Play it Again
You can
see a preview of your stars by clicking the Play button at
the bottom of the task bar.
As the
play progresses, watch
the timing sequence in the Animation task bar. This is a
mini-version of the tools available to video editors.
Try
it: Play the Animation
What did you see? How long did it take to animate your
sequence? Does it seem longer when there is nothing animated on
the screen?
