Google’s Veo 3.1 Fast: 8 second 720p clips with dialogue, sound effects and ambient sound, from a prompt or a start image.

## Prices

| Model | Resolution | Per second | 8 second clip |
| --- | --- | --- | --- |
| [Veo 3.1 Fast](https://zurelay.com/models/veo-3.1-fast) | 720p | $0.025 | $0.20 |

A clip costs its length times the rate: a 8 second 720p clip is $0.20. It’s charged only when the video is delivered.

## What it takes

- A prompt of up to 8,000 characters.
- A `first_frame` to animate. No reference images.
- Lengths from 8 to 8 seconds, in whole seconds.
- 16:9 and 9:16. From a first frame, leave out `aspect_ratio` and the clip takes the image’s shape: 9:16 for a portrait image, 16:9 otherwise.
- Sound is always on.
- 720p.

## Example

Request body:

```json
{
  "model": "veo-3.1-fast",
  "first_frame": "https://example.com/presenter.jpg",
  "prompt": "She holds up the serum bottle, smiles and says: \"Two weeks with this serum and my skin is glowing.\" Handheld phone video, soft window light."
}
```

## Prompting

- Describe the shot, the motion and the camera, then the sound: who says what, in quotes, and the effects.
- From a start image, describe what happens next: the motion, the camera and the sound.
- Google supports English prompts best.

## Good to know

- Clips usually take one to two minutes.
- Every clip is 8 seconds at 720p, so you can leave out `seconds` and `resolution`.
- There’s no end frame (clips made with one carry a visible Veo mark), negative prompt or seed. Clips carry Google’s invisible SynthID watermark, and no visible one.
- Prompts or images that may break the content rules can be declined (`content_policy`); declined videos are free.
- Videos are kept for 30 days; download the ones you want to keep.
