This endpoint doesn't generate the video instantly, you can use the [Fetch](/api-endpoints/fetch.md) endpoint to fetch the result or use [webhooks](/webhooks.md).

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

```json
{
    "task_id": "29e983ca-7e86-4017-a9e3-ef6fe9cd5f2a",
    "task_type": "seedance-video",
    "video_url": "https://...........xxxx.mp4", // 
    "status": "finished",
    "percentage": 100
}
```

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

```json
{
    "task_id": "29e983ca-7e86-4017-a9e3-ef6fe9cd5f2a",
    "task_type": "seedancee-video",
    "status": "processing",
    "percentage": "40",
}
```

Credit cost:

With `generate_audio: true`, all costs are doubled.
