Multimedia refers to the integration of text with video, audio or image files in electronic content. To ensure accessibility of multimedia content on the web, learning management systems, electronic communications, etc., alternate forms to represent the information should be provided.
Accessible video & audio
To be accessible to most users, video should include captions, a transcript and audio description in an accessible media player. According to a 2016 study done by Oregon State University, students will use captions and transcripts to enhance their learning and aid in comprehension. The majority of students who participated in the study were not registered to require academic accommodations.
For audio files to be accessible, they should always be accompanied by a transcript. Before creating captions, please check the DCMP Closed Captioning Standards to learn about creating fully accessible, understandable and usable captions.
Captions & transcripts
Captions are composed of time-synchronized text of the audio content of a video while transcripts are text documents that contain all the spoken content of a video or audio file. The commonly seen captions on web video that can be turned on or off are called closed captions. Open captions, the kind that are "burned in" the video are not accessible and should be avoided. Aside from helping hard of hearing students, captions and transcripts can also assist ESL learners better understand video content. Another benefit is that it can help all students better understand technical terms in video or audio content.
At University of Washington there are to main approaches to caption your videos:
- Do it yourself
