Chapter 24: Time Code Synchronization 359
Information in these fields is displayed in
SMPTE Time Code, Minutes:Seconds,
Feet.Frames, Samples, or Bars & Beats, de-
pending on which Time Scale format is se-
lected.
A highlighted numeric field indicates the
current active field for numeric entry edit-
ing. Entering a value in a field allows you to
move a selected parameter to the time loca-
tion that you enter. The Start, Sync Point
and End fields are accessible when the
Grabber is active. Only the Start or End (de-
pending on where you click the mouse)
and Duration fields are active when the
Trimmer is active (see “Using the Trimmer
in Spot Mode” on page 360).
✽ To increase or decrease SMPTE values in
the Spot dialog by a specific number of
frames, press “+” or “–” on your numeric key-
pad, enter a number, and press the Enter key.
Subframes
A subframe is 1/100th of a frame. The Use
Subframes option enables you to use these
smaller units for greater accuracy. This
command adds an additional time field in
the SMPTE hours:minutes:seconds:frames
box, which appears as the far right time
field when enabled. Use a period to sepa-
rate subframe values from whole frames.
✽ Subframe measurements are not available
in the Current Time Code field.
Capturing Time Code
Pro Tools also allows you to easily “cap-
ture” frame locations on the fly in this dia-
log by pressing the “=” key, or by clicking
the Current Time code button while valid
time code is being received by Pro Tools.
With VITC, you can accurately capture a
paused or “crawling” VTR’s SMPTE loca-
tion.
When SMPTE Time Code is selected for the
Time Scale, pressing “=” captures the in-
coming time code. When Bars & Beat is se-
lected for the Time Scale, pressing the “=”
key will capture to the nearest measure.
Although the Capture Time Code button
works with free-running Linear Time Code
(LTC) or VITC, frame numbers of a paused
frame can only be captured with VITC.
The USD is the only current Digidesign
hardware that can read VITC. Also, you can
use the optional MachineControl software
to read the current time code address over
9-pin or V-LAN.
