CHAPTER 5: TRIMMING ■

To extend, select the track(s) you want to extend. Find the point in the sequence

to where you want to extend the clip. If this point is before the edit, mark an in

point (see Figure 5.18). If it is after the edit, mark an out point. Click the Extend

button, which is mapped to the P button on your keyboard. The edit is extended in

the Timeline.

Extend edit is an excellent way to perform split edits of L cuts (also known as

split edits). After an audio-plus-video edit is made, select the track you want to trim,

mark your point, and hit the Extend button on your keyboard. This process is very fast

and intuitive.

Extend can be a little hazardous to use because if you have both an in point and

an out point marked, Avid uses the in point as the higher priority. Why is this danger-

ous? If you mark an out point near the transition that you intend to extend, and you

have an in point marked at some far-flung location on your sequence, pressing Extend

will not do what you intended. Instead, some transition that you aren’t even paying

attention to will become extended by accident. To prevent this, you can always press

the Clear Marks button before marking an edit for an Extend.

The method that I use to quickly determine the direction of the extension is to

remember that the rounded part of the Mark In or Mark Out button must be facing

the transition in the Timeline.

Maintaining Sync

It seems that whenever a new tool is introduced that can do powerful things, there is

an issue of the dangers associated with it. In the case of trimming, constant attention

must be paid to avoid breaking sync.

Avid has developed a tool to help: Sync Breaks. Whenever a clip with audio and

video is adjusted so the tracks become out of sync, the number of frames out of sync

appears on the Timeline (see Figure 5.19).
