I read some interesting ideas on a website about mosaic on videos. It suggested a combination of Virtual Dub and Video Enhancer. The idea is you reduce a decent quality video down to 1/4 or 1/8 size, then you use Video Enhancer to increase the size back up to original size.
I did try this but the results were quite horrible, due to the quality loss in the two programs output conversion it seemed to me. Anyway the idea seemed sound so I tried a simpler, and quicker way: I used VLC to quarter the video size (a compromise, since it was my opinion that 1/8th is too far), keeping the output video rate decently high and not frame converting it. It was able to create a shrunk video in about 1/4 of real time. Then I simply played out that shrunk file using the video card's tv-out again on VLC recording the output to a hard drive dvd recorder. I have to say I think the results were pretty good, vlc itself doing some pretty fine interpolation on the resize. The process reduces the mosiac enormously, though of course you get a somewhat deteriorated picture in general as the down side, but not as bad as you might think!
