Features
PixVerse V4.5 — Text-to-Video
PixVerse V4.5 Text-to-Video is a high-quality text-to-video generation model with support for resolutions up to Full HD 1080p. Generate detailed, cinematic videos from text descriptions with flexible aspect ratios and multiple resolution options.
Why It Stands Out
- Up to 1080p Full HD: Generate crisp, high-resolution videos for professional use.
- Multiple resolutions: Choose from 360p, 540p, 720p, or 1080p based on your needs.
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Flexible aspect ratios: Wide range from 16:9 widescreen to 9:16 vertical.
- Negative prompt support: Exclude unwanted elements for cleaner outputs.
- Reproducibility: Use the seed parameter to recreate exact results.
Parameters
| Parameter | Required | Description |
|---|---|---|

Pro Tips for Best Quality
- Be detailed in your prompt — describe subject, action, environment, lighting, and style.
- Include quality keywords like “4K,” “cinematic shot,” or specific visual descriptions.
- Use 360p or 540p for quick iterations, then generate final version at 1080p.
- Use negative prompts to reduce artifacts like blur or distortion.
- Match aspect ratio to your target platform before generating.
Notes
- Processing time varies based on resolution, duration, and current queue load.
- For faster generation at lower cost, consider PixVerse V4.5 Fast.
- Please ensure your prompts comply with content guidelines.
