[QuadList] Mechanical Splices

[Trevor Brown]

Having made physical splices on quad tapes, you tend to be pleased if they
play without frame rolls, yes the sound edit is about half a second after
the video edit, and in theory  it could  to be cured by an L splice, but
then the top of the L would be 9" long,. (for a sound and picture cut in the
same place)

So I think the L splice is a concept that,  but would not in practice have
been carried out by a physical  L cut in the tape, which would be almost
impossible to perform, and would be rather hard on the head wheel which
would scan across the top of  L,  getting on for 500 head passes, ( could be
expensive in terms of head ware)

 

I suspect buy some sort of audio lift, or parallel audio recording although
the dates you quote are very early for anything along these lines

David,

Thanks for your reply.

A little more background on my question:

My dad, (who worked at CBS 1949-1973, but not in tape) remembers hearing of
a 1962 musical show edited with an "L Splice" which was a mechanical cut to
include the audio track. This seems to be quite a feat, yet it has been
verified by a friend of his who also has memories of such an edit. The
editor mentioned might have been a George Hartmann?. This is all I know.
Quite a feat and really tough on the headwheel!!

Regards,
Harold

Harold,  

 

I have not heard of this from a standpoint of physically splicing the tape
in a non-straight form. What this "L" cut may be referring to is the
practice of cutting the picture and conforming a separate mag or audio tape
to have the audio cuts be in-sync with the picture cut. Such a system was in
place in the 50's and 60's at NBC Burbank. Having laughs cross the edits
also helped in the separate system approach, such as in Laugh-In. On the Cyd
Charisse (1959 color) presentation, such a system of post pix edit audio
conform was used throughout the program, but was especially critical in the
first dance scene, which was heavily spliced. The music track that Cyd
danced to was consistent and uninterrupted by the physical cuts.

Hi all,

I would like to access the experience of the list. I have heard of an "L
Splice" which was said to compensate for the separation between the video
drum and audio stack on a quad machine. This seems quite amazing to me and I
wonder if anyone else has heard of this?

Thanks,
Harold
