Session Start Offsets
With Pro Tools 6 and higher, you can offset the
display of incoming time code in the Pro Tools
application. This is useful when you want to ad-
just the display of time code to match the start
time of the session (such as with source material
that starts at a different time), or compensate for
source material that is consistently offset by a
fixed number of frames (such as with some
color–corrected video masters).
Pro Tools provides three different types of Ses-
sion Start Time Code Offset settings. These off-
sets include:
• MMC (MIDI Machine Control)
• 9-Pin (Serial machine control)
• Synchronization peripherals such as the
SYNC I/O, USD, or other peripherals (for ex-
ample, MIDI interfaces that provide MIDI
Time Code).
Unique values can be defined for each of these
three types offsets, or you can link all three to
adjust in unison.
Positive and negative offset values can be en-
tered to offset Pro Tools time code display later
or earlier, respectively.
Offsets and Time Code Displays
The SYNC I/O (or USD) Time Code Display con-
tinues to display actual incoming time code, re-
gardless of any Session Start Offset applied in
Pro Tools.
To apply an offset to the session start time:
■ In the Session Setup window, enter a new Ses-
sion Start time in an offset field.
To apply the same session start time to all
devices:
■ In the Session Setup window, select Link to
apply the same offset value to all devices.
Time Code Settings
The Time Code settings control time code gen-
eration, Freewheel, and session Pull Up and Pull
Down options.
Configure these settings as appropriate for the
current project and situation. (For complete in-
structions, refer to the Pro Tools Reference Guide
and the SYNC I/O Guide.)
Time Code Reader Offset
The Time Code Reader Offset lets you set a “trig-
ger offset” for incoming MIDI Time Code, in
samples. (In previous versions of Pro Tools, this
feature was called Sync Offset.) You can use Time
Code Reader Offset to compensate for the la-
tency of a MIDI sound module or other MIDI de-
vice chain.
