Exporting 5.1 stems as OMF/AAF, region/file names change

Hi all!

I'm having a ball trying to export 5.1 stems to OMF/AAF. Logic chooses to remove the -L and -R suffixes from the files. Importing to ProTools is then totally meaningless as I will have to rename the files (there's a LOT of them) to enable ProTools to treat the files as 5.1. Another thing is that the OMF file crashes ProTools when opening but I also tried with the AAF export and then this renaming thing became a problem. Any ideas? I have seen the Logic has skipped this suffixes befor but now it really is a problem. Seems like I have to spot all the files into ProTools manually. Nice, really nice.

Ginge70,

I'm having problems with 5.1 too, so I don't know that I can help. If you are exporting maybe you should try bouncing instead with PCM selected and Surround bounce on.

Hi and thanks for the reply!!

The song I'm trying to export to omf/aaf is a song where I've collected all the score instances in the movie. The way I work is like this: I compose the music for a specific scene in the movie, then I bounce it to 5.1 and place it in a new song. This new sog will then after a while contain the total score of the movie, each song represented by 6 monofiles panned out, since Logic isn't able to treat groups of 6 files like one surround-file as you would in ProTools. This collection of files is what I'm trying to export so I won't have to spot each and every batch og 6 monofiles into ProTools manually.

Best Regards,

Ginge

hi mate,

there should be no problem exporting AAF to PT with logic. i do it all the time. it will always do it as split stereo or mono. i am not sure why logic would be removing -L -R from the files - that doesn't sound right. mono files should be a cinch.

the name of the files are being preserved right?

exporting them into PT should result them being placed exactly as you saw them in logic, same order - everything.

not sure this helps you much - only to perhaps check pilot error is not involved. here is a case were it might affect the import:

i found AAF to fail if the first audio file is before the TC for bar 1. if it is exported to the AAF, PT will spit it back at you.

Hi there!

The names are being preserved as far as the -L and -R suffixes. Ls, Rs and LFE are not altered. Exporting stereo files is no problem and a workaround could be bouncing left and right as stereo, but that is not possible when doing surroundbounces in Logic. I have changed the default Logic suffixes in order not to confuse ProTools which needs this naming to be able to treat a batch of 6 monofiles as one surround file. Possibly this wouldn't be an issue if I'd left the names alone, but I still think I should be able to choose the name of the files myself.

I have seen this unwanted renaming before, but only in region names where suffixes have been omitted. So the problem is not the omf or aaf export itself but Logic's automatic renaming.

I really wish Apple would implement a proper 5.1 handlig in Logic 8. The way it is now is really not worthy.

Spent the day spotting each 5.1 group of files into ProTools manually together with the sounddesigner. Not exactly efficient but at least I got to socialize 8-)

Thanks for the input!
