Chapter 9

Question 1

In which pan and section do you change the speed of a clip?

Answer 1

The Properties Inspector in the Timing pane.

Question 2

Name the two kinds of Time Remap speed changes.

Answer 2

Constant Speed and Variable Speed

Question 3

Identify three of the four frame blending options.

Answer 3

None, Blending, Motion-Blur Blending, and Optical Flow

Question 4

You created a slow motion effect using the Optical Flow option. How can you determine the size of the resulting cache file?

Answer 4

Choose Motion > Preferences. In the Cache pane, click the “Reveal In Finder” button, and then select the cache file to view its properties.

Question 5

Can you continue working on a Motion project while the optical flow analysis is performed?

Answer 5

Yes, it’s a background task.

Question 6

Describe four reasons to create a speed effect with a Retiming behavior instead of using keyframes.

Answer 6

Behaviors can be added and adjusted quickly; they can create effects that would be difficult or time-consuming using keyframes; Retiming behaviors only change the parts of a clip to which they are applied; you can change the locaitons and durations of Retiming behaviors in the mini-Timeline.

Question 7

Which Retiming behavior lets you create a speed ramp effect?

Answer 7

The Set Speed behavior

Question 8

Can you combine Retiming behaviors with keyframes?

Answer 8

Yes, if you apply a keyframe curve to a Retiming behavior, both keyframes and behaviors manipulate the clip’s playback speed.

Question 9

Name two of the Time filters.

Answer 9

Echo, Scrub, Strobe, Trails, Wide Time
