Hi All,

Wanted to thank you for this very interesting and informative conversation. 
Whilst I have nothing notable to add as I work similarly to Karl,, I have learned quite a bit from this debate/conversation.

Thank you all!!

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. http://youtu.be/ldF4eGALzvs

How far away is WebVTT (Web Video Text Tracks)? I saw this video http://youtu.be/gK72pcu3cpk a while back and thought is was just around the corner.
Cheers,
Karl

  Barry, if I understand you correctly, YouTube does actually integrate
  synchronise the transcript with the time based media. Once you provide the
  captions to YouTube in an .srt file that includes the timings, or you use
  the YouTube captions editor, then it handles everything else from there.

  When viewing the video, you can click on the 'Transcript' option and
  YouTube will display a scrolling transcript below the video.

  The other huge advantage of providing captions in this way is Search Engine
  Optimisation. search engines like Google can index every word of the
  transcript, and can drive searches towards the video based the words spoken
  in the video. Normally, it would just index the video title and
  description.

  Hi Shane -

  Thanks for that; I wasn't actually aware of that technique, so
  it's very handy to know. Can you point me to an example where
  that works? (I tried just on a random youtube video that did have
  captions, but couldn't spot a "transcript" option; so either I'm
  looking in the wrong place in the interface or it relies on
  something more than just having a captions file provided.)

  And of course I agree with your point on the search engine
  benefits of captioning and transcripts; though this is not quite
  as clear cut as it used to be. Google, in particular, are
  progressively using their automatic speech recognition (which
  underpins the offer of automatic captioning, when a captions file
  has not been provided with the original media file) to facilitate
  this. The quality of this automatic recognition/transcription is
  still very variable, and rarely very satisfactory for captioning
  as such; but because of the redundancy involved in the search
  indexing, it actually does quite well for that purpose (even if a
  word or phrase is mistranscribed one or twice, if it is central
  to the content it will occur repeatedly and is likely to be
  picked up correctly at least once). Of course, a proper, human
  generated, transcript will always be better; and the latter can
  also incorporate transcription of any audio description track
  which will further enhance indexing. So proper captioning and
  transcripts are certainly still a search optimisation tool; but
  just not quite as definitively so as in the past.

  (Incidentally, the same story applies to "scanned PDF" material
  on the web: it seems that google does use OCR routinely to
  attempt to index it. The OCR quality would typically not be
  adequate for accessibility purposes, but on the principle that
  "something is better than nothing" it does generally
  significantly improve search engine indexing. I recently
  experienced this for real, where I played the "search engine
  optimisation" card to try to persuade somebody publishing scanned
  PDF material to do properly accessible PDFs; but the response was
  exactly that they had found that the documents seemed to be being
  indexed in google perfectly well already!)

  Best wishes - Barry.

  Sorry Shane, I've spotted the transcript button now (for anyone
  else similarly confounded, the button is "hidden in plain sight"
  in the bar with the "like" and "dislike" buttons; i.e., not
  within the player controls or in the caption options where I was
  studiously looking for it. Live and learn!)

  Best regards - Barry.
