What makes a video accessible?

• Captions

  Captions are text representing spoken words, such as dialogue or narration, and other meaningful sounds in the video.

• Descriptive transcript

  A descriptive transcript is a full text equivalent of the content in a video — that is, of all the meaningful audio and visual information presented in the video.

• Audio description

  An audio description is an additional audio track that’s added to the video to describe and give context for essential information that’s only presented visually on the screen.

• Sign language translation

  New Zealand Sign Language (NZSL) is one of New Zealand’s official languages. People in the Deaf community use NZSL to communicate.

• Autoplay is disabled

  Autoplay is where a video is set to start playing as soon as the web page loads — it’s best to avoid this.

• Title attribute, if video published in an <iframe>

  The HTML title attribute lets people using a screen reader know that a video is present and what it’s about, so that they can play it or skip past it if they want to.
