Broadcast Closed Captions 

Capital Captions offer closed caption services for broadcast. For production companies, it is a legal requirement for television programmes, films, documentaries or dramas to feature closed captions encoded into the television in Line 21 to accompany your video content. Broadcast closed captions are a legal requirement, and we offer high quality, reliable, affordable writing, formatting and encoding services to suit your needs. 

Closed Caption Writing

Closed caption writing requires a high level of experience. As a result the process involves a number of stages, which are outlined below: 

  • Video Transcription of speech
  • Addition of sound effects, nuances of speech and changes in tone
  • Identification of speakers, usually when off-screen
  • Proofreading formatting style of the above in accordance with channel regulations and also client preferences
  • Splitting of text lines within the closed captions file
  • Timing of onscreen text to sync with video content

closed captions vs open captions 

The term ‘closed captions’ is widely recognised as referring to onscreen text displayed on television and video services. This definition covers the ‘captions’ aspect of the terminology, but what is the difference between ‘open’ and ‘closed’ captions? 

About Open Captions 

Open captions are always visible on a video. An open captions file is effectively burned onto the video stream, similar to subtitles, and is no longer recognisable as a text file. This can potentially mean a loss of quality when video files are compressed. Closed captions require a viewer to turn on the text, which is encoded into Line 21 of the television signal. The text file is preserved and kept separate from the video stream. Consequently the viewer takes on responsibility of knowing how to turn on closed captions on their television set.
