You must provide an accessible alternative way of presenting the information in a video.
In a video information is presented in a variety of ways including animation, text or graphics, the setting and background, the actions and expressions of people, animals etc. Video-only content is inaccessible to people who are blind and to some who have low vision.
People who are deaf or have limited hearing cannot hear the audio. Therefore, it is important to have alternatives.
