This endpoint doesn't generate the video instantly, you can use the Fetch endpoint to fetch the result or use webhooks.

The result (posted to the webhook_url or retrieved with the Fetch endpoint) looks like this:

{
    "task_id": "29e983ca-7e86-4017-a9e3-ef6fe9cd5f2a",
    "task_type": "luma-ext",
    "video_url": "https://...........xxxx.mp4", // 
}

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

{
    "task_id": "29e983ca-7e86-4017-a9e3-ef6fe9cd5f2a",
    "task_type": "luma-ext",
    "status": "processing",
    "percentage": "40",
}
