Mike Thorton has an extensive article AAF and OMFs – Post Audio Export Panel On the Good, the Bad and The Ugly. It goes pretty into depth, and I know there have been a lot of issues with AAF’s in the past, but I think most of them have to do with the whole Premiere Pro and linked clips completely breaking AAF export.
The project I have been working on of late has 16 bit 48 hz audio for the most part, but our VO guy gives us amazing 24 bit audio, but because of this the OMF’s that Premiere Pro kicks out do not sync up when the audio guy gets them. Some tracks go out of sync, and not others. And this keeps happening.
And there is a workaround. You need to use the Edit in Adobe Audition: Sequence command and then use Audition to export the OMF correctly.
This is a feature that needs to be pulled out of audition and put into Premiere pro, working OMF export, otherwise why have the feature there at all?
Come on Adobe. And I see they have had this issue for a long time from posts online! FIX THIS!
EDIT:
I have been told that basically Adobe has given up on OMF and now focuses on AAF, so next time I will see if the mixer can take AAF.
