Creating Accessible Videos for Online Courses
The Web Content Accessibility Guidelines version 2.0 require four pieces for a video to be considered accessible. In brief, those guidelines are:
- Captions at 99%+ accuracy
- Spoken audio descriptions of relevant materials in videos
- Captioned audio descriptions of the spoken audio descriptions in videos
- Transcript that includes video captions and audio description captions

Audio Descriptions with Captions
Audio descriptions are an audio track that describe the visuals you see on a screen. You should create captions for the audio descriptions in the same way that you would provide them for the audio included with the video.
To understand what a difference audio descriptions can make for a student, please view these two frozen clips below.

The simplest way to include audio descriptions is to build the audio descriptions into your video lectures from the beginning. For instance, if you are creating a Light Board video where you are drawing a graph on the board, simply explain what you are drawing as you are doing it. If you are narrating a PowerPoint lecture, describe what is on the screen. If text is all that is on your slide, make sure you speak all the text.
DigitalGov created an excellent resource that explains the different options for including audio tracks.
A transcript should be available for the video. Once you have captions, transcripts are easy! The transcript should included the video captions and the audio description captions.
If you start with a transcript, you can also use YouTube to sync your transcript to the timings in your video.
