That speed wasn't possible with any color processes in use at the time.

They could do three separate reels of film, RGB, or maybe YUV. YUV might be an easier choice, as slight mismatches in image alignment would be less serious. As U and V are about half the resolution of Y (B&W). The TV station would need 2 extra telecine machines, and feed their outputs to an NTSC encoder set up to use YUV. That's starting to sound too expensive for the day, though...
