9
Click the practice sequence to make it active.
10
Drag the Medieval_wide_01 clip to the Video 1 track of the practice sequence.
11
Right-click (Windows) or Control-click (Mac OS) the clip, and choose Scale to 
Frame Size to scale the clip to match the sequence resolution.
12
Drag the nested practice sequence to the Video 2 track, directly above the 
interview clip. Make the clip in Video 1 the same length as the nested practice 
sequence in Video 2.

LESSON 16
Working with Color, Nested Sequences, and Shortcuts
13
With the nested practice sequence clip selected, add a Scale keyframe in the 
Motion effect at about three seconds from the beginning of clip. Set its value to 
80. Set another Scale keyframe at the beginning of the clip, and set its value to 0.
14
Set a keyframe for the Rotation parameter in the Motion effect at the beginning 
of the clip. Set its value to –4x0.0. Set another Rotation keyframe at the same 
point in the Effect Controls Timeline as the second Scale keyframe. The 
keyframes snap to each other to make this easy. Set the value of this Rotation 
keyframe to 0.0.
15
As a nice touch, you can right-click (Windows) or Control-click (Mac OS) the 
last Rotation keyframe you set and set it to Ease In.
This will make it gradually stop rotating, rather than stop suddenly.
16
Play the clip.
The power of nesting allows you to apply effects to multiple clips at once by nesting 
clips in a sequence. You can also nest sequences in sequences.
In the previous exercise, you nested an entire sequence in another sequence. It’s 
also possible to select a group of clips and nest them in a sequence. It does not have 
to be all the clips in a sequence. This can be useful for collapsing a complex set of 
clips into a single nested sequence.

Open Lesson 16-4.prproj, and double-click the completed sequence to open it 
in the Timeline. Play the Timeline.
We will create a Cube Spin transition at the edit point of the Medieval_wide_01 
clip and Medieval_villain_02. Since there are two other clips composited over 
the Medieval_wide_01 clip, inserting a Cube Spin transition that correctly 
impacts the first three clips is difficult—but not if you collapse the first segment 
to a single nested clip.
