In-Depth Information
The animation includes a reduction of the Z Jitter Amount
property to make these cards gather back together again. The
purpose of this is to then fl ip the gathered cards over and have
the logo for the TV show be on the backside of the cards. In the
Card Wipe effect controls on the Photos.psd layer, make sure that
the Back Layer value (which determines what is on the backside
of the card) is set to the Animal Discoveries comp layer. It's best
to leave the visibility of the actual layer used as the back layer off
in the Timeline panel. Then, when the cards have gathered, ani-
mate the Transition Completion value from 0% to 100%. When it's
all said and done, you have a cool show opener. Note that in this
comp, I've also allowed the slightest amount of position jitter by
taking the jitter speed values to 0.1 for all dimensions. This set-
ting will allow these cards to slowly wiggle randomly. This creates
the sense that these cards are wild and untamable, like animals
(Fig. 20.15 ).
Figure 20.15 After the cards
have gathered, you can fl ip them
to the Animal Discoveries logo
by selecting it as the Back Layer
and animating the Transition
Completion property.
The Gradient Wipe Effect
The Gradient Wipe effect uses a gradient to determine the
order the pixels are removed from the top layer to reveal the
bottom layer. Because you can actually create some innovative
transitions using the Gradient Wipe effect, I've created a project
for you to use to experiment with this effect. It's called Gradient
Wipe.aep, and you'll fi nd it in the Chapter 20 folder of the exer-
cise fi les.
This project contains the same basic magenta and green solids
we'll be looking at in this chapter; but it also contains a couple
of layers that we'll use to control the transition. The fi rst control
layer we use is a simple gradient created with the Ramp effect
(discussed in Chapter 9 ) (Fig. 20.16 ).
