CHAPTER 4: THE TIMELINE ■

After the sample rate is established, you might encounter a tape that has a lower

sample of audio recorded. In these cases, it is essential that you select Always for sam-

ple conversion. If you select Never, the system will inform you that the tape has the

wrong audio sampling rate, and it cannot be played. This selection has to be done if

any sample rates differ from the one that you have established. If you always select

sample rate conversion, you will be asked to upsample the lower rates when you do

your output.

Timeline Editing

When Avid first introduced the Timeline editing functions, I thought it was a waste of

time and a kid’s toy. All that silly clicking and dragging! A real editor wouldn’t need

anything more than a Source/Record interface.

Once again, I was wrong. The Timeline editing functions do a lot more than

clicking and dragging. With Timeline tools, you can move, adjust, juxtapose, and delete

portions of your Timeline. In fact, I now find it indispensable.

Let’s start off by looking at the Timeline editing tools. There are only two of

them, but each does a lot.

Lift/Overwrite Mode

The Lift/Override button does two things: It lifts the selected segment on the Timeline,

leaving a “black hole” or filler where the segment was previously positioned, and it

overwrites the video at the exact point in the Timeline where it is moved. The conse-

quence of overwriting here should be noted—it’s severe. It’s sorta like that movie where

they overwrote a house on the Wicked Witch of the East.

Here’s an example of how that process can work. We’re editing a montage. So

far, we have edited shots A, B, and C. Now the director says that you should move

shot B so that it is located after shot C. He wants to put something else in the place

where shot B was located. Here’s how to do it:

Click the red Lift/Overwrite button at the bottom of the Timeline (see Figure 4.24).

2. Click the B shot.

3. Press Ctrl/F and drag it so that it will be placed after shot C. Using Ctrl/F moves

the selection to the beginning of each segment on the Timeline. Otherwise, you

have to approximate where the segment would go, which can result in flash frames.

The result is that the previous location of shot B is opened up, and now the clip

formerly known as shot B has become shot D. If you chose to move your selection to

where shot C begins, shot B would replace shot C.
