# xai/video (xAI Grok Video Generation)
|
|
|
|
You can run this example with:
|
|
|
|
```bash
|
|
npx promptfoo@latest init --example xai/video
|
|
cd xai/video
|
|
```
|
|
|
|
This example demonstrates video generation using xAI's Grok Imagine API.
|
|
|
|
## Setup
|
|
|
|
1. Set your xAI API key:
|
|
|
|
```bash
|
|
export XAI_API_KEY=your_api_key_here
|
|
```
|
|
|
|
2. Run the evaluation:
|
|
|
|
```bash
|
|
npx promptfoo@latest eval
|
|
```
|
|
|
|
## Configuration Options
|
|
|
|
| Option | Type | Default | Description |
|
|
| -------------- | ------ | ------- | -------------------------------------------------- |
|
|
| `duration` | number | 8 | Video length in seconds (1-15) |
|
|
| `aspect_ratio` | string | 16:9 | Aspect ratio (16:9, 4:3, 1:1, 9:16, 3:4, 3:2, 2:3) |
|
|
| `resolution` | string | 720p | Output resolution (720p, 480p) |
|
|
|
|
## Advanced Features
|
|
|
|
### Image-to-Video
|
|
|
|
Animate a static image:
|
|
|
|
```yaml
|
|
providers:
|
|
- id: xai:video:grok-imagine-video
|
|
config:
|
|
image:
|
|
url: 'https://example.com/image.jpg'
|
|
```
|
|
|
|
### Video Editing
|
|
|
|
Edit an existing video:
|
|
|
|
```yaml
|
|
providers:
|
|
- id: xai:video:grok-imagine-video
|
|
config:
|
|
video:
|
|
url: 'https://example.com/video.mp4'
|
|
|
|
prompts:
|
|
- 'Make the colors more vibrant'
|
|
```
|
|
|
|
### Reference-to-Video
|
|
|
|
Guide the generated video with up to seven reference images:
|
|
|
|
```yaml
|
|
providers:
|
|
- id: xai:video:grok-imagine-video
|
|
config:
|
|
reference_images:
|
|
- url: 'https://example.com/person.jpg'
|
|
- url: 'https://example.com/shirt.jpg'
|
|
duration: 10
|
|
```
|
|
|
|
`reference_images` cannot be combined with `image` or `video`, and reference-guided videos are limited to 10 seconds.
