I just went to goodwill bought a projector and set up a little screen with
a and black frame and used a nice modern video camera to film the movie
being projected. It's actually very easy to do. Take the time to get
the lighting right. Tip - Project closely to the screen, the smaller the
projection the better the resolution.
Why?
if you want the best image, then use a relatively low wattage projection
bulb, remove the projector lens, and mount the camera to focus right on
the filmgate, if you have a suitable camera that can close focus for that
size.
