Why is it called a trailer?
A “trailer” is a movie preview that is often shown in a theatre before a feature film. This word was originally used because these clips were shown after a film. They trailed at the end. As a trailer editor, you cut and edit film footage to create a preview trailer for a movie. In this role, you may help decide which scene or scenes to highlight in the trailer and work to fulfill a specific advertising or project goal.
Who are trailers aimed at?
Trailers are generally aimed at the same audience as the films they publicize. Different types of people like different sorts of films and whilst everyone is an individual there are certain features that will have wide appeal to specific groups of people. It doesn’t take much for a trailer to tip from hints into full reveals. If the film isn’t very good or is more languidly paced than we’re told mainstream audiences desire, the trailer will pad things out with those big moments as a hook, even if it gives everything away.
