Changing the speed of multiple 
clips simultaneously
Adobe Premiere Pro CS5 has the ability to change the speed of multiple clips at the 
same time.
1
Continuing where you left off with Lesson 11-6.prproj, press Ctrl+Z (Windows) 
or Command+Z (Mac OS) to undo any speed changes.
2
Select all three video clips in the Video 1 track by Shift-clicking each one.
3
Right-click (Windows) or Control-click (Mac OS) any of the selected clips, and 
choose Speed/Duration from the context menu. Change Speed to 50%, and 
click OK.
All three video clips now play at 50 percent speed, but only the last clip expanded 
in length. This is because the last clip was not constricted by any other clips.
#
 Note:
Since all 
the video tracks have 
Toggle Sync Lock 
enabled by default, 
all tracks shift (stay in 
sync), not just the track 
with its speed being 
adjusted.

Changing the length of multiple 
stills simultaneously
Although a still image does not really have a speed, it does have a duration. 
Adobe Premiere Pro CS5 allows you to adjust the duration of any group of 
selected still images.
1
Open Lesson 11-7.prproj. Notice that the Timeline is full of still images of 
sunsets. The duration of all the images is five seconds, and there is a Cross 
Dissolve transition between all of them.
