Media Accessibility

If you're dealing with video or audio content, this handles the WCAG 1.2.x audit work: checking for caption tracks, validating WebVTT and SRT files, verifying transcripts, and auditing media player controls for keyboard access and proper ARIA. It covers the full spread from prerecorded captions to live streaming requirements and audio descriptions. The caption quality checks are solid, looking at sync timing, speaker identification, and readability limits. Honestly most useful when you're trying to hit Level AA compliance and need someone to systematically walk through every media element on your site rather than guessing what's missing.
