| Export formats | Results include CSV, FBX, and .blend files, among other formats. | Exports include FBX, GLB, BVH, USD, and raw keypoints, with optional retargets to Mixamo, UE5 Manny, and MetaHuman rigs. |
| Privacy | Video processing is local; optional anonymous usage pings can send an IP address, timestamp and camera information, and users can disable those pings. | Mocai says customers own their footage and reconstructions, uploads are not used to train machine-learning models, and stored takes are automatically deleted after the plan’s retention period. |
| Support | Community support is centered on Discord, with GitHub issues for bugs and feature requests and paid setup, training and custom services available. | The maker invites customers to contact it and says Enterprise plans can include custom builds, integrations, and usage limits. |
| What it does | FreeMoCap records synchronized camera video and reconstructs full-body 3D movement without physical markers. | Mocai reconstructs a subject’s body, mesh, and 127-joint skeleton from a single video as markerless motion capture. |

In their own words
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.
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.
