"This was done in 1953 because RCA was overly concerned about the
appearance of a 920 kHz beat pattern in pictures on early, pre-color B&W
TV sets. Not a color set problem, a B&W set problem!
"Editing, timecode and standards conversion would have been much easier
if the color subcarrier frequency had been left at its initial frequency
of 3.583125 mHz because H would still be 15,750 and V would still be 60."
It amazes me that we can't get to 60 hz with the current state of
technology. I tried to get there when we built our new facility from the
ground up. It didn't work out. Most of the equipment can handle 60 HZ but
there were two critical pieces that we could not get to work at that rate.
So, we dialed everything back to 59.94 and we're stuck there today.
