The gist

Motion2MixamoRig is an animation tool and Blender add-on that extracts body movement from standard video clips. It transfers that motion directly onto standard Adobe Mixamo 3D character models. It is designed for solo animators, indie game makers, and small creative studios looking to animate 3D characters without expensive motion-capture equipment.

What it does

Extracts full-body movement from a video clip of a single person
Converts single photo poses into matching 3D character stances
Applies captured movements onto Adobe Mixamo-rigged 3D characters
Exports ready-to-use 3D files in GLB format for Blender and Unity
Provides a one-click add-on interface inside Blender 4.2+

How it works

You provide a video of a person and a character model downloaded from Mixamo. The tool uses a 3D body model and vision AI to track joints and limb rotations across each video frame. It then retargets those movements onto the character's digital skeleton and saves an animated 3D model.

Best for

3D animators and game creators using Blender or Unity
Small creative teams needing quick character animation without mocap hardware
Solo artists animating humanoid characters using free Adobe Mixamo rigs

Watch out for

The video or photo must show only one person, visible from head to toe with no cropping
Requires downloading a separate SMPL-X body model file after registering on their site
Downloads about 5 GB of model weights during the first run
Currently experimental software tested primarily on Apple Silicon Macs
