I watched this video https://youtu.be/xlxDXjauszg to try and get the linear kinematics of a vertical jump. For some reason I didn't get the same data he did. I'm thinking maybe it's because my marker went out of the view of the camera? Or maybe there's something else I did wrong? I'm attaching the link of a screen recording I did and then you guys can tell me what I did wrong because I want to get linear kinematics correct.

Also what is the correct distance that the camera should be when recording myself? Did that mess up the data as well?

Thank you. Below is the link for my video process

Replying to my own issue. The problem was that I was calibrating the measurement upside down. I was drawing a line from the hip to the knee when it should have been from the knee to the hip. Once I corrected that, my issue went away.
