[via: https://en.wikipedia.org/wiki/Motion_compensation ] Global motion compensation In global motion compensation, the motion model basically reflects camera motions such as: Dolly – moving the camera forward or backward Track – moving the camera left or right Boom – moving the camera up or down Pan – rotating the camera around its Y axis, moving the view left or right Tilt – rotating the camera around its X axis, moving the view up or down Roll – rotating the camera around the view axis
