Why Free Browser Motion Capture (Mocap Alternative) Works Here
Marker-free skeleton tracking
MoveNet-based pose estimation tracks body joints directly from video, no reflective markers or suit required.
Export tracked coordinates
Motion Tracking Data Export writes per-frame joint positions and speed to CSV.
Two model tiers
Lightning (fast) or Thunder (more precise) depending on how much accuracy your use case needs.
Multi-person capture
Track more than one person's skeleton in the same shot, each with a stable ID.
Works from any camera or clip
Live webcam or an uploaded video file — same tracking pipeline either way.
Free, no studio required
Runs entirely in a browser tab — no dedicated mocap volume or hardware needed to get started.
Frequently Asked Questions
Is this as accurate as a real mocap rig?
No — it's a free, camera-based 2D pose estimate, not a marker-based volumetric capture system. It's a starting point, not a studio replacement.
Can I export the joint data?
Yes — Motion Tracking Data Export writes tracked coordinates and speed to a CSV file.
Does it track in 3D?
Tracking is 2D (screen-space) from a single camera, not full 3D depth.
Can I use a recorded video instead of a live camera?
Yes — upload a video file and it's tracked the same way.
Is it free?
Yes — no signup, no watermark, nothing to install.
