Making Web content and video accessible to people with disabilitiesis the law. Ensuring a video is accessible requires planning. Taking steps from day one will save you time and money.

When you watch a video on your computer, the window that displays your video is called a “video player.” It usually has start, pause, and other buttons. You might not be aware that you’re using a player at all—you just watch your video. A fully-accessible video player (e.g. Section 508-compliant) can be used by a person with disabilities, including, for example, someone who may be paralyzed and can’t use a mouse.
What are Audio Descriptions? Audio Description, also called descriptive video or video description, is an additional audio track that describes and gives context for essential visual information. Audio Description makes videos and multimedia accessible to people who have “low vision” (very poor vision), or who are blind, by capturing what is happening on screen into audible descriptions that are played during natural pauses in the audio track. Here is a video that explains why audio descriptions are important to include.
What are Captions? In a video, captions collect all audio information and describe them using text. They include not only spoken content but also non-speech information such as sound effects, music, laughter, and speaker identification and location (for example, audio spoken off-screen). Captions appear transposed over the visual elements in a video, and are synchronized so they appear at the same time as they are spoken or generated.
