Apple Final Cut Pro 7 - Manual (Page 114)

114 Chapter 5 Basic Editing
The left side of the window shows the Out point of the outgoing clip. The In point of
the incoming clip appears on the right side of the window. You can drag the In point or
Out point markers to change them. You can also move the playheads on either side of
the Trim Edit window and click the Mark In and Mark Out buttons to move the In and
Out points to the location you want.
Click in the left side of the window to select it, and a green outline appears, indicating
that you’re editing the Out point. Any change to an Out point ripples the following
clips forward or backward without creating a gap. Click in the right side of the window
to change the In point of the incoming clip, rippling the clips so that no gap is created.
You can also click the center of the window to select both sides of the Trim Edit
window at once. You can then change both the Out and In points by the same amount,
rolling the edit point left or right.
Feel free to experiment and familiarize yourself with the Trim Edit window. After you’ve
used it some and are acquainted with how it works, you’ll find it an ideal way to move
through a sequence and apply final trimming decisions.
