ComfyUI Sync Lipsync Node

This custom node allows you to perform audio-video lip synchronization inside ComfyUI using a simple interface.

Installation & Usage

After cloning ComfyUI and setting up a virtual environment for it, follow these steps:

1. Navigate to the custom nodes directory:
   cd /path/to/ComfyUI/custom_nodes/

2. Clone this repository:
   https://github.com/synchronicity-labs/sync-comfyui.git

3. Install the required dependencies:
   pip install -r requirements.txt

IMPORTANT: If you want to ignore steps 2-3, just run comfy node install comfyui-sync-lipsync-node in your /path/to/ComfyUI/custom_nodes/

5. Go back to the main ComfyUI directory and run:
   cd /path/to/ComfyUI/
python main.py

6. A link will be printed in the terminal — open it in your browser to access the ComfyUI GUI.

7. In the ComfyUI interface:

   • On the left sidebar, go to the Nodes tab.
   • Search for Sync. You will find three sync nodes; one for input, one for generation and one for output. Connect them to each other.
   • Input your video, audio, and API key. For audio and video, you can give a url or a local path as an input. The local files should be in the ComfyUI repository that you are using.
   • Click Run to generate the synced output.
   • It will save the video along with the job_id in a json file.
