1
Undo your changes until you have the clip at its original speed at six seconds. 
(As an alternative, you can reopen Lesson 11-1.prproj.)
2
Right-click (Windows) or Control-click (Mac OS) the Medieval_Hero_01 clip, 
and choose Speed/Duration from the context menu.
3
Set Speed to 300%, click the link icon so Speed and Duration are linked, and 
then click OK.
4
Play the clip. Notice its new length is two seconds. This is because Speed is set 
to 300%—or three times its normal speed.
#
 Note:
The Clip 
Speed/Duration dialog 
shows a Maintain Audio 
Pitch option if the clip 
has audio. Selecting 
this option keeps 
audio at the original 
pitch regardless of 
the speed at which 
the clip is running. 
This can be helpful 
when making small 
speed adjustments to 
clips when you want 
to maintain pitch in 
the audio.

LESSON 11
Changing Time
Changing speed with the Rate Stretch tool
Sometimes you’ll need to find a clip that’s just the right length to fill a gap in your 
Timeline. You might be able to find the perfect clip, one that’s exactly the right 
length, but most times you will find a clip you want to use that is just a little too 
short or a little too long. This is where the Rate Stretch tool comes in handy.
1
Open Lesson 11-2.prproj and preview the Timeline.
The situation in this exercise is fairly common. The Timeline is synchronized 
to music and the clips contain the content you want, but the clips are just too 
short. You can guess and try to insert just the right Speed percentage in the 
Clip Speed/Duration dialog, or you can use the Rate Stretch tool to drag the clip 
to the needed length.
