## Use Cases

### Case 1: Quick Text-to-Video Generation

```json theme={null}
{
  "model": "MiniMax-Hailuo-02",
  "prompt": "A cute cat running on the grass in bright sunshine"
}
```

### Case 2: Generate High-Quality 1080p Video

```json theme={null}
{
  "model": "MiniMax-Hailuo-02",
  "prompt": "City night scene, neon lights flashing, traffic flowing",
  "duration": 5,
  "resolution": "1080p",
  "prompt_optimizer": true,
  "watermark": false
}
```

### Case 3: Generate Video from First Frame Image

```json theme={null}
{
  "model": "MiniMax-Hailuo-02",
  "prompt": "Person slowly turning around with a smile",
  "duration": 5,
  "resolution": "768p",
  "first_frame_image": "https://example.com/portrait.jpg"
}
```

### Case 4: Transition Video with First and Last Frame Control

```json theme={null}
{
  "model": "MiniMax-Hailuo-02",
  "prompt": "Scene gradually transitions from day to night, sky color changing",
  "duration": 10,
  "resolution": "768p",
  "first_frame_image": "https://example.com/day.jpg",
  "last_frame_image": "https://example.com/night.jpg",
  "prompt_optimizer": true
}
```

### Case 5: Fast Preprocessing Mode

```json theme={null}
{
  "model": "MiniMax-Hailuo-02",
  "prompt": "Waves crashing on the beach at sunset",
  "duration": 5,
  "resolution": "768p",
  "prompt_optimizer": true,
  "fast_pretreatment": true
}
```

<Note>
  **Query Task Results**

  Video generation is an asynchronous task that returns a `task_id` upon submission. Use the [Get Task Status](/en/api-reference/tasks/status) endpoint to query generation progress and results.
