Frame
is divided into Key frames
and Transition frame

There may be no transition frame between two key frames (such as frame-by-frame animation), but there must be key frames before and after the transition frame, because the transition frame is attached to the key frame; the key frame can modify the content of the frame, but the transition frame cannot modify the frame content.
Key frames can contain various types of elements or elements such as shapes, clips, groups, etc., but objects in transition frames can only be clips (movie clips, graphic clips, buttons) or independent shapes.
