Chapter 17: Importing and Exporting Session Data 383
Enforce Avid Compatibility
If the Enforce Avid Compatibility option is enabled,
all AAF and OMF files and sequences will meet
the specific requirements of Avid Video worksta-
tions. Sample rates are limited to 44.1 kHz or
48 kHz. Exported clips will be padded to the near-
est frame boundaries (Quantize Edits to Frame
Boundaries). This padding ensures that the place-
ment of a file in the Timeline will be the same on
sample-accurate as well as frame-accurate sys-
tems.
Target Project Timecode Format
Select the timecode format for the project into
which this file or sequence will be imported. This
may be different from the timecode format of the
current session. This parameter allows clips to be
placed correctly in sessions with different time-
code formats, and also calculates how many sam-
ples must be added to pad clips to frame boundar-
ies.
Quantize Edits to Frame Boundaries
Pro Tools allows sample-accurate placement of
clips. In Pro Tools, you can place a clip of any
length at any position, without any requirement for
aligning clips with frame boundaries.
However, most video editing programs, such as
Media Composer, only support frame-accurate ed-
iting. In these programs, you can only edit sounds
on whole frame boundaries, limiting your preci-
sion.
Selecting
Enforce Avid Compatibility will
automatically select
Quantize Edits to Frame
Boundaries
.
The
Quantize Edits to Frame Boundaries option al-
lows Pro Tools to export your sample-accurate
Pro Tools edits into an AAF or OMF file so they
appear as frame-accurate.
When you quantize edits to frame boundaries, you
must enter a handle size (length) under Audio Me-
dia Options. See “Consolidate Handle Size (Milli-
seconds)” on page 386.
A master clip consisting of the clip plus the handle
size (length) on both front and back will be ex-
ported. The exported sequence creates a subclip
which is equivalent to the original clip, but ex-
tended to the farthest frame boundaries. For exam-
When exporting a sequence with multi-chan-
nel audio tracks, the Enforce Avid Compati-
bility option must be enabled.
The Quantize Edits to Frame Boundaries set-
ting must be selected when you are
translating your Pro Tools session for use in
frame-accurate editing workstations. There-
fore, it is automatically selected
whenever you export tracks with Enforce
Avid Compatibility selected.
