Research definition of continuity editing

The 180° rule is a basic guideline in film making that states that two characters (or other elements) in the same scene should always have the same left/right relationship to each other. If the camera passes over the imaginary axis connecting the two subjects, it is called crossing the line. 


Match on action technique can preserve temporal continuity where there is a uniform, unrepeated physical motion or change within a passage. A match on action is when some action occurring before the temporally questionable cut is picked up where the cut left it by the shot immediately following. For example, a shot of someone tossing a ball can be edited to show two different views, while maintaining temporal continuity by being sure that the second shot shows the arm of the subject in the same stage of its motion as it was left when cutting from the first shot.


Shot reverse shot (or shot/countershot) is a film technique  where one character is shown looking at another character (often off-screen), and then the other character is shown looking back at the first character. Since the characters are shown facing in opposite directions, the viewer assumes that they are looking at each other


Thriller is a genre of literature, film and television that uses suspense,tension and excitement as the main elements.
