See what you made
Right after a recording finishes, two questions matter: did it actually track your movement, and where did everything go.
The fastest check: did Blender open
If Blender was detected on your system, FreeMoCap opens a scene automatically when processing finishes: a skeleton moving through the motion you just recorded. Look for the obvious stuff first, does it move the way you moved, are all your limbs where they should be, is anything flying off into space or frozen in place. That's enough to tell you whether the whole pipeline worked, before you look at any actual data.
If Blender wasn't detected, or didn't open automatically, see open your recording in Blender.
If you want to check without Blender
Every recording also gets an annotated video: your original footage
with the detected keypoints drawn directly on top. It's in the
recording's annotated_videos/ folder (see
find and read your output for the full
layout), and it's the fastest way to sanity-check 2D tracking by eye
without needing Blender at all.
What "worked" looks like, and what didn't
Good signs: keypoints in the annotated video sit on the actual joints and move smoothly frame to frame. In Blender, the skeleton's proportions look roughly human and its motion matches what you did.
Signs something's off:
- Keypoints jumping around or disappearing in the annotated video usually means a lighting or contrast problem, not a software bug. See optimize your capture space.
- A skeleton that's lying down, mirrored, or wildly out of scale in Blender (multi-camera recordings only) usually points to the calibration, not the recording itself. See get a calibration you can trust.
A single-camera recording won't give you reliable 3D positions no matter how clean the tracking looks, that's expected, see cameras and synchronization for why. If 2D tracking looked clean and you're ready for real 3D data, that's the cue to move on to multiple cameras.
