Adobe Premiere Pro CS5 - Classroom in a Book

Using other motion-related effects: 
Transform, Basic 3D and Camera View
Adobe Premiere Pro has several effects with some shared functionality, with subtle 
differences that dictate their respective use. In this section, you’ll learn the differ-
ences between the Motion and Transform effects and between the Basic 3D and 
Camera View effects.
Transform
Let’s start with Motion and Transform.
1
Open Lesson 10-4.prproj, and open the Motion and Transform sequence. As 
you’ll see, there are two sets of two videos on the Timeline. Drag the current-
time indicator over both to quickly view the content. Note that the Mac version 
of Premiere Pro CS5 doesn't have the Camera View filter, so you’ll get an error 
message. 
In both cases, a picture-in-picture is rotating twice over the background clip, 
while moving from left to right. Look carefully at the relationship of the shadow 
to each pair of clips. In the clips on the left, the shadow follows the bottom edge 
of the PIP and therefore appears on all four sides of the clip as it rotates, which 
obviously isn’t realistic because the light source produces the shadow and it isn’t 
moving. In the set on the right, the shadow stays on the lower right of the PIP, 
which is realistic.
2
Click the top clip of the set on the left, and view the effects applied in the Effect 
Controls panel: the Motion fixed effect and Drop Shadow effect. Now do the 
same for the pair on the right; you’ll see that the Transform effect is producing 
the motion, with the Drop Shadow effect again producing the shadow.

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.
3
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.
4
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.
