Subtitles are text representations of spoken dialogue or narration in films, television programs, and other audiovisual media, often used for translation or accessibility. While they often translate foreign languages, they can also transcribe the same language for clarity or for individuals who are deaf or hard-of-hearing. Key Aspects of Subtitles
Purpose: Subtitles translate dialogue or provide a transcription of spoken language, often adding context or explaining cultural references.
Subtitles vs. Captions: Subtitles specifically focus on dialogue translation/transcription, whereas captions include descriptions of non-speech audio elements (e.g., sound effects, music) and are intended for viewers with hearing impairments. Types:
Open Captions/Subtitles: Permanently burned-in to the video and cannot be turned off.
Closed Captions/Subtitles: Can be enabled or disabled by the viewer. Formatting and Guidelines:
Length: Usually limited to a maximum of two lines, with specific character limits per line (e.g., 37 characters).
Timing: Must be synchronized with the audio, often allowing for at least 2 seconds for one line and 3+ seconds for longer, two-line phrases.
Legibility: Should have high contrast against the background, often using outlines or shadows.
Speaker Identification: Different colors or formatting can identify different speakers, particularly for complex dialogue.
File Formats: Common subtitle formats include SRT for online videos and SCC for broadcast.
Brief HistorySubtitling originated in the late 19th century with magic lanterns and evolved into “intertitles” during the silent film era. Synchronized sound films in the 1920s solidified their use for translation.
