What Are Forced Subtitles?

Forced subtitles appear even when the viewer has subtitles turned off. They cover only what a viewer in the film's language would otherwise miss: dialogue in another language, signs, letters and on-screen text. Streaming services call them forced narrative subtitles.

Example
movie.mkv
movie.en.srt          full English subtitles
movie.en.forced.srt   only the Russian scene and on-screen text

Where you see them

A character in an English film speaks Russian for one scene, and English lines appear just for that scene. A text message on a phone screen gets a translation. Everything else stays unsubtitled.

How players know a track is forced

Video containers such as MKV and MP4 can flag a subtitle track as forced. SRT has no such flag, so media servers like Plex and Jellyfin rely on the file name instead, for example movie.en.forced.srt.

Forced subtitles when translating

When you localise a video, the full subtitle track replaces forced ones for viewers who turn subtitles on, but viewers who don't still need the forced lines translated — they are a separate, short file.

Questions

Can I turn forced subtitles off?

Usually not from the subtitle menu, because they are meant to stay on. Some players let you disable them in settings.

Why don't my forced subtitles show in Plex?

Check the file name ends in .forced.srt and that the language code matches the audio track.

Are forced subtitles the same as burned-in subtitles?

No. Forced subtitles are still a separate track that the player turns on automatically; burned-in text is part of the picture.

  • SDH subtitles

    SDH stands for Subtitles for the Deaf and Hard of Hearing. Besides the dialogue, SDH subtitles name off-screen speakers and describe sounds that matter — [door slams], [phone buzzing], [tense music] — so the video makes sense without audio. Streaming services label them, for example, English [SDH].

  • Open captions

    Open captions are captions burned into the video itself, as part of the picture. They are always visible, look the same on every player and platform, and cannot be switched off — unlike closed captions, which come as a separate track the viewer can turn on or off.

  • SRT file

    An SRT file (SubRip Subtitle, .srt) is a plain-text subtitle file. Each subtitle is a numbered cue with a start and end time and one or two lines of text. Players and platforms show the text over the video at those times, and viewers can switch it on or off.
