This endpoint doesn't generate videos instantly; you can use the [Fetch](https://docs.apiframe.ai/api-endpoints/fetch) endpoint to fetch the result or use [webhooks](https://docs.apiframe.ai/webhooks).

The result (posted to the `webhook_url` or retrieved with the [Fetch](https://docs.apiframe.ai/api-endpoints/fetch) endpoint) looks like this:

```json
{
    "task_id": "29e983ca-7e86-4017-a9e3-ef6fe9cd5f2a",
    "task_type": "imagine-video-extend",
    "video_urls": [
        "https://.../xxxx1.mp4",
        "https://.../xxxx2.mp4",
        "https://.../xxxx3.mp4",
        "https://.../xxxx4.mp4"
    ]
}
```

If the job is not completed, you will get a result like this:

```json
{
    "task_id": "29e983ca-7e86-4017-a9e3-ef6fe9cd5f2a",
    "task_type": "imagine-video-extend",
