```

Configure your authentication:

```typescript theme={null}
import { fal } from "@fal-ai/client";

fal.config({
  credentials: "YOUR_FAL_API_KEY"
});
```

### Implementation Guide

Here's a basic example of generating a video from an image:

```typescript theme={null}
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("fal-ai/kling-video/v1.6/pro/image-to-video", {
  input: {
    prompt: "Snowflakes fall as a car moves along the road.",
    image_url: "https://storage.googleapis.com/falserverless/kling/kling_input.jpeg",
    duration: "5",
    aspect_ratio: "16:9",
    negative_prompt: "blur, distort, and low quality",
    cfg_scale: 0.5
  }
});

console.log(result.video.url);
```

### API Parameters

* `prompt` (required): Text description of the desired motion and scene
* `image_url` (required): URL of the input image
* `duration`: Video duration - "5" or "10" seconds
* `aspect_ratio`: Output aspect ratio (e.g., "16:9", "9:16", "1:1")
* `negative_prompt`: Elements to avoid in the generation
* `cfg_scale`: Classifier Free Guidance scale (default: 0.5)
* `static_mask_url`: URL for static motion brush mask
* `dynamic_mask_url`: URL for dynamic motion brush mask
* `special_fx`: Special effects like "hug", "kiss", "heart\_gesture", "squish", "expansion"

### Advanced Features

#### Motion Brush Control

```typescript theme={null}
const result = await fal.subscribe("fal-ai/kling-video/v1.6/pro/image-to-video", {
  input: {
    prompt: "Dynamic scene with controlled motion",
    image_url: "your-image-url",
    static_mask_url: "static-mask-url",
    dynamic_masks: [{
      mask_url: "dynamic-mask-url",
      trajectories: [
        { x: 279, y: 219 },
        { x: 417, y: 65 }
      ]
    }]
  }
});
```

#### Multi-Image Generation

For creating videos from multiple reference images (up to 4):

```typescript theme={null}
const result = await fal.subscribe("fal-ai/kling-video/v1.6/standard/elements", {
  input: {
    prompt: "A cute girl and a baby cow sleeping together",
    input_image_urls: [
      "first-image-url",
      "second-image-url"
    ]
  }
});
```

### Technical Specifications

Processing Capabilities:

* Input formats: JPG, JPEG, PNG, WebP, GIF, AVIF
* Output format: MP4
* Resolution: 1080p
* Duration options: 5 or 10 seconds
* Processing time: Approximately 6 minutes

### Best Practices

For optimal results:

Start with high-quality source images. The model performs best with clear, well-lit images that have distinct subjects and depth.

Consider your motion requirements. The cfg\_scale parameter controls prompt adherence - lower values (0.3-0.5) for more creative freedom, higher values for stricter prompt following.

Test different duration settings. 5-second clips often produce more focused results, while 10-second videos allow for more complex motion development.

### Model Variants

Kling offers two quality tiers:

* **Pro Mode**: Higher quality, longer processing time
* **Standard Mode**: Faster processing, good for quick iterations

Access standard mode at: `fal-ai/kling-video/v1.6/standard/image-to-video`

### Queue Management

For asynchronous processing:

```typescript theme={null}
// Submit request
const { request_id } = await fal.queue.submit("fal-ai/kling-video/v1.6/pro/image-to-video", {
  input: {
    prompt: "Your video description",
    image_url: "your-image-url"
  }
});

// Check status
const status = await fal.queue.status("fal-ai/kling-video/v1.6/pro/image-to-video", {
  requestId: request_id,
  logs: true
});

// Get result
const result = await fal.queue.result("fal-ai/kling-video/v1.6/pro/image-to-video", {
  requestId: request_id
});
```

### Pricing and Usage

* **Cost**: \$0.095 per video second
* 5-second video: \$0.475
* 10-second video: \$0.95
* Processing time: Approximately 6 minutes
