2 mono/1 stereo and prores????
OK, so I used to capture in HDV and then just have my sequence setting compressor set as Prores 422, not realising the stupidity of this…. anyway, I now capture directly to prores and I have a question about audio which is, why when capturing to HDV are the left and right channels of audio captured as two separate mono streams (2mono) whilst with prores capturing it captures them as stereo?
Why is stereo better than dual mono? (I mean as long as its coming out of both speakers???)
And also, when one is in a situation with crap sound from one channel and good in another, if that person were to ‘un’ stereo the pair, delete the crap track and duplicate the good one, am I right in saying that would basically result in dual mono again? (Because you’ve technically ‘deleted’ half the audio?)
Cheers!😀

I’m not sure why you get dual mono one way and stereo the other. Maybe it’s an option in the capture settings. Your approach to unlinking the audio, deleting the bad track, duping the good and re-linking is perfectly fine.

In my current project I’m shooting on a Red (so 4 channels audio, nothing explicitly L or R channel) and recording mono audio to two channels (as backup). I then rendered to HD in 422HQ.
The audio still came out as two channels of monaural sound, which it was; not stereo. My rendering program (RedCineX) doesn’t appear to have any choices about how it exports those audio channels.
The benefit to stereo, though, is that changes to levels that you make to a clip would affect BOTH channels at the same time (though panning doesn’t seem to work, or doesn’t work the same way as it does on a mono clip).

I’m not familiar with the Red’s audio workflow, but once tracks are in the timeline, you can easily switch from stereo to dual mono or vice versa by selecting the tracks and hitting Opt-L.

Right. I was just responding to the initial question about getting stereo out of one transcode and two monaural tracks from another.
