Camera Animation Issues

GeneralDee

I been animating cameras around figures with no problem the past couple days. But all of a sudden now when I create a camera and do a simple zoom in, the camera starts rotating with the character going off screen and a rotating shot is causing the camera to do back flips. I think I may have clicked something by mistake or something just went wrong because I didn't have this problem before tonight. I even successfully did a few camera animations earlier with the same scene. Does anyone know why the camera would behave like this?
