+# MeiGen-MultiTalk Demo
+
+This is a demo of MeiGen-MultiTalk, an audio-driven multi-person conversational video generation model.
+
+## Features
+
+- 💬 Generate videos of people talking from still images and audio
+- 👥 Support for both single-person and multi-person conversations
+- 🎯 High-quality lip synchronization
+- 📺 Support for 480p and 720p resolution
+- ⏱️ Generate videos up to 15 seconds long
+
+## How to Use
+
+1. Upload a reference image (photo of person(s) who will be speaking)
+2. Upload an audio file
+3. Enter a prompt describing the desired video
+4. Click "Generate Video" to process
+
+## Tips
+
+- Use clear, front-facing photos for best results
+- Ensure good audio quality without background noise
+- Keep prompts clear and specific
+- Supported formats: PNG, JPG, JPEG for images; MP3, WAV, OGG for audio
+
+## Limitations
+
+- Generation can take several minutes
+- Maximum video duration is 15 seconds
+- Best results with clear, well-lit reference images
+- Audio should be clear and without background noise
+
+## Credits
+
+This demo uses the MeiGen-MultiTalk model created by MeiGen-AI.

+# MeiGen-MultiTalk Demo
+
+This is a demo of [MeiGen-MultiTalk](https://huggingface.co/MeiGen-AI/MeiGen-MultiTalk), an audio-driven multi-person conversational video generation model.
+
+## Features
+
+- 💬 Generate videos of people talking from still images and audio
+- 👥 Support for both single-person and multi-person conversations
+- 🎯 High-quality lip synchronization
+- 📺 Support for 480p and 720p resolution
+- ⏱️ Generate videos up to 15 seconds long
+
+## How to Use
+
+1. Upload a reference image (photo of person(s) who will be speaking)
+2. Upload one or more audio files:
+   - For single person: Upload one audio file
+   - For conversation: Upload multiple audio files (one per person)
+3. Enter a prompt describing the desired video
+4. Adjust generation parameters if needed:
+   - Resolution: Video quality (480p or 720p)
+   - Audio CFG: Controls strength of audio influence
+   - Guidance Scale: Controls adherence to prompt
+   - Random Seed: For reproducible results
+   - Max Duration: Video length in seconds
+5. Click "Generate Video" and wait for the result
+
+## Tips
+
+- Use clear, front-facing photos for best results
+- Ensure good audio quality without background noise
+- Keep prompts clear and specific
+- For multi-person videos, ensure the reference image shows all speakers clearly
+
+## Limitations
+
+- Generation can take several minutes
+- Maximum video duration is 15 seconds
+- Best results with clear, well-lit reference images
+- Audio should be clear and without background noise
