Why VTT for captions

VTT is the right format for accessibility-critical web embedding:

• Native browser support with <track> element
• Supports sound description cues ([music], [applause])
• Auto-selects language based on user preference
• Matches WCAG expectations via <track kind="captions"> semantic

For the WCAG conformance context, see YouTube captions and accessibility.

Captions vs subtitles: pick the right track

For accessibility work, pick the manual caption track — uploaded by creator or contributor. Manual tracks are more likely to include sound description.

For the terminology, see captions vs subtitles.
