Audio Issues after exporting Multicam project using Compressor

I am experiencing an odd issue when I export my project to Compressor ONLY when I have a Multicam clip. I will explain the issue and then the settings.

Issue: After exporting the project using Compressor, one of the audio tracks during my Multicam clip just won't be there. Everything else is perfect. For example, I have a 3 camera Multicam clip, where I am using audio from 2 out of the 3 cameras. When I am on the "Camera B" video, the audio works, but when I switch to "Camera C", the video works, but the audio is not there. To be clear, I can hear the audio just fine within FCPX, it just doesn't export using Compressor.

Here are my project settings;

Video: 4K

3840x2160 23.98p

Rendering: Apple ProRes 422 HQ

Standard - Rec.709

Audio: Surround 48kHz

Compressor settings:

Preset: 4K

Video: H.264, 3840x2160, Progressive, 23.976 fps Rec.709

Audio: MPEG-4 AAC, 5.1 (C L R Ls Rs LFE), 44.100 kHz

All of this is running on a MacStudio with an M1 Max and 64GB of RAM. I am also experiencing the spinning beach ball in my timeline ONLY when trying to play over the Multicam portion of my project. (I doubt that this is related to the audio issue though.)

Has anyone else had this issue? Does anyone know how I can export and include all channels of my Multicam audio?

Mac Studio, macOS 14.4

I have exported directly from FCP to Compressor with a variety of presets, and every one I have tried has the same audio issue. It is almost as if Final Cut isn't exporting 1 of the audio tracks properly, but for the life of me, I can't figure out what I am missing.

I don’t mean the Send to Compressor function, which is what I think you mean. Correct me if you mean something else. I meant to use a Compressor preset inside the FCP export function bypassing Compressor. Does the audio export directly from FCP using the export function without going to Compressor?

Yes. Compressor doesn't pull in all the audio from my Multicam portion of the project, where the built in compressor to FCP doesn't have any issues with the audio from the Multicam portion of the project.

Ok, sorry for the delay getting back to you. I was able to add a destination into FCP from a Compressor preset. That did export the audio just fine, but that still doesn't resolve the issue with Compressor. I did find out that this doesn't only happen on a Multicam clip, but any compound clip with multiple sources of audio. Any idea on what is causing Compressor to not export the audio properly?

FWIW, I was never a fan of using “Send to Compressor”… for a single export, I just use Compressor Settings right within FCP, as Tom mentioned.

And if you want multiple export formats it may be faster to make a ProRes master in FCP and use that. Compressor cannot take advantage of parallel jobs when dealing with a FCP project, but can when working with a video file.

Try using your Compressor preset when exporting from FCP directly. Does that work?

That will work, but for this specific timeline, I had some footage that was HDR and the compressor app handled that better than the built in compressor.

Are you saying that a Compressor setting added to FCP works differently and produces a different result from the same setting in Compressor?

Have you tried to use the function that lets you add a Compressor string to FCP? It’s available in Destination settings. Does that work?

I will try that and get back to you. Thank you for helping me out with this. I appreciate your efforts here, even though we haven't gotten to a concrete solution just yet.
