One effect in this category stands out above all the rest—Card
Wipe. This effect splits up a layer into a series of cards that can
fl ip and move in three dimensions. Card Wipe is quite powerful
(especially for a transition), allowing you to control the naviga-
tion of the effect with composition cameras and lights, and con-
trol how the cards react to light with material options. It's also
the last effect that we'll be looking at that was designed by After
Effects guru and legend Brian Maffi tt.
Throughout this chapter, when looking at the simple transi-
tions (i.e., everything except Card Wipe), we'll be using a couple of
simple contrasting solids so it's clear what each transition is doing.
The green solid will be the layer on the bottom, or in other words,
the layer we'll be transitioning to. The magenta solid will be the
layer on top, and it's the one that we'll be applying the transition
effects to. We'll also be using two video clips to test these transi-
tions—the one on top is of Seattle, and the video clip below is from
Artbeats and depicts two children running (Figs. 20.1 and 20.2 ) .

The Block Dissolve Effect
The Block Dissolve is fairly simple, but it needs a little help to
be useful. Its default settings look like a layer using the Dissolve
blend mode (that's bad). The purpose of this effect is to transition
to transparency by removing the layer in blocks. There are only a
