# Visual Chronometer — Physical FPS Prediction
Safetensors conversion of the [Visual Chronometer](https://github.com/taco-group/Pulse-of-Motion) model for predicting the **Physical Frame Rate (PhyFPS)** from video motion patterns.
## Model Details
- **Architecture:** 2+1D VAE encoder + attention-pooled probe + MLP regression head
- **Training range:** 10–60 FPS
- **Output:** `log(FPS)` — take `exp()` to get predicted PhyFPS
- **Input:** 30-frame clips at 216×216 resolution, normalized to `[-1, 1]`
- **Parameters:** ~170M (683 MB safetensors)
## Format
This repo provides the model in **safetensors** format, converted from the original PyTorch Lightning checkpoint.

## Usage
Used by [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA) as the `phyfps` no-LLM mode for automated video temporal quality assessment.
