iPi Mocap Studio vs XR Animator

iPi Mocap Studio analyzes recordings made with iPi Recorder to track an actor’s movement and produce skeleton animation for humanlike characters. It accepts multi-camera or depth-sensor video and includes motion cleanup, refinement, jitter removal, trajectory filtering, and manual finger-pose keyframing. Character import and animation export support FBX, BVH, Collada, DMX, and SMD. Basic and Pro editions can stream poses to Unity projects through supplied C# scripts. Pro adds multi-person tracking, multiple-GPU support, and batch processing. The 30-day trial includes Basic features, but animation export and live preview stop being available afterward. AI tracking requires 64-bit Windows 10 or 11 and a compatible NVIDIA RTX or Quadro RTX GPU; documented AI features cover single-actor color-video projects. Licenses use online activation, one computer at a time, and an offline option is documented. The software runs on Windows 7, 8, 8.1, 10, and 11. The listed Biomech Add-on costs $245 a month.

XR Animator is a free tool for driving MMD or VRM 3D avatars from pose input. It uses MediaPipe and TensorFlow.js to detect poses from webcam video, and supports face, full-body, and combined face, body, and hand tracking. Full-body tracking can use a webcam or an image or video file. Face tracking supports 52 ARKit-compatible blendshapes. Users can record motion capture, export VMD, BVH, and glTF motion, and load VMD, FBX, and BVH motion files; FBX or BVH motion can also be exported to VMD. The scene can include 2D images or video, 3D panoramas, and .x or .glb objects. The web app works in major desktop and smartphone browsers, while Electron apps are available for Windows, Linux, and macOS. Android Chrome supports augmented reality. VMC protocol support and a frameless transparent background for capture apps are limited to Electron mode. The project notes that smartphones with limited processing power may be better suited to face tracking alone.
