How to hardcode subtitles? A complete guide for 2026

If you upload videos on social media, you are likely already familiar with the issues of soft subtitles.

This is why nowadays we see hardcoded subtitles (also called open captions) on most of social media videos.

Let’s see in detail what exactly hard-coded subtitles are and how to hardcode subtitles.

What are hardcoded subtitles?

Hardcoded subtitles, sometimes also called burned-in subtitles, open captions, or hardsubs, are subtitles that have been permanently added into the actual pixels of a video. It means the text becomes part of the video itself permanently, just like a watermark or a logo.

Once a subtitle is hardcoded, it cannot be turned off, changed, or removed. It will also appear on every device and in every player, regardless of subtitle settings or compatibility.

You can think of hardcoded subtitles as printing text directly onto an image with a marker. The words are now part of the picture and not a sticker you can peel off.
