This command looks fine to me, other than the fact that it will produce
a video that is 320 pixels wide. Does this work on your iPod?

I was expecting a command that would give you a video that is 640 pixels
wide because that's what your email subject is about.

Does ffmpeg fail, or does iTunes not accept the file, or does the iPod
not play it?

You're using a recent ffmpeg. That's good.
