Markers

No markers yet. Pick a body model above and MotionLab creates the markers, the skeleton links and the standard joint angles for you. Double-click a name to rename it.

Skeleton

No segments. A body model adds them automatically; “Join” connects any two markers by hand.

Data handling

✓

Video stays on this computer. The browser reads the file from disk and decodes it in memory.

✓

Analysis runs locally. Tracking, angles and kinematics are computed in this tab, not on a server.

✓

You control the outputs. Data leaves only when you export or save a project file.

✓

Projects and profile stay local. The library is stored in this browser on this computer. There is no account server and nothing is transmitted.
