Yeah, this doesn't look like AI generated. It was probably filmed on super 8 film stock. The clothing, hair cuts, manufacturing process all scream early 80s.
I could see a cheap restoration introduction artifacts as a more likely reason for the look.
It looks more like video to me, honestly. It appears to be a smooth 30fps rather than the 18fps I'd expect from Super 8. There are also telltale stair-stepped sloped lines that demonstrate the effect of the deinterlacing. There did exist luggable 3/4" U-Matic recorders which I'd have to imagine CBS would have been using in 1980.
