A transcript is a retrospective written record of dialogue, and like a script (a prospective record) may include other scene information such as props or actions. In the case of a transcript of a film or television episode, ideally it is a verbatim record. Because closed-captioning is usually written separately, its text may have errors and does not necessarily reflect the true Canonical transcript.
