Preliminary exercise: Continuity task involving filming and editing a character opening a door, crossing a room and sitting down in a chair opposite another character, with whom she/he then exchanges a couple of lines of dialogue. This task should demonstrate match on action, shot/reverse shot and the 180-degree rule.
Continuity - Everything seems logical on screen and it flows. If this is broken then you become aware that it is artificial.
match on action -Cutting the shot as an action is about to happen, and then continuing the action in another shot as it finishes. For example, opening a door and going through it.
shot/reverse shot - camera positions and editing to cut conversation between two characters. Switching back and forth between two shots.
180-degree rule - In a shot with two people facing each other having a conversation, the camera must shoot on one side of the "line" between them, rather than just shooting two scenes facing each character so it looks like they're talking to themselves rather than each other.
