In one of our lessons I few weeks ago we were asked to create an animatic storyboard (using jelly) babies to act as a preliminary exercise before we actually started making our thriller piece. Whilst doing this we learnt what a Match-Cut & 180° Rule were.
A Match-Cut is a transition that involves a direct cut from one shot to another, which "matches" it in action, subject matter, or actual composition. This kind of transition is commonly used to follow a character as s/he moves or appears to move continuously.
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. The new shot, from the opposite side, is known as a reverse angle.
