PROJECT FILE INTERCHANGE

Export audio data as Sound Designer II/AIFF/
WAV E fi l e s
These options apply to audio being copied during
the export operation, if any. Choose the desired file
format for the audio files being copied to the AAF
or OMF project.
The Sound Designer II file option is disabled (not
available) when you are exporting to an AAF file
because AAF files do not support Sound
Designer II files. In general, exporting as WAVE or
AIFF is recommended.
‘Export fades as’ options
The Export fades as OMF/AAF effects option
produces fades and crossfades that can be fully
modified in the target application after the transfer,
if desired. The Export fades as precomputed regions
option renders each fade as an audio region,
preserving the exact nature of the fade or crossfade
as it was programmed in Digital Performer but
rendering it un-modifiable. For example, if you like
the way your fades and crossfades sound already in
Digital Performer, and do not need to further
modify them in the target application, use this
option.
If you’ve chosen the Quantize edits to frame
boundaries option, then the Export fades as OMF/
AAF effects option is not available (grayed out).
Exporting 24-bit audio
The Convert 24 bit audio to 16 bits option converts
all 24-bit audio in the project to 16-bit audio. Most
third-party audio applications support 24-bit
audio, so it is recommended that you enable this
option only if you must. If you are exporting 24-bit
audio and wish to maintain this bit depth, choose
Export 24 bit audio directly.
☛ One notable 16-bit–only example is
OMFTool/DigiTranslator 1.0. If you intend to open
the OMF file in DigiTranslator 1.0, enable the
Convert 24 bit audio to 16 bits option.
Export sample-accurate edits/Quantize edits to
frame boundaries
For Avid Xpress and other applications that require
OMF/AAF files to specify all timing in SMPTE
time code frames, choose Quantize edits to frame
boundaries. Digital Performer’s current frame rate
setting (Setup menu> Frame Rate) is used. This
frame rate setting must match the frame rate in the
Avid Xpress session into which you will import the
OMF/AAF file.
Also, when using the Quantize edits to frame
boundaries option, you are forced to use the
Consolidate audio files and Export fades as
precomputed regions options. All of your
soundbites will get trimmed so that they start and
end on frame boundaries. To maintain timing and
ensure that all audio is properly included, Digital
Performer then generates one-frame audio regions
placed before and after the trimmed soundbite,
containing the audio that was trimmed.
For all other applications (that don’t require frame-
based timing), choose Export sample-accurate
edits. Consult the documentation for your editing
application to determine if it requires frame-based
timing for audio.
Export clip-based volume/pan
Because the OMF and AAF interchange formats
support a clip-based automation model,
automation data between clips is lost when
exporting, but automation data within the
boundaries of every audio region is preserved
during transfers.
The Export clip-based volume and Export clip-based
pan options determine whether volume and/or pan
automation data will be included in the resulting
OMF or AAF interchange document.
