Main Time Scale
While all Timebase rulers can be displayed si-
multaneously in the Edit window, there is only
one that represents the Main Time Scale. This
ruler is also called the Main Timebase ruler.
The Main Time Scale determines the time for-
mat used for:
• The Main Counter in the Transport win-
dow
• The Main Counter at the top of the Edit
window
• Start, End, and Length values
• Pre- and post-roll amounts
• Grid and Nudge values
The Main Time Scale can be set to the following
formats:
Bars:Beats Displays the Time Scale in bars and
beats. Use this Time Scale if you are working
with musical material that must align with bars
and beats.
Minutes:Seconds Displays the Time Scale in
minutes and seconds. As you zoom in farther
with the Zoomer tool, the Time Scale begins to
display tenths, hundredths, and thousandths of
a second.
Time Code (Pro Tools HD and Pro Tools LE with
DV Toolkit 2 Only) Displays the Time Scale in
SMPTE frames. The Time Code Rate and Session
Start time are set from the Session Setup win-
dow.
Pro Tools supports the following frame rates:
23.976, 24, 25, 29.97 Non-Drop, 29.97 Drop,
30 Non-Drop, and 30 Drop frames per second.
Feet+Frames (Pro Tools HD and Pro Tools LE with
DV Toolkit 2 Only) Displays the Time Scale in
feet and frames for referencing audio-for-film
projects. The Feet+Frames time display is based
on the 35 millimeter film format.
Samples Displays the Time Scale in samples.
This format is very useful for high-precision
sample editing.
To ensure your tracks align with the bars
and beats in your session, record with a
click (see “Recording with a Click” on
page 271). Material that is recorded with-
out listening to the click can still be aligned
to bar and beat boundaries in Pro Tools
with the Identify Beat command (see “Iden-
tify Beat Command” on page 509), or with
Beat Detective (see Chapter 24, “Beat De-
tective”).
