Version and Level: 2.0/2.1/2.2(Level A)

WCAG SC 1.2.1 focuses on ensuring accessibility for prerecorded audio-only and video-only content on websites. It requires providing alternative methods for conveying information to accommodate users with various disabilities.

Benefits:

  1. Inclusivity: Making audio-only and video-only content accessible ensures all users, regardless of disabilities, can access and understand the information.

Main Objective:

The main objective of WCAG Success Criterion 1.2.1 is to provide alternative methods for conveying information in prerecorded audio-only and video-only content, ensuring equivalent access for all users.

Best Practices:

  • Audio and Transcript Placement: Ensure the audio track and the transcript, or a link to it with a proper description, are positioned next to the video-only content. If the transcript is placed in a different area such as a pop-up or a separate page, provide a link with a description for easy access.

  • Silent Video Accessibility: For silent videos (video-only), offer either a text transcript or an audio track to ensure accessibility.

  • Exception for Audio Tracks: If an audio track is provided for a video, a text transcript may not be required, but it's recommended for comprehensive accessibility.
