Captioning Videos

Multimedia is the integration of multiple forms of media which may include text, graphics, audio, video, and animated content. Supplementing information presented with multimedia through the use of captioning and transcripts can enhance the user experience for people with different learning styles and preferences. In order to be fully accessible to the widest possible audience, videos should be captioned and a transcript should be provided. See "Video Captions Benefit Everyone".

About 20 percent of Americans, approximately 48 million, report some degree of hearing loss. Sixty percent of the people with hearing loss, over 28 million, are either in the work force or in an educational setting (hearingloss.org). In this instance, captions, used in conjunction with transcripts, provide a text alternative to audio content and are essential in providing equivalent information. This allows the content to be accessible to those who do not have access to audio as well as those who may be hard of hearing or deaf.
