### Python

Ensure you have the Python client installed:

```bash
pip install fal-client
```

Then use the API client to make requests:

```python
import fal_client

def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "xai/grok-imagine-video/edit-video",
    arguments={
        "prompt": "Colorize the video",
        "video_url": "https://v3b.fal.media/files/b/0a8b9112/V5Z_NIPE3ppMDWivNo6_q_video_019.mp4"
    },
    with_logs=True,
    on_queue_update=on_queue_update,
)
print(result)
```

### JavaScript

Ensure you have the JavaScript client installed:

```bash
npm install --save @fal-ai/client
```

Then use the API client to make requests:

```javascript
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("xai/grok-imagine-video/edit-video", {
  input: {
    prompt: "Colorize the video",
    video_url: "https://v3b.fal.media/files/b/0a8b9112/V5Z_NIPE3ppMDWivNo6_q_video_019.mp4"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);
```
