You mean record to a video cassette tape or to a 1” reel to reel video tape?
Video cassettes that fit into a video camera were not invented as of Apollo 17.
Huge 3/4” video cassettes (they are like ten inches long, three inches in depth and six inches wide) were invented around 1970, but they were used strictly in huge recording machines in TV studios, not in the camera itself.
The point is, video cameras c.1970 were not battery powered.
It was film. You need a projector to watch it. I don’t know how it worked exactly but these are home movies made in the 1960’s using a small video recorder. If I’m lying then I must be part of a NASA conspiracy. They’re not paying me enough, though.
