We projected our films onto a screen and just filmed the image with a camcorder on a tripod. We also had a some tacky (Hovis) music playing in the background. The soundtrack includes sounds of people moving around, lots of "shhhhhhhhing," the phone ringing, rude comments and laughter.
The quality is awful, but they were just ancient "family on the beach" films.
The results are amongst our most treasured posessions.
