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
- 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
Restart ComfyUI The model weights will be automatically downloaded on first use.
Usage
Drag and drop this image into ComfyUI and move the video and mask files to ComfyUI/input
