I used my Sony Cybershot digital camera to take a video of my
presentation at Democamp
last night. The file weighed in at 400+ MB! After a bit of trial and
error, I figured out how to use mencoder to crop to just me bouncing
up and down and talking excitedly about Emacs. =) Here's the
incantation I'm currently using:

mencoder -ss 111 -vf crop=275:300 mov07578.mpg \
         -of mpeg -oac mp3lame -ovc lavc -o emacs.mpg

I might need to tweak it a bit more. Still, mencoder is fun!
