Right now, in all of the browsers that I tested, turning images off
has no effect on the rendering of video. There is no way to turn off
video rendering in browsers right now.

No, it doesn't. It has video controls rendered and it is clear to
everyone that it is not an image but a video.

No, that is not my position. My position is that we need
aria-describedAt and that the link that aria-describedAt links to can
present all the different types of long descriptions that are needed.
I still have to write a demonstrator of what I mean to make it clearer
what I mean.

But I do indeed believe that with aria-describedAt and aria-label,
aria-labelledby and aria-describedby we have short and long text
alternatives covered. I therefore don't subscribe to the need of issue
