CHAPTER 5: TRIMMING ■

Trimming Mathematics

I so loathe telling people that some mathematics is involved, because it can send many

an editor running. But the math is very simple. Let me repeat what I just described:

When you trim negative on the A side, you are reducing the number of frames. Con-

versely, if you trim negative on the B side, you are adding frames. That’s because the

“roll of carpet” on the B side is at the head of the frames, not the tail, as it is on the

A side. On the other hand, when you trim positive on the A side, you add frames.

When you trim positive on the B side, you are subtracting frames.

To conclude (and reiterate):

• When you roll forward on the A side, you are extending the outgoing shot.

• When you roll backward on the A side, you are reducing the outgoing shot.

• When you roll forward on the B side, you are reducing the incoming shot.

• When you roll backward on the A side, you are extending the incoming shot.

If you comprehend these simple rules, the rest is a piece of cake. If you still don’t

get it, experience will teach you, so don’t worry.

Trimming Methods

At first sight, the number of trimming methods can be overwhelming. But before you

get nervous, I should note that the reason for so many different methods of trimming is

that there are so many different reasons that you’ll need to trim. Additionally, some

editors prefer to trim using only one method. When Avid developers created the Trim

tool, they consulted with a lot of different editors who use a lot of different styles.

Here are some examples of trim methods you might use: If you’re cutting dia-

logue and need to match eyelines, there is one particularly good way to trim. (For sake

of clarity, the eyeline is the direction in which an actor is looking in opposition to other

actors in a scene.) For cutting music videos, there is another different method for trim-

ming that is very efficient. For compiling a sequence of animation, there is still another.

So as you learn each of these methods, keep in mind that you don’t have to learn them

all at once, and there is no best method.

Note: When Caps Lock is activated, the system will scrub audio as you trim,so that you can listen for

audio cues.
