Hi All,
Interesting conversation. I think everyone on this list would agree video
content must be as accessible as possible. There is no denying however that
achieving this is costly in terms of resources. I did a video a while back
on using (and editing) the automatic captioning on Youtube a a quick and
easy way of subtitling videos. It's a great time saver if you haven't
scripted your videos first. Just upload the video and let Youtube/Google
figure out the timing and make an attempt at recognising the speech. Then
download the .srt it has created and correct it as needed. I find this
approach much easier than using a subtitling application.

How far away is WebVTT (Web Video Text Tracks)? I saw this video
http://youtu.be/gK72pcu3cpk<https://owa.enableireland.ie/exchweb/bin/redir.asp?URL=http://youtu.be/gK72pcu3cpk>
a
while back and thought is was just around the corner.
Cheers,
Karl
