Burn-in

Definition

A Burn-in (or "burned-in timecode") refers to text or timecode information that is permanently embedded (or "burned") into the video image itself, as opposed to being stored as separate metadata. Burn-ins are commonly used to create "review copies" of a film or video that include visible timecode, scene numbers, or watermarks, allowing reviewers to reference specific frames when providing feedback. Burn-ins are also used for subtitles and closed captions in certain delivery formats. The term "burn-in" reflects the fact that the text is permanently part of the image and cannot be removed without re-rendering the file.

Contextual Usage

The post-production supervisor requests a review copy: "Can you export a version of the cut with a timecode burn-in in the lower left corner? The director wants to review the cut remotely and needs to be able to reference specific frames when giving notes. Please also add a watermark with the production company name and 'CONFIDENTIAL' to protect against unauthorized distribution."
