lost channels in wav to aiff
Posting this in the FCP forum since my workflow may have something to do with it.
I’m working with Pro Res 422 footage (1920×1080) which has been synced up with wav files in FCP 7. While I understand some people say just to stick with wav, I would like to have some help understanding why converting to aiff changes my 4-chan wav files to 2-chan aiff files.
This is probably irrelevant, but sequence settings are 1920×1080 HDTVi, square aspect ratio, 23.98, ProRes 422, audio set to 48kHz 24-bit. (In the process, perhaps someone knows why the default “Would you like to match sequence settings with clip settings?” is HDTV 1080i?)
More immediately, here is my audio workflow:
Using Compressor 3.5.3, I converted .wav files (48 kHz 24-bit 4 channels) to the aiff preset (AIFF 48:24 stereo. I figured “stereo” was giving my problems, but I need help with which channel setting to use. When I pull the native wav files into FCP, there are 4 separate tracks. I tried converting to AIFF mono in hopes that I would get 4 separate mono tracks, but no. I have done both: dragging folder from Finder with the audio tracks inside, and dragging individual audio file from the Finder window. I have done those things both in my main timeline (whole film), as well as in a new project and sequence (same settings), having first closed and restarted FCP.
Perhaps the answer is to stick with wav. I edited this whole thing (feature film) with wav for all the audio recorded during principal photography. All subsequent audio and music are in aiff, as that was the recommendation I have gotten from these forums as well as my sound mixer – although he did not explicitly say not to use wav. I’m prepping for sound mix in a couple weeks. Hopefully I can get this out sooner rather than later. As is the case with everyone. 🙂
Any help would be appreciated – thanks.

Lisa,
If you would like an AIFF File, you can export from FCP.
Drop your 4 chans. of .wav audio onto an FCP sequence.
Go to Sequence settings, right hand tab is Audio settings.
Select 4 channels and then click to make them dual mono.
close sequence settings.
On you sequence, control click the on/off button on audio track 1, select Audio Outputs 1. Control click the on/off button on audio track 2, select Audio Outputs 2. and so on for 3 and 4.
Now that the outputs are properly assigned you can Export and choose “Export to AIFFs” This should give you 4 tracks of AIFF audio.Jim P.
