Exporting OMFs from final cut and re-imoprting back as AIFF files, sync is not perfect!!?

Hello!

I need to deliver OMFs to my sound designer..in sync..

I exported OMFs which are around 1GB, from Final cut and imported them into Sountrack Pro in order to get an export (one single big file in AIFF) that I can bring into final cut to check that everything is on sync.

So I've done it and the sync is not perfect: I've taken a close look and I can't discern a pattern but when the clips are delayed it's by two or four frames. This isn't a drift issue as later clips will sync up fine.If I try to sync some segments of the whole clip, other segments get out of sync.

I export omfs without crossfades and 10 second handles. All my audio are AIFFs at 48KHZ.

Does anyone know how am I suppose to be exporting OMF and importing in soundtrack pro?
also, how do i export these OMFs back into final cut so i don't have a cync issue?
thanks!!!

OH REALLY? and how do you send OMFs to STP? trying to find it..
thanks Michael!

Thank you!
So before I was just doing export: audio to OMFs...

Following your suggestions:

I just tried, export: for soundtrack
but it doesn't let me check audio only, and there is no OMFs option

then I tried send to: Soundtrack Pro audio file project

This only happens when the audio files are selected in the timeline..otherwise i don't have the option. But then stp opens up and where are the OMFs? i just see the window with wav file and even the video...
