For example, media player software might be used to combine closed subtitles with the video itself. However, displaying closed subtitles is optional since they are overlaid onto the video by whatever is playing it. Open subtitles are always shown whenever the video is played because they are part of the video itself. Third, subtitles need to be displayed to the audience. In either case, there are a wide variety of technical approaches and formats used to encode the subtitles. On the other hand, closed subtitles are stored separately, which can allow subtitles in different languages to be used without changing the video itself. Open subtitles are added directly to recorded video frames themselves and thus cannot be removed once added. Second, subtitles need to be distributed to the audience. Regardless of who does the writing, they must include information on when each line of text should be displayed. Subtitles written by fans, rather than more official sources, are referred to as fansubs.

When there is plenty of time to prepare, this process can be done by hand. First, the text of subtitles needs to be written. Quotation dashes are used to differentiate speakers.Ĭreating, delivering and displaying subtitles is a complicated and multi-step endeavor.
