This document outlines 5 main editing concepts in film: 1) Establishing shots are used to set the context of a scene by showing the relationship between characters and objects. 2) The 180 degree rule ensures the same space is depicted in each shot based on character and object placement. 3) Shot/reverse shot technique alternates between showing one character looking at another, often off-screen. 4) Editing transitions describe how one shot moves into the next, creating different meanings, such as fade to black or jump cuts. 5) Shot duration reflects narrative context, with short shots conveying urgency and long shots intimacy or detail.
