I've noticed some weird audio level behaviour with multi cams. If I configure the audio of the clips to be dual mono in the angle viewer, then when I add a limiter to the clips in the project, the audio is approximately -6dB lower than expected. For example, if I set the limiter to 0dB, the actual limit is set to -6dB. If I see the limit to -3dB, the actual levels turn out to be -9dB.
And here is the kicker. If I go back into the angle viewer and set the clip audio to be stereo, the limits applied through either the limiter filter or the compressor filter (which is applied to the clips in the project timeline) are fine.
I'm running 10.1.3, and haven't tried any other versions. I'm very hesitate to call this a bug, rather I thinking I must be missing something here.
