RACKING |

|
A film is "out-of-rack" when the image appears slightly too far up or
down, showing part of the black rack bar at top or bottom.

The sound on the 35mm comopt prints we got from NBC had a wide
dynamic range which Presentation upstairs in CCR at AP didn't like, so
we took it in turns, one of us standing by the Cintel scanner watching
the soundtrack on the film as it came off the top spool (thus giving us
a couple of seconds before that part of the soundtrack arrived at the
soundhead). It was easy to see the modulation on the track, so we would
shout "loud music" when we saw high modulation coming, and whoever was
sitting at the control console would fade down the sound a bit,
bringing it up again for the narration which had been recorded at a
lower level than the music.
(Rack) King for a day! Film programmes such as this used lots
of archive newsreel footage and often the pictures would be "out of
rack" to varying extents. On the rehearsal (all films were rehearsed
before transmission) one of us would be designated "Rack King" for the
showing and so at times it was my duty to stand beside whichever Cintel
scanner was on air, with my hand on the racking knob attempting to
correct for out-of-rack sequences as soon as they appeared on screen.
One day when showing a film which included shots from a wartime
newsreel, Tony Cheale noticed some vertical streaking when people in
the shot moved left to right etc. Horizontal streaking can occur in a
television picture due to a fault in the system and the fact that a tv
picture is scanned horizontally, but he wondered what could cause
vertical streaking.
At the time I couldn't answer but subsequently found out that
it was due to "developer fatigue" when the original negative had been
processed. In wartime, chemicals were in short supply and so film
developers were used to their maximum and not replenished so
frequently.
