Yeah. The recorder works well when I do straight voiceovers. When I mix voieover and on-camera stuff, the audio doesn't seem to match (because they're recorded at different times and under different conditions, I suppose). I try to set the volumes so they're about equal, but I don't know what else to do about it.

This is the external mic I got: https://www.amazon.com/gp/product/B01N35BKCS/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

I only used it a couple of times, but it seems to pick up too much ambient noise and doesn't pick up my voice loud enough.
