Media Alternative (Prerecorded)
Summary:
WCAG 1.2.8, "Media Alternative (Prerecorded)," is designed to ensure that users who cannot access content through video can still receive the information in an alternative format. This AAA-level criterion emphasizes the need for providing a full-text alternative for all prerecorded video content.
What:
This guideline requires the provision of a text alternative for all prerecorded video content. This text should convey the same information and intent as the video, including dialogue, actions, expressions, and any other relevant visual details.
Why:
Text alternatives allow users who are deaf, hard of hearing, blind, or visually impaired, as well as those who prefer reading over watching videos, to access the same information. It's essential for inclusivity, ensuring that content is not limited to a single format.
Examples and Scenarios:
- Instructional Videos: Providing a text document that describes the steps and processes shown in the video.
- Narrative Films: Offering a script or screenplay that includes dialogue, as well as descriptions of visual elements and actions.
- Lectures and Talks: Making available a detailed transcript or an adaptation of the content in text format.
How to Comply:
- Websites: Offer a text version of video content that users can read, covering all the information presented in the video.
- Mobile Apps: Include text alternatives for video content within the app, easily accessible to users.
- Software Applications: For any software with video content, provide a comprehensive text alternative that users can access.
Exceptions:
- Short or Supplementary Videos: Videos that are very short or serve as a supplement to text-based content might not require a full-text alternative.
- Artistic or Abstract Content: Some artistic or abstract video content where the visual experience is more about interpretation rather than concrete information may not lend itself easily to text alternatives.
