Step 1 was to extract several thousand still frames from the original movie. Easily done if you have a copy and know how to use mplayer’s video filters.
Step 2 was to take the Speed Racer trailer and extract the individual frames and soundtrack. Again, easily done with mplayer.
Step 3 is as simple as doing some magic foo with your mosaic tools so you end up with mosaic versions of each trailer frames, using the original movie frames as tiles. Easy but slow.
Step 4 is to put the mosaic’d trailer frames back with the soundtrack and encode it all with mencoder. Doodle.
