[QuadList] Mechanical Splices

Yes and no

I started on quad in 1972, big jump from the VR7800 my previous employer
used

I only ever worked on Hi band and in colour sorry color 

Physical edits were 4 field, and almost disappeared, but now and again, did
pop up as a solution to a problem

(A  USA Drama required timed holes to insert commercials, I made them 2
seconds too long , the tape came back so I physically cut two seconds out of
each black hole I hope the inset edited commercial worked) 

 

E-E edits well they were originally 4 field, but we had a crude edit
controller and one of the guys used to use Tape Speed Overide

To sync up some editing, OK if you sync up the Play in Machine it’s in
Pixlock

But if you sync up the recorder it’s in switch lock and will 2 field lock
after initial lock

So he made 2 field edits, on TR70’s the NSTD PAL light comes on

To indicate you are 2 field out from station sync, but it’s OK you if don’t
let presentation mix off or its blue faces.

 

Eventually he made tapes that went to ABC Australia and AVR2’s sort the non
standard PAL out ie they reframe

So they all came back for me to sort

 

4 field edits work but jump ¼ cycle of sub carrier at the edit,  not bad if
its scene change

But if it’s an invisible edit for a camera trick you are in trouble

 

Remember when PAL was invented everyone thought it was a 4 field sequence.
It was much later

That it was identified as an 8 field sequence and the rule book had to be re
written to identify the difference between field 4 and field 8

Trevor,

 

I was about to ask about splicing in an eight filed sequence. You beat me
too it! But since colour (PAL) was not adopted till 1967 in the UK, weren't
most edits E-E by that time, except for some emergencies? And in High Band?

Yes we only had the Ediview solution to see the tracks, There was later kit
that displayed the control track on a scope tube, but I never got my hands
on one,

being a PAL county you had to get the 4 frame sequence correct or there were
blue faces.

Also needed to record tack phase correctly if you wanted to join one tape to
another, or you lost or gained lines at the edit and it would roll over.

 

Whenever the edit did not work and had to be remade earlier ( even in
electronic days) they expression “working your way back to the lineup” was
coined ie the bars at the head

I still use the expression today when something goes wrong and you need to
dig further, often fixing the car
