Continuity editing is a technique used in an attempt to create a rational space. This can be achieved by using a range of techniques. Here are a few of those techniques: point-of-view shot (POV), axis of action line, eye line match, directional continuity, and the match on action cut.
An example of a POV would be if you were screaming in agony, swinging your head from side to side. The director would take a camera to show the way you felt, he would take the camera and move quickly to and fro to emphasise your movement. This would make the audience feel the pain and suffering you feel because the swinging would represent you agony and hurt.
