Thanks for your help guys.
PI want to be sure that this would be the best way to do it. My client doesn't want to experiment. Purchasing things and not being able to return them would really be a bummer if it didn't work.
She wouldn't be recording sound on her iphone. Honestly all of my other clients were fine with just using the iphone to record their videos, so this is new to me as well. I'm pretty happy that she wants to have her videos sound more professional, but we are both new in this respect and somehow I got the job of trying to figure it out.
So, to be perfectly honest, anything beyond recording on the phone or a video camera is a totally foreign subject to me. I really need some step by step or where to find the info.
I'll look into the products mentioned and see if I can make sense of it.
Thanks again
