## Balanced speed and quality

Veo 3.1 Fast sits in the middle of the Veo 3.1 family — faster than the flagship Veo 3.1 with more capability than Veo 3.1 Lite. Multi-reference image input (up to 3 images) and 4K resolution support are included.

Generation times are 60–90 seconds for 720p and 90–120 seconds for 1080p, making it practical for production workflows where quality and speed need to be balanced. The Transformer backbone with spatio-temporal patches is shared across the Veo 3.1 family.

## Prompting tips

* **Describe the visual scene in detail** — "A waterfall cascades in the background, mist rising into the air" sets a vivid visual scene.
* **Use reference images for product or character consistency** — Upload a product shot or character photo as a reference to anchor the visual in your generated clip.
* **Be specific about camera framing** — "Tight close-up," "wide establishing shot," or "over-the-shoulder angle" guide Veo 3.1 Fast's framing decisions.

### Example prompts

> A barista steams milk in an artisan coffee shop. Close-up on the steam wand, foam forming. Warm, cozy lighting. 8 seconds, 1080p.

> A coastal drone shot at sunrise. Wide angle, slow forward movement over calm ocean. Golden light, misty horizon. 8 seconds, 4K.

<Tip>
  Veo 3.1 Fast is the practical default choice in the Veo 3.1 family — it includes audio, supports 4K, and generates faster than the flagship. Move up to Veo 3.1 when you need the highest visual fidelity and full audio including dialogue and voiceover.
