196 LESSON 10
Putting Clips in Motion
Creating a picture-in-picture effect The PIP technique is one of the most common uses of the Motion effect. It’s also
one of the easiest ways to see how you can
composite , or layer, clips. You will begin
formal work on compositing later in the book. This exercise will give you a taste.
To simplify things, you’ll start with a sequence that has five layered clips in it, all ready
to go. You will create PIPs and add drop shadows and beveled edges to the PIPs.
1 Open Lesson 10-3.prproj; then open the Finished sequence by double-clicking it
in the Project panel, if it is not already displayed. Render and play that sequence
to get an idea of what you can do.
You should see five PIPs, each with a drop shadow and beveled edge.
2 Open the Practice sequence by double-clicking it in the Project panel.
If you play this, you will see only the clip on the top track. It covers all the clips
below it in the sequence.
3 In the Effects panel, expand Presets so you can see Effects > Presets > PiPs >
25% PiPs > 25% LR.
Note the following:
t All the PIP presets display clips at 1/16th their normal area (reminder: the
25% refers to clip perimeter, not area).
t LL, LR, UL, and UR refer to screen locations: lower left, lower right, upper
left, and upper right.
t Each PIP set offers different types of PIP moves.
t Typically, you select a style and then adapt it to your needs. For example,
you might change the preset start or end locations or the size.
The clip in the Video 1 track will remain as is; you want to use it as
a background.
#
Note: There is no
25% Center preset. You
use one of the presets
to create one. Simply
change the start and
end Position keyframes
to 360, 240.
