A subtitle is a time-coded transcript whereby the spoken words in a video/audio file are split into small chunks, each of which has a start and end time that match when those words are spoken in the source file.
A subtitle can be used to appear to display the spoken text on the video, allowing the user the option of reading the spoken text instead of, or in addition to, listening to it. The subtitle file can be “open” or “closed”. The former cannot be turned off by the viewer, whereas a closed subtitle gives the viewer the option of displaying or hiding the subtitle.
We can provide the subtitled file in many formats, including SRT (SubRip Text), TTML (Timed Text Markup Language), WebVTT (Web Video Text Tracks), SMI (Synchronised Multimedia Integration), SCC (Scenarist Closed Captions), and many others.
