Your first question about the URL is interesting. Captions are intended to display a text alternative to sounds. The URL isn't a sound, it is already text, so why would you put it in the captions? However, within the video the URL is an image of text and WCAG 1.4.5 Images of Text requires that "if the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text". So I think you should include it in the captions, even though it will then be presented twice.

Subject: [EXTERNAL] [WebAIM] Video Questions

Hello,

I have two questions regarding videos that I'm hoping someone may know the answer to.


1. If a URL with important information is shown as text in a video but is not spoken by the presenter, is it acceptable to include the URL in the closed captions and/or audio description? If not, what would be an appropriate alternative?
2. In a prerecorded video, a banner displaying the event name appears at the bottom of the screen. When closed captions are enabled, it overlaps the banner. Does this situation violate any WCAG 2.2 Level AA success criteria?


Thanks,
Christine
