I want to make sure Ill be okay for sound. I have 2 Zoom H1's with lav mics attached. Ill be shooting with a GH2, Hero3 Black addition and a Canon Vixia. I was going to mic the groom low on his jacket and boost the gain. I head this is a good trick. Should I mic the JP? Should I have an additional mic on the GH2 even though they have mics? I just want to make sure I dont need anything...or do i? Thanks for the insight!!
