Chapter 35: Working with Synchronization 555
Time Code Settings
The Time Code Settings section provides gener-
ator, freewheel, and pull up/down options.
These controls are located in the Time Code Set-
tings section of the Session Setup window. Click
the Time Code Settings expand/collapse icon to
show or hide these controls.
Generator
The Generator lets you enable Pro Tools genera-
tion and output of LTC and MTC using the
SYNC I/O. For more information, see “Generat-
ing Time Code” on page 563.
Using Synch This option outputs time code from
the Device type selected in the Synchronization
page of the Peripherals dialog.
MTC to Port When enabled, outputs MIDI Time
Code to the MIDI destination selected in the
pop-up menu. In Pro Tools on Windows,
choices appear as they are in your windows con-
figuration (for example, Port 1, Port 2, and so
on). In Pro Tools 6.x on Macintosh, choices are
based on your AMS profile (Audio MIDI Setup).
Freewheel
The choices in the Freewheel section let you
configure how Pro Tools will freewheel, or con-
tinue playback if time code is interrupted or cor-
rupted. Use these options to protect against er-
rors that can occur if your SMPTE time code
source has “drop outs” or temporary lost signals.
None No freewheel is applied.
Frames Sets a number of frames to freewheel,
from 1 to 120 frames. This value defaults to 8
frames, which is the recommended setting for
most applications.
Jam Sync Lets Pro Tools trigger synchronization
to incoming time code, and continue to play
back even if time code input is completely inter-
rupted. It can be useful if time code is damaged,
or has been accidentally erased from your source
tape.
Pull Up/Down
When Pro Tools is used in conjunction with a
SYNC I/O, or a third party peripheral or syn-
chronizer that supports pulled sample rates, this
option allows you to “pull up” or “pull down”
the current sample rate.
For general information, see “Working with
Film-Originated Material” on page 544. For
more information on applying pull factors in
Pro Tools, see “Pull Up and Pull Down” on
page 558.
Remember, pull up and pull down are ap-
plied differently in different workflows.
Make sure you check each project’s specific
workflow before you begin your work.
