Actually, way back then motion cameras were very expensive and rarely were they home owned. My uncle had one, he had to send the film out to be made into a reel. and he put them into a projector , to show on a screen.
By the time our grandkids started to arrived 21 yrs ago, home movies were much easier. We did take a lot of the grandkids.
