Cinescopes or something like that, maybe, but the existence of videotapes from the early Sixties may be a bit doubtful. I did a television series on my local eductional station in 1959 and we had to do it live. Of all the TV stations in Seattle, only one, THE major station in town, had a videotape machine. At the time, they were about the size of a wardrobe and the reels looked like reels of 35 mm. movie film. Brand new technology, the machines cost over $50,000, and at that time, that was a lot of money. It was into the mid-Sixties before the other stations got them. Home units like Beta and VHS didn't come out until many years later. So it doesn't seem to hopeful.
