Entropy

Image from Wikipedia

While animated gifs are all but dead and buried (though personally I’d rather see them than a damned image map), don’t discard them altogether as they can be an easy way to make a (very) cross-platform, easy to display video file.

Obviously this tip is not for reencoding your wedding into an image and mailing it to you aunts on 56K - but if you have a small clip this works great - LH link to Ubuntu Forums finally to The 4 Steps Guide on Making Animated GIFs from Videos. Oh, and its all free!
