No previous message | Next message →

We're trying to find some info on the best approach to inserting videos
into Powerpoint files without making them inaccessible. The video we're
trying to insert has captions, but JAWS and NVDA both don't see the video
or player controls. We've thought about just dropping a link to a web page
where we can embed a video with a player that supports captions. We're
trying to avoid requiring users to install add ons, since we are publishing
these files publicly. Are there any resources or recommendations that
anyone has that could help guide our approach?

thanks,
Levon

Hi,
I think your only hope is having those linked from something like
YouTube or a bundled HTML page.

Some some of our PowerPoints have longdescs that have structure (like
tables as longdescs for charts/graphs), we've considered recommending
some slide decks just come bundled with an HTML page for these (then a
chart/graph/whatever can use a real hyperlink to this bundled HTML
file). Same goes for the video players. You could have the inaccessible
one still on the slides for students/instructors who want to play from
there, but the Real Thing will be an accessible HTML5 player in a
bundled HTML page.

Another benefit of an HTML file is users can access everything a browser
can offer. Users of for example Dragon can choose to open this file in
IE for getting the most control of the video player, while a screen
reader user who likes NVDA can choose to open it in Firefox.

This is what we've been doing in Product. We certainly haven't found a
way to make the video players within the PPTs accessible-- PowerPoint is
just too limited in its own capabilities :(

cheers,
Mallory

I concur, the best approach is just to provide a link to an external page which has an accessible player, like Youtube. You can import a local video, but al you can do is start it via the keyboard.

Thanks for the suggestions. We'd been thinking about posting the video
player in a web page with captions/transcript, but I hadn't thought about
keeping the existing version in the presentation.

Can't hurt, plus instructors may like being able to play if they're
displaying slides for students in the classroom (that way they don't
have to spend time switching stuff).
