# AI Video Generation

### Image to Video

Image to video converts an image into a 5-second video. Provide a URL to an image to generate an mp4 video file. The video
file can be used inside of your Edit or as a standalone asset. We accept PNG, JPG and PNG images.

```json
{
    "asset": {
        "type": "image-to-video",
        "src": "https://shotstack-assets.s3.amazonaws.com/images/handbag-flower-peaches.jpg",
        "prompt": "Slowly zoom out and orbit left around the object."
    },
    "start": 0,
    "length": "auto"
}
```

This will generate a video clip of the supplied image.

The generated video will automatically be cropped to fit the output dimensions of your video. You can change the `fit` property of the clip to change this behaviour.

:::info Info

Videos will always be 720p, 25fps and 6 seconds in length.
