CHAPTER 5: TRIMMING ■
In other cases, we might trim both sides at the same time. For example, if we
roll the A side forward, we roll the B side forward as well. The A side is adding frames
as the B side is inversely losing frames.
Are we lost yet? Hopefully not, but don’t worry. With a little practice, you’ll
completely understand trimming.
The Trim mode is one of three modes used in Avid editing:
• Source/Record mode, in which we perform basic editing functions
• Trim mode, in which we analyze and adjust the edit
• Effect mode, in which effects are added to enhance the sequence
Most editors prefer this very simple “modal” type of editing because it reduces
the clutter of excess functions and allows you to focus on the work to be done. Other
editing systems brag about being nonmodal; I never understood why that would ever
be considered a feature.
Let’s go to Trim mode! (See Figure 5.2.) Here’s all you do. Press the button that
looks like a little 35mm film can located underneath the Record monitor on the left
side. An alternative way to instantly enter Trim mode is to lasso a transition on the
Timeline by using your mouse (see Figure 5.3). This procedure switches the GUI from
Source/Record mode to Trim mode for that transition, using the tracks that were las-
soed. To exit Trim mode, either click the Trim Mode button again, or press Escape on
your keyboard.
