Chapter 3. Animate Your Art
In the olden days of animation, artists had to create a drawing for each frame of a movie by hand.

To keep costs down, animation production companies had their best, highest-paid artists draw the most important images, where major changes took place, and then had lesser talents and beginners draw the in-between images. Those most important images are known as keyframes. The in-betweeners are called tweens.
This chapter is your introduction to keyframes and tweens from Flash’s point of view. In this case, you’re the high-paid artist who gets to create the keyframes, while your computer does the grunt work of drawing all the tweens. You’ll learn about two types of tweens—the motion tween and the shape tween. But first, you need to understand the various types of frames you see in Flash’s timeline.
