Exporting OMF files from FCP (Needs to be sent out Today)

We are about to send our first feature off to a post facility. We did our editing on FCP and the post facility wants our audio files in OMF format. Our problem is that our audio files are well in excess of the 2G max. What is our best course of action.

Also our quicktime movie is running at about 35Gigs.
 
You'll have to break up the OMF into several exports split by track. How many exports will depend on how long your movie is how long the handles are. You'll have to experiment on what works within the 2 GB limit, but usually the first four tracks have most of the production audio and so will be larger in size that other tracks.
 
Well, we have a 95min runtime with stereo pairs (recorded at 96kHz/24Bit) across 20 tracks. Is it best to stay at the 96kHz or should I drop to the 48?
If I drop to the 48 was it pointless for us to even record at the 96?

Um, yes it was pretty pointless. Of course that is my opinion, but I don't see anybody recording production at 96 and I can't think of a good reason to do so. FX are more and more recorded at 96 but that is mostly because FX are often manipulated and slowed down for design purposes. What's your final format? Your going to have to down sample at some point. Ask your audio post folks what they want. I would probably have you drop it to 48/24, or I might end up doing it my self. I doubt that I would end up staying at 96 but that also would have a bit to do with what I was editing in and if there was some odd reason to stay in 96. If I was staying in 96 I would only leave the production tracks at 96 and do the FX work in a separate session at 48. There is only a possibility of some advantage of 96 IF the audio was recorded at 96 in the first place and has stayed at 96 the whole time. I know that sounds obvious but you would be surprised by the number of people who want to up-sample to 96 or make their stereo track "surround" because it's "better".

Second sound post does not need that big a video file. Definitely check with them to see what they want but as a rule audio post wants small and easy to copy and play back. That has been MJPEG-A, is mostly DV these days or h.264 with a key frame on every frame.

Instead of splitting the film up in the traditional reels you might just limit the number of tracks you output but do the whole length. It can be a pain to join the reels if you break up the film and are not familiar with that way of working.
 
Ditto to what Noiz said ^^^

96 for production sound is a waste of space. 24/96 over 90 minutes, your tracks will be HUGGGEE. Thank your lucky stars you aren't doing stems ;)

Cheers
