■ TRIMMING METHODS

Adding Rollers

After you enter Trim mode and have selected which side of the transition is to be

trimmed, you might have noticed some pink rollers at the transition point in the Time-

line. These rollers can be clicked and dragged to adjust the trim interactively on the

Timeline with your mouse. Although using this method isn’t as accurate as numerical

entry or the trim buttons described later, grabbing and dragging the rollers will update

the monitors, providing feedback as you trim. You can also add and subtract rollers by

Shift-clicking additional tracks.

Using the rollers can be a little hazardous. At first, you might accidentally click

on the wrong side of the transition and create a roller on the opposite side of the tran-

sition that you intended to trim. When this happens, move the mouse a little more pre-

cisely and try clicking again. If you inadvertently moved the mouse and trimmed some

frames on the wrong side, release the mouse and undo the trim (Ctrl-Z/F-Z). The

click-and-drag method with rollers is used primarily for shorter trims, in which only a

few frames need to be added or subtracted from the transition.

You can also add rollers at different transitions. For example, if you’re trimming

a split edit, in which the audio transitions one place and the video transitions in a dif-

ferent place, you can Shift-click to trim both audio and video, even though they transi-

tion at different points in the sequence.

You can also add rollers by lassoing a transition.

Button Trimming

The Trim interface uses buttons for adjustment of a transition, both on the interface and

on your keyboard. These buttons, shown in Figure 5.9, are mapped to the interface

under the Source monitor. They are also mapped on the default Xpress Pro keyboard.

Note: If you have a high resolution set on your monitor, you might consider downsizing it a bit to better

see the trim rollers when you go in close to examine a transition.This also helps you see flash frames and other

hazards when trimming.Another alternative is to zoom into the Timeline using the keyboard (Ctrl-[/F-[), the

arrow up and down keys,or the scroll bar at the bottom of the Timeline.
