## Pricing

* **Pricing Type**: Video length based pricing
* **Price**: \$0.056 per second
* **Unit**: Second

Example cost calculation:

* 5-second video: 5 × $0.056 = $0.28
* 10-second video: 10 × $0.056 = $0.56

## Video Specifications

* **Duration**: 5-10 seconds
* **Aspect Ratios**:
  * Landscape: 16:9 (default)
  * Portrait: 9:16
  * Square: 1:1
* **Quality**: Up to 720p resolution with smooth motion
* **Format**: MP4 video with thumbnail image

## Tips for Better Results

1. **Clear, Descriptive Prompts**: Use specific, detailed descriptions for better video quality
2. **Motion Description**: Include details about camera movement and scene dynamics
3. **Negative Prompts**: Use negative prompts to avoid unwanted elements like blur or distortion
4. **CFG Scale Tuning**:
   * Lower values (0.3-0.5): More creative, less prompt adherence
   * Higher values (0.7-1.0): More prompt adherence, less creative variation
5. **Aspect Ratio Selection**: Choose based on intended use (16:9 for landscape, 9:16 for mobile, 1:1 for social media)
6. **Duration Planning**: Use 5 seconds for quick concepts, 10 seconds for more complex scenes
