Why video accessibility still starts with captions
Captions help deaf and hard-of-hearing viewers — and anyone watching on mute. A short case for shipping them on every clip.

Captions are the baseline accessibility feature for video. They also help people in quiet offices, loud trains, and second-language viewers who read faster than they listen.
Ship captions by default
- Treat auto-captions as a draft, not a publish button.
- Keep contrast high and type large enough on mobile.
- Identify speakers when dialogue matters (interviews, podcasts).
- Offer SRT/VTT when the platform supports separate tracks.
