    arguments={
        "prompt": "A woman walking through a vibrant city street at night, neon lights reflecting off wet pavement.",

    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("fal-ai/vidu/q2/image-to-video/pro", {
  input: {
    prompt: "A woman walking through a vibrant city street at night, neon lights reflecting off wet pavement.",
    image_url: "https://storage.googleapis.com/falserverless/web-examples/vidu/stylish_woman.webp"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
