Checkpoint 1.3 requires that you add audio descriptions of the important 
visual content to your video. These are additional descriptions and can 
be added using a tool like MAGpie 
(http://ncam.wgbh.org/webaccess/magpie/). There are some good 
instructions available, see: 

Checkpoint 1.4 requires that you add captions of all the spoken and 
other audio content to your video. These can also be added using MAGpie. 
  An example of captioned video can be found at: 
(choose the download option). Some good instructions are provided by 
WebAIM: http://www.webaim.org/techniques/captions/

In addition to this you also need to provide a text equivalent according 
to Checkpoint 1.1. This text equivalent must include *all* important 
visual and audio content.

If complying with Checkpoint 1.3 and 1.4 is too onerous, you could 
consider using the clause provided by Checkpoint 11.4: "If, after best 
efforts, you cannot create an accessible page, provide a link to an 
alternative page that uses W3C technologies, is accessible, has 
equivalent information (or functionality), and is updated as often as 
the inaccessible (original) page." Essentially this means if you provide 
a transcript (as per Checkpoint 1.1) and it provides the equivalent 
information (ie describing important audio and visual information) then 
that will be sufficient for your site to pass Level A of the W3C Web 
Content Accessibility Guidelines.

If you are aiming for Level AA then you will need to comply with 
Checkpoint 1.3 and 1.4.
