Burned-in captions are subtitles that are permanently embedded into the video image. Unlike optional closed captions, they can't be disabled or hidden by the viewer.
They guarantee accessibility across all devices and platforms—even where subtitle toggles are unavailable. Especially useful for social content, ads, and international distribution.
Use burned-in captions for mobile-first content, trailers, or where autoplay is likely. Ensure high contrast and legibility across screen sizes. The tradeoff: burned-in captions reduce flexibility since they can’t be edited or hidden.
Ensure readability – Use high-contrast fonts with proper sizing and safe-zone placement.
Check timing accuracy – Sync captions closely with dialogue and sound cues for accessibility and comprehension.
Keep text concise – Break long lines into readable chunks that match natural speech pacing.
