I just got a Canon C100 and I am using only one lavalier mic for all interviews so I have one channel of nice mic audio, and one channel of on board mic audio that I will eventually get rid of. When I log and transfer the footage into FCP7 there is no option under import settings to split the two channels of audio into dual mono channels. The footage I end up with in my browser is linked stereo pairs and I can't figure out a way to modify the master clip- only a way to unlink the audio once it is in the timeline, which will be a big pain to do individually. Is there a way to modify the master clip audio in the browser?
So apparently AVCHD automatically mixes down on L&T no matter what, so I am thinking the best thing to do will be to edit away and once I have my timeline set, kill all the audio on track one for the whole timeline (track one is the onboard mic) and then change the pan of track two (the good mic) to 0. Any reason this isn't the optimal solution?
