Putting Clips in Motion

LESSON 10

Working with keyframe interpolation: Lesson 10-3

 e Motion e ect moves clips through the screen over a period of time. Premiere Pro

o ers Keyframe Interpolation methods that suit both aspects of that motion: Spatial

and Temporal.

Spatial Interpolation refers to the motion path—where the clip will appear on screen.

Temporal Interpolation refers to changes in velocity.

When you worked with non-motion e ects—Fast Blur, Wave Warp, and Replicate, for

example—you worked with Temporal Interpolation in the Velocity and Value Graphs in

the E ect Controls timeline.  e e ects you’ve worked with generally haven’t had screen

location parameters so Spatial Interpolation has not been an option (Lightning is one

exception—its start and end points can have spatial and temporal interpolation).

 e focus for this lesson is Motion’s Position parameter. It has a Spatial Interpolation

option that you will likely use time and again. You won’t  nd it in the E ect Controls

panel. It’s in the Program Monitor.

1 Expand the View Zoom Level in the Program Monitor back to the default—Fit—and

expand the Program Monitor’s frame to get a better look at the keyframes.

2 Drag the Lesson 10-3 Preset to the clip.

3 Drag any keyframe handle in the Program Monitor.  at will change the motion

curve—the Spatial Interpolation—but will not convert the keyframes in the E ect

Controls timeline into Bezier curves (their icons remain diamonds).

4 Right-click on any keyframe in the Program Monitor and select Spatial

Interpolation > Linear.

 at changes the motion lines at that keyframe into straight lines and sharp angles

(they’ll start curving as they approach a keyframe with Bezier Spatial Interpolation).

5 Right-click on any keyframe in the Program Monitor and select Temporal

Interpolation > Auto Bezier (or any other Bezier Interpolation method).

 at changes the Temporal Interpolation keyframe in the E ect Controls panel into a

Bezier curve.

Note:  e keyframe in the Program Monitor does not switch to a Temporal Interpolation

keyframe. It remains Spatial. To change the temporal characteristics of the keyframe

selected in the Program Monitor, you need to drag its handles in the E ect Controls

Velocity Graph.
