joint3d's z coordinate change largely

[qinb]

Hi, Thank you for sharing such excellent research. I try to infer my own video and obtain model_joints after the run-fitting phase, unfortunately, it's strange that model joints' z coordinate change largely when the video's motion move in the x, y direction not z.

Please tell me how to resolve this problem, Thanks! @nkolot @geopavlakos

I also smooth the predicted pose, but the predicted joint3d'z coordinate still jumps back and forth. why happen this phenomenon? looking forward to your response, thanks. @nkolot @geopavlakos
