Using pan-and-scan
Another way to use keyframe animation in the Event Pan/Crop window is panning, or pan-and-scan. Pan-
and-scan is a technique commonly used when film is converted for television. Movie screens and film are
usually wider (~2.35:1) than television (~1.33:1). When you transfer the film to video, you have four
choices: (1) squash the film horizontally to fit, distorting it in the process; (2) crop it, possibly losing
information on the sides; (3) letter box it so the top and bottom have black areas and the picture is shorter
overall; and (4) pan-and-scan. Pan-and-scan is a variation of cropping, where someone goes through the
movie and moves the crop area back and forth to follow the action or subject.
