I saw Leon Redbone open for George Carlin at Ceasar's Tahoe back  
in... uh, when I had hair. I enjoyed Redbone more than Carlin.

Nice transfer and tweaking, Park.

I see some artifacts that are the result of film to video.  The CBS  
Sports Spectacular open is on film, and the sponsor credits looked  
like 2 x 2 slides keyed in.

If you step through the title change, you'll notice it's not a direct  
cut... it has a bit of motion and field ghost that looks to me like  
the "wipe" to the right from a multiplexer or slide projector mirror  
flip.

The clip that follows the Redbone performance is also film... easily  
seen when the organist does the bass to treble run up the keyboard,  
and you can see the 3:2 pulldown easily.

The pulldown on Green Acres has already been mentioned. The telecine  
system used seems to have a green ghost (reg error? Optical problem?)  
visible in to the right of Oliver's right shirt sleeve.

Somewhat like the optical ghosting someone pointed out last year in  
the RCA-TK41 that shot the so-called "Kitchen Debate" with Nixon and  
Nikita 50 years ago last Friday (July 24).

Apparently the dichroic mirror system didn't like being hit with  
bright images.

See separate post about the Kitchen Debate tape.
