Subtitle burn-in

The distinction is between open and closed captions. Closed captions travel as a separate track the player can toggle, while burned in text is baked into the pixels at export. Short form adopted burn-in because vertical feeds autoplay muted, caption toggles are buried or absent, and a styled caption is part of the visual identity of a clip.

For creators the payoff is consistency and control. Word by word captions timed to the voice act as pattern interrupts, they read identically on every platform, and they survive reposting to services that would drop a caption track. On many talking clips, adding styled captions is the single change that most improves retention.

The nuance is what you lose. Burned in text cannot be translated, is invisible to accessibility tools, and can be covered by platform interface if placed outside the safe area. It is also permanent: a typo means a re export, and a clip repurposed from another platform arrives with the original captions locked in, which is why subtitle removal tools exist.

The practical rule is to burn in styled captions for short form, keep a closed caption track for long form where translation and accessibility matter, and always position the text well inside the safe area before exporting. Proofreading names and numbers first avoids the re render that a single wrong word otherwise forces.
