WCAG 2.1 Level AA compliance for video requires making video content accessible to individuals with disabilities. Key aspects include:
- Captions: Providing synchronized text captions for all prerecorded audio content, and for live audio.
- Audio Description: Offering audio descriptions for all prerecorded video content, narrating important visual information during pauses in dialogue. Alternatively, a descriptive transcript can be provided.
- Transcript: Supplying a text transcript that includes both the audio and relevant visual information. This is essential for video-only content.
- Keyboard Accessibility: Ensuring all video player controls are navigable using a keyboard.
Essentially, the goal is to provide equivalent information and functionality for individuals who cannot see or hear the video content.
