If you have a cd writer, a dvd player that can play vcd's, and a video recorder, you could put a low res copy of the 3d clip in mpeg format on cd (PAL is usually 640 by 480 pixels but I would do less). Hook up a scart cable from the back of the dvd player to the video recorder. Record from cd to vhs (the older the tape the better, if you want lots of "noise"). Then just capture the footage back to the computer the way you did with the original footage. It's a long way round but maybe the best way of doing it without using video editing software. Black and white is alot easier to age and match in, colour is surprisingly hard.
