Repeat the last step to extend the animation, but only on your first fireworks layer; copy frame 1 to frame 24, and then copy it again to frames 12 and 13, so that you have a total of four key frames and two static spaces in between. Notice that you won’t be able to see the contents of the frames, save for as a small blue and white dot on the screen; this is because, as I said before, the movie clip doesn’t play over successive frames in the main scene, and so until your final preview/export you won’t see the expanding and shrinking fireworks burst; only the first frame of it, which we’ve made rather small.
Flash Animation 4: Animating Your E-card
By Adrien-Luc Sanders, About.com
Now we’re going to use a Motion Tween in a new way: to animate the opacity of the fireworks burst. We’ll animate them fading in and then fading out over the same time period that they grow and shrink; that means that we’ll need the fireworks layer to last for 24 frames.
