Re: closed caption vs. transcript

Hi Dan,

Captions satisfy WCAG 1.2.2. A transcript could work as an "alternative for
time-based media" to satisfy WCAG 1.2.3. That covers the WCAG level A
requirements for prerecorded video (with audio).

To be WCAG level AA compliant you need to ensure the audio track alone can
convey all the information in the video. Otherwise WCAG 1.2.5 requires that
you have an audio description with the video to describe context and/or
content that isn't conveyed with the audio.

WCAG requirements for media can get confusing very quickly because an audio
description could be used to satisfy WCAG 1.2.3. To simplify I usually tell
clients to always provide captions and a transcript, and keep the content
"radio ready" (i.e. completely understandable without the visuals).

Regards
Shane Anderson
