That sounds interesting...


I hadn't thought of a browser, I thought about a production environment...
but a browser would be great because then you could do crowd sourcing...
people who didn't make the video could add Audio Description the video...


(of course, that could be a prime form of "spam" too..)


Perhaps it would have to be an account driven thing...

Hi David,


We definitely want to make this as easy as possible.  What we are
envisioning is a system that wouldn't require re-export of the video, we
would record audio in the browser or have a user upload mp3 and then play it
back with javascript, time-aligned to the video file.  Essentially it would
be the same system that we use for subtitles, but instead of text, it would
be audio-- it could be switched on or off at any time and it would travel
with the embed.  It wouldn't require uploading a second copy of the video
with the audio track.


The vision is this-- someone can record audio right from their browser,
tweak timing if necessary and they are done.


What do you think?

Hi Nicholas


Nice to hear from you... I'm a former audio recording musician, so I have
quite a bit of experience in commercial multi track audio recording


yes I think we need an easy cheap way to put audio descriptions into a
video, that would be great... just load up the video into the recorder, plug
a mike into the computer, the recorder will auto detect the input source,
and user hits the record button and talks, and stops, and pauses...I think
for these simple talking heads, the idea of just reading in real time
against the video, and exporting with the existing audio is probably the
easiest ... then there are no DFXP type timing codes or SMIL and all that...


The recorder just lets you try to speak in the cracks,  just like a real
time multi track audio recorder like Cubase or Audacity does,


The user can just delete and rerecord as necessary until its right, or they
can nudge around their AD track in the recorder, then export the AD  version
of the movie once it's right ... it could be posted on the server as an
alternative video to the original, and then the player could have an AD
button on it... and when the AD button is pressed, the video is swapped out
for the version with AD....

Hi David,


As Gregg mentioned, Universal Subtitles, which has a very flexible system
for aligned text, will be adding support for time-aligned audio sometime in
the near future. 


I'd love to chat sometime so that I could better understand what your needs
and requirements are for this kind of stuff, I think there's a lot of
options, at least on the tech side, that could make things simpler for you.

Hi David,


            if there is a talking head - then there usually isn't any space
for description anyway.


            Also - the point is to allow a person who is blind to access key
visual information.


            On key part IS the front end of the video where they usually
have an identification of the speaker.  OR during the video - where they
overlay the screen with text identifying the speaker. 


            It would be good to get audio into those places if there is a
pause in the regular audio.


            I think this is a  GREAT place for an online tool (or free
downloadable tool) that would allow people to add a few short descriptions
to a video for these types of situations.   It would not have to be done by
"talent" if non - commercial.


            we also should work more on "closed description" mechanism which
should be easy in IP to allow video description to be available on request.

I've been coming across a lot of this lately, and don't really know what to
do about it... we have a requirement for audio descriptions... but 95% of
all video on Government and corporate sites are just talking heads, like a
message from the CEO, or from the marketing manager, or from the Minister,
where he's just talking in front of a non-consequential background.


Honestly, it seems extraneous to require these videos to be audio described
which can cost thousands of dollars, and provides almost zero value for a
person who is blind...


We could I guess get a voice overdub at the front that says... "the minister
speaking in his office, with a flag in the background" ... but I almost wish
we had some kind of an exception for these videos of talking heads... it
would cost a thousand bucks for that line, (unless there is some kind of
internal production facility).
