C1Technical, Media, Accessibility
Definition
Meaning
Text displayed on screen during audiovisual content that represents dialogue, sound effects, and other audio information, intended for general viewers rather than specifically for deaf or hard-of-hearing audiences.
A subtitle or on-screen text that is always visible and cannot be turned off by the viewer, commonly used in public settings where audio cannot be played, for language support, or for accessibility.
Linguistics
Semantic Notes
Primarily used in film, television, and digital media contexts. Differentiated from 'subtitles' (which assume the viewer can hear but not understand the language) and 'closed captions' (which can be toggled on/off).
Dialectal Variation
British vs American Usage
Differences
In the UK, 'subtitles' is the dominant generic term for on-screen text; 'open captions' is a specific technical term. In the US, 'captions' is more common as the umbrella term, with the open/closed distinction being standard in media and legal (ADA) contexts.
Connotations
UK: Often associated with cinema screenings for the hard of hearing or foreign films. US: Strongly associated with legal accessibility compliance and public broadcasting.
Frequency
More frequent in American English due to stronger legal frameworks (Americans with Disabilities Act). In British English, 'subtitles for the deaf and hard of hearing (SDH)' is a more common technical phrase.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'открытая подпись' (open signature). The correct equivalent is 'несъемные/жесткие субтитры' or 'постоянные титры'.
Common Mistakes
- Using 'open caption' to refer to any subtitle. Confusing it with 'closed caption'. Using it as a verb (e.g., 'Can you open caption this?') instead of 'provide open captions for'.

FAQ
Frequently Asked Questions
Not exactly. 'Subtitles' usually translate dialogue for hearing viewers who don't know the language. 'Open captions' are a type of caption (including non-dialogue audio cues) that are permanently visible, often used for accessibility.
In public settings like gyms, airports, and bars where TVs are on but sound is off; in cinemas during dedicated 'captioned' screenings; and on social media videos where captions are burned into the video.
To guarantee the text is seen (e.g., on silent autoplay social media videos), to avoid reliance on a viewer's player/device having a caption option, or when required by a venue's accessibility policy for always-on display.
Less so. The average UK viewer would more likely say 'subtitles' or 'captions'. 'Open caption' is a specialist term used more by media professionals, accessibility coordinators, and in cinema listings.
