It's just captions, right? Why does video accessibility matter in the 21st century.
summary
Video accessibility matters because laws (ADA, Section 508, CVAA) and FCC metrics force real technical requirements: captions must meet completeness placement accuracy timing, and auto‑captions routinely fail those measures so manual transcripts remain the reliable solution. HTML5 supports WebVTT and multiple audio tracks but browsers and players lack consistent UI for switching descriptions. Audio description needs scripted narration, synchronized or using extended playback, and some projects (Cities Unlocked) ship two synced cuts because in‑player switching isn’t yet solved.
