Yeah I was thinking of doing more rehearsal time next time, in order for the performances to be better when working fast during shooting, if that's better.

Well, what I could do is not follow any coverage formulas at all, and just shoot the shots I want only, with no back up coverage. However, is this a good idea, if I am still amateur at filmmaking?

It depends if you're a highly skilled amateur or just learning.

Well I could try it and see how it goes.
