Because of the fl exibility of this value, you can create some
very interesting results by applying a wiggle expression to it. If
you want to make a surface boil or to have other random distor-
tions, this might be the fastest way to do it.
Using Freeze Area
When using the
Liquify effect, there
might be some
pixels that you absolutely
don't want to change in any
way. In that case, create a
mask around them. Then
in the Warp Tool Options
area of the Liquify effect in
the Effect Controls panel,
choose the mask you
created from the Freeze
Area Mask drop down.
The Magnify Effect
The purpose of the Magnify effect is to make a portion of an
area larger, without the spherical distortion that we see in the
Bulge and Spherize effects. This effect is used to zoom in to a par-
ticular area, which is great for demonstrating products in mar-
keting ads or for the medical/biological fi eld, where things often
need to have a closer look.
If you'd like to follow along, I'll be using the Magnify.aep proj-
ect in the Chapter 9 folder of the exercise fi les. In the example
given here, I've created a magnifying glass (out of two shape lay-
ers and some layer styles), and we also have an Artbeats video
clip of a city fl yover on another layer (Fig. 7.31).
Figure 7.31 The Magnify.aep
We're going to use the Magnify effect to magnify the Artbeats city
footage. We're going to create the illusion that we're doing some
spy-esque reconnaissance work on some of the people in these
buildings. We'll match up the size of the magnifi ed area to the glass
in the magnifying glass. Then we'll connect them using expressions
so that we can just move the magnifying glass around (or animate
it doing so) to see different parts of our footage magnifi ed.
Apply the Magnify effect to the Artbeats footage on the layer. Before we play around with the magnifying
glass, let's turn off the magnifying glass layer to just see what the
