■ TRIM SELECTION

I liken this scenario to rolling out carpet. Think of the pink rollers in your Time-

line as little rolls of carpet. When you are trimming backward on the A side of a transi-

tion, the carpet rolls back before the transition, thus subtracting frames that occur

before the transition. If you trim forward on the A side, you roll the carpet forward,

adding more frames to the transition.

B-Side Source Trimming

Trimming the B side of an edit (see Figure 5.7) adds or reduces the amount of footage

in the incoming scene. Using the previous analogy, the B-side carpet roll is located at

the beginning of the incoming cut, and the tail of the carpet continues in front of it. So

if you trim forward on the B side, you are rolling up the carpet and making the B-side

clip shorter. If you roll backward on the B side, the carpet is rolling backward, thus

adding more frames.

Trimming Both Sides

You enter A/B Trim mode by clicking between your Source and Record monitors.

There is a scroll icon that appears when you move the mouse. When this icon appears

to have two sides, click the mouse and you will be in A/B Trim mode. Notice that the

pink rollers appear on both sides of the transition in the Timeline (see Figure 5.8).
