Having an irritating problem with Compressor 3.0.5.
I received my 5.1 mix as 6 uncompressed discrete WAVs from my sound designer/mixer. (L, R, C, LFE, Ls, Rs). I brought those into Final Cut Pro, set the timeline to discrete tracks and mapped each audio out put to tracks 1 thru 6, and synced them to picture. All good. Then I exported pictures as well as "File > Audio as AIFF > Grouped Channels" to get six discrete AIFFs. Checked them in QuickTime Player and each track contains what it should.
I did this so I could remove the 2-pop on each of the tracks and give them the same 5 second header as the picture export so everything will line-up in DVD Studio Pro later.
I rename each of the six track to end with (-L, -R, -C, -LFE, -Ls, or -Rs) and drag them into the batch window in Compressor. This part works fine as a new surround sound group is created and the tracks automatically map to the correct channel, as seen above.
I then drag the target preset for Dolby Digital Professional 5.1 onto the group and go through and uncheck all the stuff I want unchecked, set compression to "none" and the normalization to -31db.
Then I hit submit.
When I made the first DVD and tested it on my home theater, the center channel, surrounds and subwoofer were dead quiet, while the left and right front speakers were playing fine. So to check, I imported the AC3 into Final Cut Pro to look at the waveform. And this is what I saw... the first two tracks (L, R) had sound, the rest were stripped to nothing. And by the looks of it, comparing tracks 1 & 2 to the original on the left, it looks like Compressor did a stereo mixdown. It sounded this way in my home theater as well, dialogue wasn't missing or weak so that center channel info seems to have been mixed into the front left and right channels. Again, the source files mapped into Compressor do not sound this way. They sound right.
Please tell me someone has run into this and resolved the issue. Help?
