The point of the post is to teach you how to do it yourself! That being 
said, my article is more than 15 years old and things have changed, all 
for the better. You should use ffmpeg instead of mplayer, and ImageMagick 
has improved such that the "montage" command is now reasonably fast. In 
fact, you can do it with a one liner without intermediate files:

    ffmpeg -i movie.mp4 -vf framestep=24,scale=32:18 -f image2pipe
        -vcodec ppm pipe:1 | montage -geometry +0+0 -background black
        -tile 60x ppm:- movie.jpg

As noted in the original, you need to adjust framestep appropriately. This 
one-liner uses a technique described in my "Rolling Shutter Simulation in 
C" article.
