Video With Extra Content the Captions Never Include
1.2.2 — Captions (Prerecorded)
Scenario
Setting
A crowdfunding platform's campaign page
What’s wrong
A video contains more information than the page text but has no captions — deaf users miss the extra content.
Example
On a crowdfunding platform's campaign page: a video contains more information than the page text but has no captions — deaf users miss the extra content.
Why it matters
Deaf and hard-of-hearing viewers, and anyone watching video without sound. On a crowdfunding platform's campaign page, that means they can't tell what the image or video is showing.
How to test
Play any prerecorded video with audio and check for a CC/captions control: if none exists at all, it fails.
How to fix
Caption the video whenever it contains information beyond the page text.
Outcome
With the fix in place on a crowdfunding platform's campaign page, they hear or read what the media conveys.
Who is affected
Deaf and hard-of-hearing viewers, and anyone watching video without sound.
