Burned-In Captions

Burned-in captions — also called open captions or hardcoded subtitles — are text overlays that have been permanently rendered into the video image. Unlike closed captions (CC), which exist as a separate data track that viewers can toggle on or off, burned-in captions are baked directly into the pixels of each frame. If the video plays, the captions play. There's no off switch. This makes them the opposite of flexible, but also the most universally compatible option — they appear on every player, platform, and device without requiring any special caption-rendering support.

The demand for burned-in captions has surged dramatically with the rise of social media video. On platforms like LinkedIn, Instagram, and TikTok, videos autoplay in feeds without sound. Viewers scrolling silently either engage with captions or scroll past. Studies consistently show that 85% or more of Facebook video is watched without sound. Burned-in captions are the most reliable way to serve silent viewers, because they don't depend on the platform implementing closed caption support correctly — they're just part of the picture.

The trade-off is rigidity. Once captions are burned in, correcting a typo means re-exporting the video. Translating the video into another language requires creating an entirely new export with different captions rather than simply swapping out a caption file. For B2B teams producing high-volume content for multiple markets, closed captions offer far more long-term flexibility. The practical approach many teams use: maintain a clean master without captions, burn in captions for platform-specific social exports, and deliver closed captions with the master version for website embeds and formal distribution.
