In film and animation, the editor is the person who deletes or adds scenes to a film under the explicit instructions of the director. At times, an editor may be derided for removing too much background information or sequencing the film incorrectly, but it is the director who provides this information to the editor. An additional job for the editor is to keep the sound tracks in sync with the visuals.

Most of the time, the editors save all of the footage with the final production film. This excess footage can be added later, such as added scenes on DVDs.
