I like your point that it’s “film.” From all I’ve seen, both sides shot photographic film and there’s no indication that either used any video tape, practical video tape being an invention that was to come in the 1950s. Indeed, all of the color pictures of Kennedy and his assassination that I’ve seen are film, not video tape. Really good color video that can compete with film is only a fairly recent invention.
Turning to colorization, some of these films look like they were colorized. However, pre WWII Germany had the world’s finest photographic industry, an industry that developed and produced a great deal of practical color film before any other country’s. If you’re as fascinated by pre WWII pictures of Germany and Hitler as i am, you will come across many good movies and stills in color. Thus, I suspect that many of the really good looking clips from these two films were genuine color and not colorized.
People mixing the terms video and film drives me crazy.
I’ve worked with 60s era 2 inch quadarplex machines and to get a playback with good tape stock took about 30 minutes or so including scraping the tapes, usually twice. That doesn’t count the 24 hour warmup period I did which helped immensely.
The quad needed compressed air so the air bearing that the heads were on would spin. Air was the only way that a video head system would turn fast enough.

They were on the cutting edge of audio recording as well. They pioneered magnetic tape.
