# InfiniteTalk - Talking Video Generator
Generate realistic talking head videos with accurate lip-sync from images or dub existing videos with new audio!
## Features
- **Image-to-Video**: Transform a static portrait image into a talking video using audio input
- **Video Dubbing**: Re-sync an existing video with new audio while maintaining natural head movements and expressions
- **High Quality**: 480p and 720p resolution support with advanced lip-sync technology
- **Unlimited Length**: Support for videos of any duration through chunked processing
## How It Works
InfiniteTalk uses the state-of-the-art Wan2.1 diffusion model combined with specialized audio conditioning to create photorealistic talking videos. The system synchronizes:
- Lip movements with audio
- Head pose and rotations
- Facial expressions
- Body posture
## Usage
### Image-to-Video
1. Upload a portrait image (clear face visibility recommended)
2. Upload an audio file or use the example
3. Adjust parameters if needed
4. Click Generate
### Video Dubbing
1. Upload a video with a visible face
2. Upload new audio to dub over it
3. Adjust parameters if needed
4. Click Generate
## Parameters
- **Resolution**: Choose between 480p (faster) or 720p (higher quality)
- **Diffusion Steps**: More steps = higher quality but slower (20-50 recommended)
- **Audio Guide Scale**: Controls audio influence on generation (2-4 recommended)
- **Seed**: For reproducible results
