Use care not to lose your video and audio synchronization when trimming. Instead of
dragging, you can enter values in the Start and End boxes at the top of the Track Editor

and End boxes.

Select the clip you want to trim.
The clip appears in the Clip Inspector.
Enter a new Clip Start Offset to trim the clip’s start.
The clip’s start position on the timeline is not changed—only its end position is moved
to match its new duration.
Enter a new Duration value to trim the clip’s end.
