ComfyUI LiteTracker

ComfyUI custom nodes for LiteTracker, a fast and efficient point tracking model for videos.

This implementation wraps the original ImFusionGmbH/lite-tracker repository as ComfyUI nodes.

Features

• Load Model node: Download and load LiteTracker weights
• Track node: Track points across video frames with online processing
• Grid Editor node: Graphical interface to define multiple rotatable tracking regions with custom point density

Installation

1. Clone this repository into your ComfyUI custom nodes directory:

cd ComfyUI/custom_nodes/
git clone https://github.com/fuselayer/comfyui-lite-tracker.git
pip install -r requirements.txt

2. Restart ComfyUI

Usage

Drag and drop this image into ComfyUI and move the video and mask files to ComfyUI/input:
