larryi,
Back in the late 70's early 80's when I was working in a studio we would have to run second generation masters. The mixed down master was almost always done at 15ips. To save time, we would take the 15ips tape and then play it back at 30ips. The machine making the recording was also running at 30ips. Honestly, there was no loss of information whatsoever. We did this regularly using either Scully's or Ampex machines.
I am pretty certain that many of those companies making second generation masters are doing the exact same thing as we did. Running and recording at 30 and playing back at 15.
This would certainly be necessary to play into the economics of mass producing second generation master tapes. I don't know of any machine capable of 30ips that is less than stellar in performance.
Studer, Sony, MCI, Telefunken, Scully, Ampex were all common place in various studios and dubbing banks.
When we think about the cost of two metal reels, tape, packaging, and the labor to record and package the item, $450.00 is still a bit on the high side. If they could cut that cost to just under $200.00 per title, I think they would have a hard time keeping them on the shelf.
We should also consider some master dubs at 7.5 ips I have heard some of these and I must say in most instances that I absolutely cannot tell the difference between a 15ips half track and it's 7.5ips half track copy. If we were talking quarter track then it would be very obvious, but half track is a different story. Just think what that would do to the cost of second generation masters?
