Changing clip size—
like working with text
As you did in the Titler, you can change clip size by using the bounding box. 
Deselect Uniform Scale; then, to scale freely, drag a corner handle. To scale one 
dimension only, drag a side (not a corner) handle; to scale proportionally, Shift-drag 
any handle.
10
Play this clip.
The clip should grow from a tiny dot in the upper left, move to full-screen in 
the center, hold there for a while, and then shrink to a dot while moving to the 
lower-right corner.
Adding rotation and changing the anchor point
Now you’ll add some rotation to the clip:
1
With the Timeline active, press Page Up or Home to move the current-time 
indicator to the beginning of the clip, and click Rotation’s “Toggle animation” 
button.
That sets a keyframe for Rotation with 0.0° as the starting point.
2
Click the Go to Next Keyframe button next to either Position or Scale to move 
the current-time indicator to the second keyframe.
3
Hover the pointer just outside a handle of the bounding box in the Program 
Monitor until it becomes a curved double-arrow pointer, and then drag the 
bounding box clockwise two full rotations, as shown here.
#
 Note:
You can 
fine-tune this move 
in the Effect Controls 
panel by setting 
Rotation to 2x0.0°.

LESSON 10
Putting Clips in Motion
4
Move the current-time indicator to the third keyframe, and click the Rotation 
Add/Remove Keyframe button. That adds a keyframe with the same value as the 
preceding keyframe.
5
Move the current-time indicator to the end of the clip.
6
Click the Rotation disclosure triangle to expand the Rotation parameter, and 
drag the Rotation circle counterclockwise twice. Note that you can’t use the 
Program Monitor bounding box to adjust Rotation because the clip has been 
shrunk to a point.
That returns Rotation to its default setting of 0.0°. If you can’t see the keyframe 
graphs, expand the Scale and Rotation parameters. Play this clip. It will rotate 
clockwise twice, hold, and then rotate counterclockwise.
7
Play this effect. It should look similar to the effect in the Finished sequence. A 
difference between this effect and what you see in the Finished sequence is that 
the rotation suddenly stops and starts. You’ll fix that next.
If you like the effect, you can save it as a preset. Right-click (Windows) or 
Control-click (Mac OS) the Motion effect, and choose Save Preset.
