## Captions & transcripts

**Captions**: all dialogue + sound descriptions. **Subtitles**: dialogue only, usually for translation. **Transcript**: text of all audio. Required for WCAG AA video content.

## HTML5 video with captions

Use `<track>` element to include captions in VTT format.

```html
<video controls aria-label="Tutorial video">
  <source src="tutorial.mp4" type="video/mp4" />
  <track 
    kind="captions" 
    src="captions-en.vtt" 
    srclang="en" 
    label="English"
  />
  Your browser does not support video.
</video>
```
