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.
Mocai
Mocai reconstructs a subject’s body, mesh, and motion from one video as markerless motion capture. The maker says footage from any single camera, including a phone, works without markers, suits, or calibration. Each performer has 70 tracked keypoints, and skeleton exports use a 127-joint rig. Capture options include finger articulation, multiple performers, root motion, floor grounding, occlusion repair, adjustable smoothing, and synchronized footage review. Exports include FBX, GLB, BVH, USD, and raw keypoints, with optional retargeting to Mixamo, UE5 Manny, and MetaHuman rigs. Plugins for Blender, Unity, Maya, and Unreal Engine support clip uploads and take imports. A public API supports uploads and webhooks; an MCP server can manage takes and exports. The free plan includes one minute of footage per month, clips up to 15 seconds, and single-person capture. Basic costs $10 a month for 10 minutes monthly and clips up to 30 seconds. The monthly footage allowance is shared between portal and API use, and uploads pause when it is reached.
