So I just finished editing my first short film and when I finally burned it to DVD, many of the audio tracks were muffled. I was told this was because some of my audio tracks were mono and that to fix this I needed to copy every mono track and paste it with the 'pan' dragged over to the other side, for full stereo effect, one copy on the left and the other copy on the right. This makes sense but I'm wondering if I literally have to do it for EVERY audio track in my project. My sound guy recorded to two tracks, one for the lavelier and one for the boom, and then mixed it together as we recorded. Does that mean I have to break apart this mix and give stereo tracks for both mic recordings? A right and a left for the lav, and the same for the boom? This seems a little laborious and I'm wondering why you couldn't just record to stero for each mic in the first place..
