Apple Final Cut Pro 7 - Manual (Page 118)

As you scrub through your clip or sequence, audio also plays back more quickly, but it
doesn’t play back smoothly—it will seem to stutter (not speed up) as individual audio
samples are skipped. This is normal. For smooth playback of audio at speeds under 1x,
use the shuttle control instead.
To scrub through a clip or sequence

To move around, drag
the playhead along the

You can also use the scrubber bar to jump to a different part of your clip or sequence
instantly, without playing all the footage between the previous location of the playhead
and the new location.
To jump to a new location in the scrubber bar
µ
Click the desired location in the scrubber bar.
Shuttling Through a Clip or Sequence
While using the scrubber bar is a great way to quickly navigate to different parts of your
clip or sequence, sometimes you want to play through your clip or sequence smoothly
at varying speeds as you make decisions about where to place your edit points. The
shuttle control gives you this kind of smooth control, playing back your video and audio
at various speeds in either direction, much as the shuttle of a video deck does.
In particular, the shuttle control is useful for playing back at less than 1x speed. As the
audio slows down, it’s sometimes easier to distinguish individual words, and to set your
In and Out points more accurately.
The shuttle control can play your clip or sequence at five speeds in each direction: 1/4x,
1/2x, 1x, 2x, and 4x. The shuttle control snaps to the closest available speed. When the
shuttle control is at 1x speed, or 100 percent, the slider turns green.
To play clips or sequences at varying speeds using the shuttle control
µ
Drag the shuttle slider to the left or right.
