Well, I believe that Quicktime can play uncompressed AVI files but I
don't think most people would appreciate downloading the extremely large
files you'll generate. The reason you would generate uncompressed .avi
files is that you don't want to lose image quality when re-encoding the
video in QuickTime (or whatever program you ultimately use).

Your original file was 180 MB. Compressed in Windows Media Encoder
(free) as a 5Mbps "Hi-def" video you end up with a file that is 84 KB.
KILOBYTES! 0.04% of the original videos size. And it looks great. I
also ran it thru the Indeo Video 4.5 and 5 encoders. The output file
was ~280 KB. 0.15% of the original. Still not bad but I couldn't avoid
some ghosting around the red box in the video so it may not be the best
choice. Neither of these codecs are playable in Quicktime but you get
an idea of how much you can compress your animation. I also noticed
that I didn't have Indeo 4.4 on my machine so it may not be available
anymore.

My guess would be that with Quicktime Pro you could get results similar
to the .wmv. If you have $30 to spend I would do that as it is by far
the simplest way. If not, there are opensauce programs that you can
cobble together to encode your uncompressed AVI (check out ffmpeg).

Case in point, it took ~10 minutes to download.
