Videos are great and they should be produced and delivered in ways that ensure that all members of your audience can access their content. Providing captions, audio descriptions and transcripts make your videos accessible to a wide audience,
Why making videos accessible is important?
- Video captions not only benefit those who are deaf or hard of hearing, but people who are learning disabled, ESL learners, those who are in a quiet public environment and don’t have access to headphones (such as a library).
- Video captioning improves comprehension and retention of information.
How to create accessible videos:
- Create captions, a transcript, and audio descriptions for your videos.
- YouTube provides automatic captioning, however it is not without errors. If you use the automatic captioning, edit out errors.
- Make sure it is delivered in an accessible media player.
Captions are text versions of the audio content, synchronized with the video.
- Open captions are part of the video and cannot be turned off.
- Closed captions are not part of the video and can be turned off and on.
- YouTube’s automatically generated captions are a good STARTING point but they need to be manually checked to fix errors.
- Jessica Kellgren-Fozard is a great teacher and champion of captioning. These 4 videos cover the importance of captions, how to caption, and captioning best practices.
Audio Descriptions are commentary and narration which guides the listener through the movie, tv show, theater or other art form with concise, objective descriptions of new scenes, settings, costumes, body language, and "sight gags," all slipped in between portions of dialogue or songs.
- Audio Descriptions help with accessibility for people who are blind, have low vision, or who are otherwise visually impaired.
- Audio description supplements the regular audio track of a program.
- Audio description is usually added during existing pauses in dialog.
- Audio description is also called “video description” and “descriptive narration”

- Transcripts allow anyone that cannot access content from web audio or video to read a text transcript instead.
- Transcripts provide a textual version of the content that can be accessed by anyone. They also allow the content to be searchable, both by computers (such as search engines) and by end users.
- Screen reader users may also prefer the transcript over listening to the audio of the web multimedia.
