Using OMF and AAF Files
The OMF and AAF formats provide a way to consolidate all of the audio files and audio
edits from a third-party video or audio editing application into one portable package.
The picture editor can choose to include handles (extra footage beyond the In and Out
points of a clip that provides a safety margin in case you need it during the sound edit
and mix). Here are some things to keep in mind when using OMF and AAF files:
 OMF and AAF exports generally omit unused media to keep the overall file size low.
If you want to “steal” a performance from another take, you might be out of luck with
an OMF or AAF export.
 OMF or AAF exported files are usually truncated. If a music piece was edited into
many small clips during the picture edit, the OMF and AAF export process applies
those edits permanently on the file level. Sound editors usually prefer to have one
original piece of music with (nondestructive) edits referring to it.
 It is always a good idea to have single-frame “sync pops” at the top and tail of the
video and every single audio track to verify synchronization.
 OMF and AAF files do not include video, so usually, a video file needs to be
exported separately.
 To exchange OMF and AAF files with ProTools, you will need DigiTranslator, the
Digidesign interchange application, which is sold separately.
 Volume automation and panning automation is not always included in OMF and
AAF files.
 OMF and AAF exports often include audio files with very long and complicated
filenames.
 OMF and AAF exports support a single sample rate. All the audio files in a single
export must have the same sample rate.
 OMF packages (that contain media) are limited to a 2 GB maximum file size.
Exporting to AAF
You can export Soundtrack Pro multitrack projects as AAF files.
To export a project to an AAF file:
1 Choose File > Export AAF.
The Save dialog appears.
2 In the Save dialog, type a name for the file and browse to the location where you want
to save it, then click Save.
