This video clip has no sound. It is embedded with the html5 <video> element. The video is 180 pixels high, but has an extra 18 added in the code to allow for the controls. The code for this styled element looks like this:
<video src="images/video.mov" style="float:right; margin:0 2em;" controls width="320" height="198"></video>

As with the <audio> element, the <video> element can be written to take advantage of a cascade, with browsers playing the first version in the cascade that they are able to play. Initially, I had the webm listed first, but Safari was trying to play it and failing, without moving to the next file. Currently there's a bug in the iPad which keeps it from looking beyond the first filelisted. The code for the second element looks like this:
<video style="float:right; margin:0 2em;" controls width="320" height="198">
<source src="images/video.mp4" />
<source src="images/video.mov" />
<source src="images/video.webm" />
<source src="images/video.ogv" />
</video>
