I had a problem with a 45 minute sequence which was multicam
getting it into an .omf for pro tools. It would export just fine
but most of the audio was missing in pro tools once imported.
I’m running the MAC version of CS 6
To get around this:
Make sure audition is updated to latest version.
from premiere “send it” to audition.
once thats done, hopefully without errors, export an .omf from audition.
That’s what solved it for me. Pro Tools then imported everything properly.
