Using Flash, you can animate objects to make them appear to move across the Stage and/or change their shape, size, colour, opacity, rotation, and other properties. You can create frame-by-frame animation, in which you create a separate image for each frame. You can also create tweened animation, in which you create the first and last frames of an animation and direct Flash to create the frames in between.

A keyframe is a frame in which you define a change in an animation or include frame actions to modify a movie. Flash can tween, or fill in, the frames between keyframes to produce fluid animations. Because keyframes let you produce animation without drawing each frame, they make creating movies easier.
