■ TRIMMING METHODS
Trimming on the Fly
Trimming on the fly is a simple yet elegant way to adjust a transition based on timing
with real-time playback. It is based solely on your ability to react as the sequence is
played back. When you trim on the fly, the transition loop plays, and you “tell” the
transition where to move by pressing a Mark In or Mark Out button on the keyboard
(see Figure 5.11). It doesn’t matter which Mark In or Mark Out button that you use,
as long as it is located on the keyboard. The keyboard equivalents on a standard
Xpress Pro and Free DV system are the E, R, I, and O keys.
To trim on the fly, enter Trim mode and select the transition side(s) and tracks to
be trimmed. Play back the trim loop. Before attempting to trim on the fly, you might
want to let the loop play back a couple of times so that you can get a feel for the tim-
ing of the transition. Otherwise, you could trim incorrectly and have to undo every-
thing. As the loop plays continuously, select the point where you want the transition to
move by pressing the E, R, I, or O key. The transition point moves accordingly. If you
did not select the appropriate point, let the loop continue to play back and reselect, or
press Ctrl-Z/F-Z to undo and then continue playback.
If you need to trim past the loop, change your trim settings to reflect a longer
preroll or postroll for the trim loop. By doing this, you will give yourself more space
in which to make the trim. It also gives you more a bit more “breathing space” while
you’re attempting to find the correct point for the transition.
Trimming on the fly is normally used for trimming to a precise moment in music
or in action. Although it could be said that there are more precise methods, many edi-
tors pride themselves on their sense of timing, just as they do in knowing frame counts.
Trimming on the fly is a great exercise in creative freedom, and when an editor has
good reaction time, it produces great results.
Trimming on the fly takes a little practice before you get used to it. A common
mistake when trimming on the fly is to trim too far, obliterating almost all of either the
A-side or B-side clip. Sometimes undoing the trim is better than spending time trying to
resurrect the partially missing clips. Don’t waste time! Undo the trim and try trimming
it again.
J-K-L Trim (Xpress Pro Only)
J-K-L trimming is one of Xpress Pro’s best features and is, in my opinion, the best rea-
son to upgrade from Free DV to Xpress Pro. (Note to Avid: Mail the check. Repeat:
Mail the check.) Actually, it really is an excellent method, and no, Avid didn’t pay me
