I actually was shooting a parody of the Apple “switch” ads and inadvertantly was able (pretty easily) to get the ipod video also. I shot in a racquetball court (white background, ambient light). Then pull up the contrast/brigthness a bit and you’ll have a solid white background behind your subject. Play around with a threshold filter, and your sujbect should turn all black. Then just add a green solid and set the blend mode to multiply. Bingo.

Good luck,
