Blender Motion Capture

Overview

Import, process, and retarget motion capture data in Blender using Python. Work with BVH/FBX mocap files, track camera and object motion from video footage, solve 3D camera paths, and clean up animation data. Checked against the Blender 5.2 Python API reference.

Blender 5.0 changed how animation data is stored: an Action now has layers, strips and slots, and F-Curves live in a channelbag (action.layers[0].strips[0].channelbag(slot).fcurves), not in action.fcurves. Code written for 4.x that touches action.fcurves fails on 5.x.

Instructions

1. Import BVH motion capture files
