I have shot a conversation of two women sitting opposite. It was done with one camera and alternate shots. I used a Rode NTG3, but I know it would be better other mic like the Rode M3 or the AT 4053b. The studio set is big so it has a lot of reverb that I tried to damp with blankets. The problem/question is: the dialog lines must be very well separated in order to edit the sound OK and more if there is reverb, but in real acting sometimes it is necessary that both talents talk at the same time stepping one to the other in order to be more natural. Perhaps this would be easier with an omni mic, but the I would pick up more reverb. Perhaps a supercardioid like Rode M3 on top of both? Any advice about recording conversations like this one? You can see the result (it is an acting exercice) (Rode NTG3 and Fostex FR2LE) here:
Thank you.
