Audio Description
Answer
Blind users who encounter videos will be able to hear what is said, but unable to see the visual components of the video. While it is possible to add audio description to videos after they have been created, it's a best practice to design video scripts so that the original audio describes what is being shown visually.
Examples:
Do
- Review and edit video scripts and storyboards to include descriptive narration of visual components that doesn't rely only on sensory characteristics.
- consider what you want users to get from visual elements and incorporate this into narration.
- describe visual components of synchronous or live virtual events.
