sound generation.
Use reference images to maintain character or object consistency across generations.
Keep prompts focused — longer prompts don't improve quality and may reduce coherence.
