Layer Transitions
A Layer Transition is an effect that controls how the layer appears or
disappears. These work just like transitions between slides, except that they
can be applied to each layer within a slide, separately from the slide
transition.
By default, the transition type for all of your layers will be a Cut.
If you click on that transition icon, you will open the Transition
Chooser window. Notice that this is slightly different window
you use when setting slide transitions, as only certain effects
are available for layer transitions.
When you pick a transition for a layer that happens over time, a crossfade
for example, you get a time indicator associated with that keyframe. You
can adjust the time of the transition by dragging the bar that appears in the
middle of the keyframe timeline at the end of the transition effect.
Layer Transitions work just like slide transitions, controlling how the layer
fades in or out. There are two differences between slide and layer
transitions. The first is that the slide transition affects everything in a slide,
while layer transitions only affect the layer they are applied to.
The second is that layer transitions can only use certain transitions, which
will exclude some built-in transitions as well as any transitions you have
created or installed separately.
You can create some very interesting effects by applying layer transitions to
special layers like masks or adjustment layers.
