The Rules of Continuity in editing

- Shot Reverse Shot - 

This is a film technique which is applied during scenes where there are several characters, this is usually where dialogue is shown between two characters. This links to the 180 degree rule, as this characters looking back and forth at each other.

- Match-on-Action - 

This refers to when one shot cuts to another that depicts the result, or continuation of an action that was shown in the previous shot. This "matches" the action. Match on action creates a continuous feel of time to the shots, as the shot cuts do not tend to be noticeable.

- The 180°Rule -

This is considered an essential to filmmaking and continuity editing. When done wrong, it will affect the overall outlook on the scene, but in some cases, may be an effect the director intended. The purpose of this rule is that the camera should stay on the same side throughout every shot of the scene. When the camera moves across the other side, it is identified as "crossing the line"....
