Displaying Time in SMPTE Frames
(TDM Systems and Pro Tools LE Systems with
DV Toolkit Only)
In Pro Tools, you can set the Main Time Scale in-
dicator to Time Code (SMPTE). Though
Pro Tools will still synchronize to incoming
SMPTE time code if the Time Scale is displayed
in Bars:Beats, Minutes:Seconds, or Feet.Frames,
it is usually more useful to use SMPTE time code
as your reference.
To set the Main Time Scale to SMPTE Time Code:
■ Choose Display > Time Code.
– or –
■ Click the Main Time Scale selector in the Edit
window, and select Time Code.
Pro Tools will display time code values in the
currently selected SMPTE frame rate.
Sub Time Scale Display
You can also display a Sub Time Scale. For exam-
ple, if the Main Time Scale is set to Time Code,
and you want to compare SMPTE time to “wall
clock,” when you are using 29.97 Non-Drop
frame rate, you can select Min:Secs as the Sub
Time Scale.
Pull Up and Pull Down
Pro Tools 5.3.1 and higher supports up to 4%
pull up and pull down, with support for an ad-
ditional 0.1% up or down. Separate rates can be
set for session audio and video (when video has
been imported or captured into the session).
When referring to 4% pull up and pull down,
the precise percentages used in pull ups is
4.167%. See “Audio Rates and Pull Up/Down
Options” on page 561.
While the SYNC I/O is not required in order to
use the extended pull up and down options pro-
vided in Pro Tools, the SYNC I/O is the only de-
vice that can be controlled from within
Pro Tools, and that recalls and restores pull fac-
tors automatically when a session opens. Other
synchronization peripherals must be configured
manually.
Selecting a Time Scale format
Pull up and down settings do not affect time
code generated by the SYNC I/O.
