I agree with Charles on all points.

One small point:  regarding interactive transcripts, I wouldn't classify them as either common or well-understood.  They aren't used *that* widely, nor are they particularly well-liked  (anecdotally speaking) in the caption-viewing community.  The motion that is often inherent in an interactive transcript-- either a moving box/highlighting region or scrolling text-- can be distracting and difficult to read when trying to watch a video.

What happens if the transcript element is placed inside the video element? Does it still need the transcript attribute? Or does it *have* to be placed outside the element?

Experience suggests that people do that with anything they *think* is just for accessibility, and that they do it in ways that range from not very good to completely broken.
