Below are hyperlinks and the corresponding URLs to various versions of the
video Wilf Hall Interview. The first two are the 1280×720 MP4 and
WEBM versions offered through the viewer on the principal page. The next
three are lower resolution, hence smaller files as MP4 videos. The M4V file has
chapter markers at each minute and is suitable for iOS devices and iTunes.
The last number in the file names is the target data rate in kilobits per second
