Follow these steps to set up and use InfiniteTalk for creating unlimited-length talking videos with accurate lip synchronization and natural body motion
Install the required dependencies including PyTorch, xformers, flash-attn, and other supporting libraries. Create a conda environment with Python 3.10 and install the necessary packages for optimal performance.
Download the required model files including the base Wan2.1-I2V-14B-480P model, chinese-wav2vec2-base audio encoder, and InfiniteTalk weights from the official Hugging Face repositories.
Prepare your input materials - either a single image for image-to-video generation or an existing video for video-to-video dubbing. Ensure your audio file is properly formatted and synchronized.
Configure the generation parameters including resolution (480P or 720P), sampling steps, motion frames, and other settings based on your hardware capabilities and quality requirements.
Run the generation process using the appropriate command-line interface or ComfyUI integration. Monitor the progress as the system processes your content in chunks with overlapping frames.
Apply any necessary post-processing steps such as frame interpolation to double the FPS, color correction, or other enhancements to achieve the desired final quality.
