LESSON 8
Applying Specialized Editing Tools
Using Sync Lock and Track Lock
In a typical editing project, you will have multiple layers of video clips. When you 
edit a sequence by doing ripple edits or inserts, you’ll want all the video tracks to stay 
in sync. This means if one track moves, all the other tracks move the same amount.
However, sometimes you may want one track not to move when you’re performing 
ripples or inserts. Adobe Premiere Pro provides two methods of protecting one or 
more tracks from being moved: Sync Lock and Lock Track.
Using Sync Lock
Let’s start by trying the Sync Lock feature:
1
Open Lesson 08-03.prproj. Note that this sequence has four video tracks with 
a gap between clips.
2
Right-click (Windows) or control-click (Mac OS) the gap between clips on the 
Video 1 track, and choose Ripple Delete.
The clips on the right move left to close the gap.
3
Press Ctrl+Z (Windows) or Command+Z (Mac OS) to undo the ripple delete.
