Key Features

Monocular video input
3D body motion reconstruction
Flow-matching model
Physics-based GRPO post-training
Browser motion preview
NPZ output
Optional FBX export
Released inference and training tools

The motion model combines flow matching with physics-based post-training. Its inference workflow extracts body and camera information and reconstructs a motion sequence that can be inspected through the browser demo or the command-line tools.


Animators and robotics researchers can use the output as a first pass for retargeting and simulation. The project includes sample motions, checkpoint setup guidance and optional FBX export for bringing reconstructed motion into a compatible pipeline.
