When you see a scene, and it has two people in the scene only. When Person A is speaking, the shot is a medium shot of him and him only talking. Then it changes to a medium shot of Person B when they start talking. Is this done in 2 takes, i.e. Once Person A has stopped talking, action cuts, and camera is moved around to the other side to begin Filming Person B...Reason being, when you see Person A talk, you don't see an additional camera behind him, so obviously it isn't a continuous shot
