ShengShu’s Vidu Q3 Turbo: fast clips with sound at 540p to 1080p, 1 to 16 seconds, from a prompt, a start image, or a start and an end image.

## Prices

| Model | Resolution | Per second | 5 second clip |
| --- | --- | --- | --- |
| [Vidu Q3 Turbo](https://zurelay.com/models/vidu-q3-turbo) | 540p | $0.03 | $0.15 |

A clip costs its length times the rate: a 5 second 540p clip is $0.15. It’s charged only when the video is delivered.

## What it takes

- A prompt of up to 2,000 characters.
- A `first_frame` to animate, and optionally a `last_frame` to land on. No reference images.
- Lengths from 1 to 16 seconds, in whole seconds.
- 16:9, 9:16, 1:1, 4:3 and 3:4. From a first frame, the video takes the image’s shape.
- Sound comes at no extra cost; set `generate_audio` to `false` for a silent clip.
- 540p, 720p and 1080p.

## Example

Request body:

```json
{
  "model": "vidu-q3-turbo",
  "first_frame": "https://example.com/storefront-day.jpg",
  "last_frame": "https://example.com/storefront-night.jpg",
  "prompt": "Time passes from afternoon to night; the lights come on inside the shop.",
  "seconds": 5,
  "resolution": "720p"
}
```

## Prompting

- Describe the motion and the camera, not just the scene.
- For a start and end image, describe what changes between them.
- A `seed` makes a result you liked again with small changes.

## Good to know

- Short clips usually take about a minute.
- Images you send are kept for up to two days so the model can read them, then deleted.
- 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.
