He says the father worked for Kodak and took a new test video recorder to the game.........
It would have been a film camera. Probably a cine-Kodak model b with a spring drive, which came out in 1925. The earlier ones were hand cranked and would have required a tripod to get a steady picture. Maybe a model BB which was new in 29 and took larger reels.
Video recorders were essentially nonexistent in 1929. Baird in England was recording some early television on records, but the equipment was far from portable. And the first commercially available video recorder wasn't sold until 1956. And it was huge.
Not the most credible story.
