Hello Max and welcome to the Cow Audio Forum.
On any number of occasions, I have counseled producers with whom I’m working that X or Y won’t work and can’t be fixed in post.
You say wildly varying indoor environments. Like what? Perhaps you should consider choosing environments that are not so challenging. Why try to fly in the face of physics? Rethinking your location choices will improve the potential quality of your productions.
Shooting an interview with four people. A bad idea with one camera in any case. Panning, focusing and reframing is not likely to result in an attractive video timeline. What will work better will be to break the interviews up into “two shots”, where two people may be interviewed. That’s something that most cameras can handle. But even then, care has to be taken so the person not responding to a question isn’t just hung out to dry until it’s their turn.
The TASCAM DR-60D has four inputs; two balanced and two unbalanced. You could shoot an interview with four inputs and or tracks with four mics and then spend a lot of time in post ducking the tracks of everyone who isn’t talking at the moment.
I just had these choices to consider last week. EIght people, three cameras – master shot and two angled cameras. We used two people on booms each one feeding one camera and each one covering four of the eight people. In your case, you could use a stationary boom on one-person interviews and manually operated boom on 2, 3 and 4 people.
