Robert, when you say "burned in" are you referring to time-stamp text files included in the media wrapper, of converted to a binary format (.scc) and merged with the video asset as pixel data? If it is the later, it makes it impossible to repurpose that text to AT like screen readers and Braille refresh bars. As well, from experience this type of post-production is often outside the capacity of smaller and non-professional video producers, which raises the bar of entry. I expect to see loads of TextAssociation type content emerging - certainly in the nearer future. Can you clarify? (I'm pretty sure that's not what you mean, but the limitations of email...) Cheers!
