Run graphics through a contrast checker to ensure that they are meaningful to those with impaired vision, including color blindness.

Captions are an essential feature of accessibility. To ensure accurate captions, do this by using the MediaSpace captions tutorial.
All videos must be ADA compliant. ADA compliance means everyone can benefit and learn from instructional videos. Videos must have an edited caption track, which means no one can fully rely on automated captions. Technical terms and Southern accents are frequently misinterpreted by automated caption services. Regional accents and the voices of folks who speak English as a second language are important facets of representation and should be included in videos. Further considerations:
Upload a transcript with the video. Ideally, this would include a visual description of the video and all audio effects.
