Thanks, Myra. That's the process I used. As it turns out, the problem was not that the Alt text didn't get included -- I finally discovered it was there. It's just that when you "inspect" the element, the block of code the browser highlights is just one of MANY blocks of code pertaining to the video element. It's not the one that contains the Alt text. You really have to scroll through the adjacent lines of code to find the div that contains the Alt text. Since I was having trouble finding it, I figured it wasn't there. But it is. Just buried in a lot more code than there is for still images.
