[iTunes] video format for iPod Nano?

[Becca]

What's the video format that you can put on an iPod Nano (3rd gen, I think - the short, squat one)? is it MP4? I'd like to download the Symphony of Science video from the site, and that's the format it's available in.

A still more glorious dawn awaits
Not a sunrise, but a galaxy rise
A morning filled with 400 billion suns
The rising of the milky way
