That would be depend on what the author wanted to present also. 
E.g. consider that the video only contained a short part of the 
speech, that place where everything went horribly wrong etc.

I complained that Henri took <video> to mean commercial video. But 
I think here you mix the name "longdesc" with "long description". 
"longdesc" is a bad name for something which is meant to represent 
  "a long or complex alt".

This is not in line with what @longdesc is in HTML 4. In fact, if 
anything, it would have been the @alt which contained what you say 
the @longdesc resource should contain. Consider the  example code 
in the HTML 4 specification:

<BODY>
<P>
<IMG src="sitemap.gif"
      alt="HP Labs Site Map"
      longdesc="sitemap.html">
</BODY>
