In fullsize pose capture, root should be at feet

[j2l]

In pose capture, when I balance arms left and right, the whole body is seen as rotating around Y axis. Even after zeroing hip center rotation, hip left and right Z locations, feet rotate around Y axis. Here I had my 2 feet on the ground, only my hands are on the left: selected are 3 hips curves (center Y rotation, Z locations for the 2 others) and you can see they are zero. I don't know mediapipe and in the capture, I was not rotating on screen.

Is there a way to set root to feet for us non-dancers? 😄
