@ ninhalo5,

If you are interested in tracking the camera, you may want to try my "Tracker Cam" available in the free stuff. It's not a python script, but a camera parented to props, it uses ERC to track the x and z movement of the figure, without any bounce, pitch  or roll. Its an orbital style camera, not a dolly, it only works on figures. By default it tracks both the body and hip, but is configurable in respect to what it tracks and how.
