[QuadList] Chris Hill's old favorite TBC--

[W4wj at aol.com]

Years before TBC's hit the ground running, WLTV in Miami  would
feed the video from their Akai 1/2" R-R B&W  portable videotape
machine into their "Winchester Cathedral Video Converter" to  air.
 
The Converter: A B&W monitor, in a black box with a large  viewing hood,
with just enough of an opening for a GE PE-250  to take the shot!!
 
Crude but cheap, and the "first" ENG tape on the air in  Miami!!

There is the old favorite TBC that is all  forgiving and allows for unique 
control.  It is the most beautiful  system ever devised.  Requires the use 
of two pieces of equipment and  some care.
 
Take an under scanned black and white monitor  and shoot it with a camera.  
Then you have all sorts of control via  knobs on the monitor and the 
camera.  The monitor acts as a beautiful  sponge.  If you have a fast time 
constant in the monitor, then you do  not see any flagging.  Use a dark room to get 
rid of reflections.
 
I have done that in the past and it  works.

Same idea behind the slow-scan to NTSC frame rate converter for the moon  
shots, with an added disc recorder to repeat frames as needed.


I used the same "shoot a monitor" technique when working in a 3/4" suite  
that lacked a second TBC for A-B roll.


We had some color composite Commodore computer monitors that we used for  
general purposes around the facility. No underscan, but had good pictures for 
 video or computer signals.


I put one of those in a dark room, put tape over the camera tally light  
and with bars on the screen adjusted framing, zoom and focus as needed to get  
the image size needed with minimum Moiré.  


With a properly chipped 3-Saticon camera, I found that I usually needed  to 
reduce the brightness, contrast and saturation on the monitor but got a  
very nice picture I could shade from the CCU if needed. 


Like horror movie SFX, it worked well if you didn't keep full-screen  stuff 
up longer than needed to get through the transition and to the next cut.  
Picture-in-picture shots worked better, and I'd put the monitor in a box  
wipe to eliminate any curved edges of the monitor.


Ah, the olden days when chewing gum and bailing wire were still  useable.
