Suppose you have person A in one room, placing a phone call to person B in another room. How would you show the resulting phone conversation?
I can think of two ways: One is to split the screen, so person A is shown on the left side, and person B on the right side.
The other way, is to have alternating "full shots" switching back and forth between persons A and B.
What are these video techniques called? Are there other techniques that I've overlooked?
