This document discusses several important editing concepts used in film and television including:
1) Shot reverse shot is used in conversations to cut between characters as they talk and react to one another.
2) Matching involves cutting between shots where one object or action blends into another, such as steam blending into steam.
3) The 180 degree rule is important for continuity and prevents jump cuts by restricting filming to one side of an imaginary line around the action.
4) Match on action cuts between shots where a character reaches for something off screen to the object being reached for.
