Continuous Scrolling During Playback
(Pro Tools HD and Pro Tools LE with
DV Toolkit 2 Only)
When this scrolling option is selected, the Edit
window’s contents scroll continuously past the
playback cursor, which remains in the center of
the window. With this option, playback is al-
ways based on the Timeline selection (unlike
the Center Playhead Scrolling option). Continu-
ous Scrolling During Playback uses host process-
ing power, so use this option with Pro Tools LE
with DV Toolkit 2 only when absolutely neces-
sary.
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 (red 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 393),
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 412.
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).
Linking or Unlinking Timeline
and Edit Selections
Pro Tools lets you link or unlink the Timeline
and Edit selections.
When the Timeline and Edit selections are
linked, selecting in a track’s playlist (making an
Edit selection) also defines the play and record
range (the Timeline selection).
Unlinking Timeline and Edit selections lets you
make a selection within a track for editing pur-
poses that is distinct from the selection in the
Timeline (which determines the playback and
recording range).
