ADOBE PREMIERE PRO CS5 CLASSROOM IN A BOOK

In the screen comparison shown here, you can see that the Transform effect
has many of the same capabilities as the Motion fixed effect but also adds Skew,
Skew Axis, and Shutter Angle. As you just saw, the Transform effect
also works
more realistically with the Drop Shadow effect than the Motion fixed effects.

Observe the render bar above both sets of clip. If you have a Mercury Engine–
compatible graphics card in your system, you’ll note that the render bar is
yellow on the left and red on the right.
This tells you that the Motion effect is GPU-accelerated,
which makes
previewing and rendering more efficient, while the Transform effect isn’t.

Click the top clip on the right. In the Effect Controls panel, drag the Drop
Shadow effect
above
the Transform effect, and drag through the pair of clips
on the right again.
Note how the shadow now follows
the PIP around as it rotates, which isn’t the
realistic look that you want. The order in which effects are listed matters, and
different orders will often produce different results. When applying multiple
effects to a clip, if you’re not getting the look you want,
drag the order around
and see whether that produces the desired result.
