Scrolling During Playback uses host processing
power, so use this option with Pro Tools LE with
Complete Production Toolkit or DV Toolkit 2
only when absolutely necessary.
Center Playhead Scrolling
(Pro Tools HD Only)
When this scrolling option is selected, the Edit
window’s contents scroll continuously past the
Playhead, which is a blue line in the center of the
window (or a red line when recording).
The Playhead indicates where playback begins
when clicking Play in the Transport window.
To move the Playhead to a particular location
for playback, you can scroll there in a ruler (see
“Scrolling in a Timebase Ruler” on page 487),
use the Edit window’s horizontal scroll bar, or
type the location into one of the Edit Selection
indicators or one of the Counters.
Moving the Playhead with these methods does
not update the Timeline selection. However, up-
dating the Timeline selection automatically
moves the Playhead to the Timeline insertion
point.
With the Playhead enabled, you can jump to
and play an Edit or Timeline selection. For de-
tails, see “Playing Timeline and Edit Selections
with the Playhead” on page 337.
Half-Screen Edit Window
When the Scrolling option is set to Continuous or
Center Playhead
, a half-screen appears at the far
left of the Edit window (before the beginning of
the session) when the Playhead is at the begin-
ning of the session.
Playing Selections
Once an Edit selection is made, you can audi-
tion it by clicking Play in the Transport window.
If enabled, the pre- and post-roll amounts play
as well.
To play a selection:
1 Select Options > Link Timeline and Edit Selection.
2 With the Selector or Time Grabber tool, make
a track selection.
3 If you want to use pre-roll or post-roll, enable
and set the pre-roll and post-roll amounts. For
details, see “Setting Pre- and Post-Roll” on
page 376.
Center Playhead Scrolling option
Center Playhead Scrolling and Dynamic
Transport mode cannot be used at the same
time. Selecting Center Playhead Scrolling
disables Dynamic Transport mode (if it is
enabled). Likewise, enabling Dynamic
Transport mode when Center Playhead
Scrolling is selected automatically changes
the Scrolling option to No Scrolling.
