- Multiple resolutions: Choose from 360p, 540p, or 720p based on your needs.
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Flexible aspect ratios: Support for various aspect ratio presets.
- Negative prompt support: Exclude unwanted elements for cleaner outputs.
- Reproducibility: Use the seed parameter to recreate exact results.

- Use 360p or 540p for quick iterations, then generate final version at 720p.
- Include motion keywords like "slow motion," "dynamic," or "cinematic."
- Use negative prompts to reduce artifacts like blur or distortion.
- Match aspect ratio to your target platform before generating.
