ComfyUI nodes for Pulse-of-Motion - a Visual Chronometer that predicts Physical FPS (PhyFPS) from video frames.

Installation

cd ComfyUI/custom_nodes
git clone https://github.com/DiXiaoO/ComfyUI-Pulse-of-Motion.git
pip install -r ComfyUI-PulseOfMotion/requirements.txt

Model Weights

Download vc_common_10_60fps.ckpt from HuggingFace and place it in:

ComfyUI/models/visual_chronometer/

Usage

1. Add Pulse-of-Motion Model Loader node - select model and device
2. Add PhyFPS Detector node - connect model and video frames
3. Run - get Physical FPS prediction

Parameters

PhyFPS Detector

• stride: Sliding window step (default: 4). Lower values = more segments = slower but more accurate.

Output

• phyfps: Predicted Physical FPS (float)
• info: Detailed segment predictions
