Redefining a Time Code Position
(Pro Tools HD and Pro Tools LE with Complete
Production Toolkit or DV Toolkit 2 Only)
Use the Current Time Code Position command to
redefine the current time code position and ses-
sion start time. By creating an insertion point
(or selection), and then entering the new time
code position for that location, the session start
time will be recalculated based on the new, rela-
tive Time Code location.
To redefine a current Time Code code position:
1 With the Selector tool, click in a track (or
make a selection) where you want to redefine
the position.
2 Choose Setup > Current Time Code Position.
3 Enter a new SMPTE frame number in the dia-
log to correspond to the time code shown in the
dialog.
4 Click OK.
Displaying Time in SMPTE Frames
(Pro Tools HD and Pro Tools LE with Complete
Production Toolkit or DV Toolkit 2 Only)
In Pro Tools, you can set the Main Time Scale to
Time Code (SMPTE) and this will be displayed in
the Main Counter. Though Pro Tools will still
synchronize to incoming SMPTE time code if
the Time Scale is displayed in Bars|Beats, Min-
utes: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,
do one of the following:
„ Choose View > Rulers > Time Code.
– or –
„ Click the Main Counter selector in the Edit
window and select Time Code.
Pro Tools displays time code values in the cur-
rently selected SMPTE frame rate.
Sub Counter and Sub Time Scale
Display
You can display a Sub Time Scale in the Sub
Counter. For example, 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, click the Sub
Counter selector and select Min:Secs as the Sub
Time Scale.
Pull Up and Pull Down
Pro Tools supports up to 4% pull up and pull
down, with support for an additional 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 Table 48 on page 1020.
While a Digidesign SYNC peripheral is not re-
quired in order to use the extended pull up and
down options provided in Pro Tools, a SYNC pe-
ripheral is the only device that can be controlled
If your insertion or selection is not on a grid
boundary, it will round to the closest
boundary.
