In their own words
Autodesk MotionBuilder
Autodesk MotionBuilder is 3D character animation software for capturing, editing, and playing back complex animations. Its real-time character engine automatically creates movements for biped or human skeletons, while manipulation tools let users alter a character’s position and orientation. The listed capabilities include motion capture, motion retargeting, facial animation, animation retargeting, and character retargeting. Autodesk says professional animation and game studios use MotionBuilder to produce animations. It is designed to complement Maya and 3ds Max and exchanges data through Autodesk FBX with applications that support FBX. MotionBuilder is available for Linux and Windows. The stated minimum hardware includes a 64-bit Intel or AMD multi-core processor, 8 GB RAM, 4 GB of free disk space, and a three-button mouse. Autodesk offers a free 30-day trial, but no free plan. A subscription covers installation on up to three devices for one named user, with use limited to one computer at a time, and includes the current version plus three previous versions.
FreeMoCap
FreeMoCap records and reconstructs full-body movement as 3D motion-capture data. It is free, open-source software for researchers, animators, athletes, and creators. Capture can use two or more standard webcams, GoPros, or smartphones; a printed ChArUco board synchronizes camera feeds and defines the 3D coordinate system. Users can also record video offline on mobile devices and import it later for processing. Results can be exported in formats including CSV, FBX, and .blend files. A Blender add-on loads processed recordings into Blender as a rigged skeleton. Processing happens locally, and the homepage says video data does not leave the user's machine. A backend server download supports headless machines, remote capture rigs, and API use. The download page identifies the current release as alpha. Optional anonymous usage pings may include IP address, timestamp, and camera information, but users can disable them in the GUI. The project directs questions to Discord and bug reports or feature requests to GitHub. Its post-hoc guide notes that RTMPose produces 3D data but does not currently have working Blender export.
