There's two ways I can think of doing it. One way is just messing entirely with the camera you're using- by changing the white balance so everything is blue, and also (if your camera is as crappy as mine) record on the card mode (which on mine drops the framerate down, pixelizes it,etc). Or just record at a lower shutter speed.
Or using your editing software go into your effects tab and take a look at the color effects. Photo filter, color balance, color hue, etc. And I'm sure it has some great pixelization presets as well as noise/gain. Then export that at a lower framerate (15fps?).
