One day I heard the song Reset by Mute Math and I liked it a lot. Then I thought 'Hey, I'm learning After Effects! Why not make a music video?' This video took me a few days to make. However, this wasn't nonstop working. I'd put in a few hours every day. I am quite proud of it, as it is one of the few videos I have actually finished. There is no plot, no anything; just shapes and colors to the beat of the music.
[TECH STUFF] Rendering took 3 and a half hours in AE CS4. When it was done, however, the file size was 25.5gb. I couldn't do much with a 25gb file (I couldn't even watch it without lag), so I used DivX to compress it to 164mb with absolutely no noticeable quality loss (how DivX does it, I don't wanna know...). That's about 21 times smaller, for all you math enthusiasts (no pun intended).
Just sit back and enjoy the ride :)
UPDATE: A number of people have requested that I offer download links to the video, so if you go over to Vimeo you can download it from there: https://vimeo.com/6375633
