video element transcript
video elements must have all audio and visual information available in a transcript.
This conformance rule relates to:
A text transcript containing all the visual and auditory information of the test target is available, either on the page or available through a link.
Note: A “text transcript” in the context of this rule is defined in WCAG 2 as a alternative for time based media.
This rule assumes that a mechanism is available to start the video and that the video element is not simply used to display the poster.
There are no major accessibility support issues known for this rule.
A video element with a text transcript on the same page.
A video element with a link to a text transcript on a different page.
A video element with an incorrect text transcript on the same page.
A video element with a link to an incorrect text transcript on a different page.
A video element that is not visible on the page.
A video element without audio.
Content perceivable through sight.
Content is considered visible if making it fully transparent would result in a difference in the pixels rendered for any part of the document that is currently within the viewport or can be brought into the viewport via scrolling.
