For those interested in watching, it's giving a great overview of what
practicing Web captioners deal with today.

I found that before minute 16 it is all about TTML.
After that it's about WebVTT and SMPTE-TT.
At 20m min Michael talks about the former problem we had with
https://dvcs.w3.org/hg/text-tracks/raw-file/default/608toVTT/608toVTT.html#browsers
and the on-screen text states that we had corrected the problem.

I assume, Michael, that you gave this talk a before we made the fix?

Also, Michael, you might be curious to learn that all browsers by now
support WebVTT natively through the <track> element - alas not all the
features, e.g. IE doesn't do any placement or coloring, and Firefox
doesn't support CSS on captions yet.

Cheers,
Silvia.
