You highlight “Finding/making a Y-adapter to allow plugging BOTH mics into the TRS stereo mic input on the DSLR.” as a potential challenge. But I thought you would just need a very simple splitter?
I suppose there is still the issue of how to monitor the microphones audio when recording? But then instead of something like the Rhode video mic pro, I could get a microphone with a headphone e.g. Shure Lenshopper .
Would this be a crazy idea to have two Rhode videomic pro mounted on the camera (one pointed front and one pointed rear) Is there any reason not to do this? Or am I better with the Rhode videomic pro for the front and a lav for the rear?
So are you saying a shotgun on the front and lav for rear is the way to go? What about decent bi directional microphones which have a narrow pickup on the front and rear (but nothing from the side) Do these exist?
