Continuity editing helps ensure a consistent and smooth flow between shots through various techniques. Shot reverse shot shows two characters facing each other to indicate conversation. Establishing shots introduce new scenes by showing the location. The 180-degree rule dictates that the camera stay on the same side of an imaginary line between characters during a conversation. Matching on action cuts between shots to depict the same action in more or less detail. Eye line matching cuts from a character's gaze to what they are looking at. Cross-cutting edits between two simultaneous actions in different locations. Montage editing uses frequent cuts, dissolves and jumps to convey messages through compressed sequences of shots.
