Chapter 24: Time Code Synchronization 361
Start or End and Duration fields to specify
exactly where you wish to trim the region’s
beginning or end. Use this to edit the
length of a region to correspond to a partic-
ular visual “hit point.”
Trimming a region which contains a Sync
Point (see “Identifying a Sync Point” on
page 362) will not affect the SMPTE loca-
tion of the Sync Point, unless the region is
trimmed past the Sync Point.
Time Stamping
Pro Tools time stamps every region re-
corded online with the original SMPTE
time at which audio was recorded. You can
recall this original SMPTE time for a region
by clicking the Original Time Stamp button
in the Spot dialog.
You can also spot a region to a separate
user-defined SMPTE time stamp, defined
using the Time Stamp Selected command.
Once the region is time stamped using this
command, you can click the User Time
Stamp button to re-spot a region to its user-
defined SMPTE location.
The Use Subframes option in the Spot dia-
log enables you to work with subframe ac-
curacy by adding an additional time field
in the SMPTE hours:minutes:sec-
onds:frames box. This additional time field
appears as the far right time field when en-
abled, and allows you to enter subframe
values in SMPTE dialogs. Use a period to
separate subframe values from whole
frames.
Show Original Time Code in
Regions
This command displays the original “time
stamped” SMPTE times in all regions cur-
rently placed in tracks. This SMPTE frame
number represents the time at which the
region was originally recorded online with
Pro Tools, and does not necessarily reflect
the region’s current SMPTE location in a
track.
To display the original time stamps in regions:
1 Choose Display > Display Time in Re-
gions > Original Time Stamp.
2 To hide Original Time Stamps, choose
Display > Display Time in Regions > None.
Time Stamp Selected
If you wish to create a separate user-defined
SMPTE time stamp, you can use the Time
Stamp Selected command in the Regions
List pop-up menu. This command allows
you to select a region (or regions) and rede-
fine its SMPTE time stamp. The original
time stamp and the user-defined time
stamp are then stored with your session.
When audio is first recorded, the user-de-
fined time stamp will match the original
time stamp, but you can change the user-
defined time stamp at any time using the
Time Stamp Selected command. This fea-
ture is particularly useful in post-produc-
tion situations where the SMPTE time code
on video “work prints” often changes from
one edit revision to another.
