Mocai vs Webcam Motion Capture

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.

Webcam Motion Capture uses a computer or smartphone camera to drive a 3D avatar, with tracking for hands and fingers, head and upper body, facial expressions, eye gaze, blinking, and lip sync. It can send tracking data to VMC-compatible apps, including VSeeFace and game engines using plugins, and can save motion data as FBX for use in Blender, Maya, and 3ds Max. The maker describes pairing it with OBS Studio to record or stream avatar video. It can also receive mocopi motion data and combine it with hand and face tracking. The FAQ lists Windows 10 or later and macOS Catalina or later; the listed platforms are iOS, macOS, and Windows. A free plan is available, but hiding the interface, sending tracking data to external apps, and saving FBX files require a subscription. The maker permits commercial content creation and monetization, while prohibiting resale or redistribution of the app.
