CREATING THE FADE-IN
A1) While still in myMosaic symbol, go to frame 1, hide one of the layer, then click the checkerboard and get
the Effect window (Window > Panels > Effect). Set the Alpha
A2) Do the same with the checkerboard on the other layer (set Alpha to
0). By doing this, when the movie is running, the Alpha will be tweened
form 0 to 100, creating the effect that the image fades-in gradually.
A3) We need to alter the speed of the tween so that both checkerboard does
not appear at the same time. Let's move the key frame of the second
checkerboard to frame 7. (Make sure to click the key frame first before
dragging, if not, you won't be able to drag it.)
So the layers become like this:
A4) Go back to Scene 1, then drag an instance of myMosaic into the stage.
Set behavior to Movie Clip. Then test the movie.
CREATING THE FADE-OUT
If you understand what has been done in the previous step, this is very
easy. Basically, you can create all sorts of interesting effect by
altering the Alpha, Brightness of the symbol in different key-frames (i.e.:
frame 1 and frame 30 above). The tween calculates the difference between
each frame. For example: In Layer1 above, the Alpha value of the
checkerboard changes gradually from 0 (invisible) to 100 (fully visible).
To create fade out, we can reverse the process, so that Alpha goes from 100
to 0. But you can also change the brightness of the symbol to create more
interesting effect. Here's the setting that I use for the example movie
