Just as an fyi, that's pretty massive tape used in a broadcast studio.
The first consumer video camera (camera that recorded to tape rather than film) wasn't until the BetaMovie in 1983 with VHS coming months later. Heck, _home_ video recorders were still 15-20 years off at the time.

Obviously "video" existed then in the sense that there was television -- but consumer video cameras didn't appear until around 1979 or 1980.
