You might want to think twice before doing that. While not yet updated to cover some of the newest clients, Campaign Monitor's The Current State of Video in Email article covers what works and what doesn't. While the conclusion that use of animated GIFs are the way to go if you absolutely must, which makes some of us shudder, it's clear that the tried and true method of linking to a video, or some Flash application, is the way to go.

This is a great article although it does remind me of my annoyance that Flash simply does not work on the iPhone. That means when you are out and about and want to check something on your phone, you simply cannot see a video in flash form. Therefore, I always advise trying to link to a Youtube video.
