Definitions

Match on Action - A continuity cut which unites two different views of the same action together at the same moment in the movement, making it seems to continue uninterrupted; for example, when a character claps his hands and the film cuts to a close up of his hands as they come together.
Shot/Reverse Shot - The alternating of two shots to establish an interaction between the objects in each shot; for example, when a character in shot A is speaking and shot B reveals the character to whom he is speaking.


180 Rule - The continuity approach to editing dictates that the camera should stay on the one side of the action to ensure consistent left-right spatial relations between objects when the shots are edited together. The 180 degree line is the same as the axis of action.
