The full transcript was made by concatenating the caption text, so may not be representative. Also, YouTube does line breaks automatically when the lines get too long.

In short: for the presentations, the line breaks were done manually with LF.

Thanks for the great presentation Silvia.

How did you add line break in the captions though? I checked ‘a full transcript of the described video’ and it does not have LF where it shows them on the screen.

Aslo looks like you can move the captions on screen with mouse. How to do that?

Thanks again

@Greg – Nicely done.
I also have early demos for how to do text descriptions with ARIA live regions at http://www.annodex.net/~silvia/itext/elephant_no_skin.html and more recently at http://www.html5videoguide.net/demos/google_io/2_audesc/ . BTW to understand full WebVTT, you might want to check out the descriptions at http://leanbackplayer.com/other/webvtt.html .
