I am teaching my students how to do LCR (3.0) through quicktime mov and when I ran a test in a teaching venue, we got all our discrete channels correct but when we disabled our centre channel which has dialogue, sound effects and foley on it, you can hear that all of these sounds coming through the left and right which has the ambiance and music. The sounds are a lot lower than when they come through the centre but it is still a problem.
When the LCR was delivered to the editor, they assigned all the channels to their correct discrete channels and the left and right was panned off and the centre channel pan was in the centre. We ran the test a few times changed the distribution of the tracks from LCR to LRC etc but we still had centre channel bleed into left and right.
It could be our system but before I start to take apart our system I just want to know if anyone has had this problem before?
Thank you
