## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.


### Input Schema

The API accepts the following input parameters:


- **`prompt`** (`string`, _required_):
  Text prompt for video generation
  - Examples: "The camera slowly pulls back from the scene, revealing the full landscape as clouds drift overhead and light shifts across the terrain."

- **`duration`** (`integer`, _optional_):
  The duration of the video in seconds. Default value: `5`
  - Default: `5`
  - Range: `5` to `15`

- **`resolution`** (`ResolutionEnum`, _optional_):
  The resolution of the generated video. Default value: `"2K"`
  - Default: `"2K"`
  - Options: `"768P"`, `"2K"`, `"4K"`

- **`enable_prompt_expansion`** (`boolean`, _optional_):
  Whether to expand the prompt with a vision language model before generation. Default value: `true`
  - Default: `true`

- **`enable_safety_checker`** (`boolean`, _optional_):
  If set to true, the safety checker will be enabled. Default value: `true`
  - Default: `true`

- **`image_url`** (`string`, _required_):
  URL of the image to use as the first frame. The output aspect ratio follows this image.
  - Examples: "https://storage.googleapis.com/falserverless/example_inputs/hailuo23/pro_i2v_in.jpg"

- **`end_image_url`** (`string`, _optional_):
  Optional URL of the image to use as the last frame, for first-to-last keyframe generation.

- **`loras`** (`list<LoRAInput>`, _required_):
  List of LoRA adapters to apply to the transformer.
  - Array of LoRAInput



**Required Parameters Example**:

```json
{
  "prompt": "The camera slowly pulls back from the scene, revealing the full landscape as clouds drift overhead and light shifts across the terrain.",
  "image_url": "https://storage.googleapis.com/falserverless/example_inputs/hailuo23/pro_i2v_in.jpg",
  "loras": [
    {
      "path": "https://huggingface.co/owner/repo/resolve/main/lora.safetensors",
      "scale": 1
    }
  ]
}
```

```


### Output Schema

The API returns the following output format:

- **`video`** (`File`, _required_):
  The generated video



**Example Response**:

```json
{
  "video": {
    "url": "",
    "content_type": "image/png",
    "file_name": "z9RV14K95DvU.png",

}
```


## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/minimax/h3/image-to-video/lora \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "prompt": "The camera slowly pulls back from the scene, revealing the full landscape as clouds drift overhead and light shifts across the terrain.",
     "image_url": "https://storage.googleapis.com/falserverless/example_inputs/hailuo23/pro_i2v_in.jpg",
     "loras": [
       {
         "path": "https://huggingface.co/owner/repo/resolve/main/lora.safetensors",
         "scale": 1
       }
     ]
   }'
```

### 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(
    "minimax/h3/image-to-video/lora",
    arguments={
        "prompt": "The camera slowly pulls back from the scene, revealing the full landscape as clouds drift overhead and light shifts across the terrain.",
        "image_url": "https://storage.googleapis.com/falserverless/example_inputs/hailuo23/pro_i2v_in.jpg",
        "loras": [{
            "path": "https://huggingface.co/owner/repo/resolve/main/lora.safetensors",
            "scale": 1
        }]
    },
    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("minimax/h3/image-to-video/lora", {
  input: {
    prompt: "The camera slowly pulls back from the scene, revealing the full landscape as clouds drift overhead and light shifts across the terrain.",
    image_url: "https://storage.googleapis.com/falserverless/example_inputs/hailuo23/pro_i2v_in.jpg",
    loras: [{
      path: "https://huggingface.co/owner/repo/resolve/main/lora.safetensors",
      scale: 1
    }]
  },
  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);
```
