The time-delay kinescope recordings were made with separate sound tape, I believe, which would explain the sound quality. This film, however is very odd. It obviously originated on a kinescope recorder of some type, as evidenced by the lack of shutter bars. Notice also the somewhat poor vertical linearity. The question then becomes one of what type of kinescope.
1) A lenticular recording, later transferred to Eastman color?
1a) This program date may be after lenticular recording was stopped - have to find the dates when it was used
2) An experimental recording from a color kinescope? Note the round image borders as well as the vertical linearity problem. One would expect a non-experimental kinescope recorder to have nearly perfect linearity by this time.
Note that the known Ernie Kovacs lenticular film does not have a round mask, and the quality looks much poorer than the Perry Como film.

2a) maybe a color video tape, later transferred via a color kinescope recording experiment?
