Make videos and audio files more accessible
From EdTech Help
When you include video or audio content in your document, you must provide an alternative method for your audience members to understand the content if they cannot hear the audio or see the images in the video. You can improve video and audio accessibility by providing transcripts and captions, and descriptions of video images.
Please contact your institution's office for Disability Student Services and/or Information Technology Services for students to get help with accessibility issues and for instructors to get help with adapting their course content for accessibility.
