I can understand that you have a hard time believing Paramount would not invest in their biggest franchise, and also understand Jeff, when he believes the information he was given by his studio contacts that all masters were made anew from 35mm elements. I am sure that many outside the loop would feel the same way. After all, it makes all the sense in the world to invest in order to milk their biggest cash cow, right ? Yeah, well, maybe not so much. While STAR TREK was always front and center when it came to making money, when it came to investing money in to the materials the story is very, very different. Ask your contacts, Jeff. They will tell you

. This (to me) is about facts similar as you would find them coming from a professional QC - nothing more, but also nothing less. And here I can tell you (as both of you [as well as Bill] stated, none of you have seen any of these masters or the discs) that a lot of what you hold to be true, be it by simple belief or by what you have been told, does not add up with what I see on these Blu-ray discs - not by a long shot.
I checked through the discs and compared also the framing on several reference setups (QC monitors and screen, etc) here and, as I said, everything - on all discs/masters - points to at the very least a very poor cleanup and mastering involving major use of, partly beyond tolerance level, de-graining and de-noising tools that not only effected but degraded the image in some cases [IV, VI as well as II, for different reasons] severely. Now, in two cases (IV and VI) several indicators such as video noise stemming from a tube telecine now extremely rarely used for HD mastering, especially in the U.S. as well as identical framing (without an exact "frame of reference", pardon the pun, duplicating that is a lucky shot) and equally identical picture instabilities raise very much the suspicion that an older master was the actual prime source rather than a 35mm element. Further indications are that at the very least in one case (VI) a native interlaced 59.94i 1080 signal found its way into the mastering chain to BD, something that does not make any sense whatsoever.
Now, let's just say for the sake of argument that all masters
are new. This, on the other hand, would open up an entirely new can of worms. Because, it would mean (and I don't know how else to say this) that the people entrusted with this task were simply extremely clumsy at their job despite having had access to all materials. And, Penton, that is what I would find hard to forgive. There is no excuse for this, all technical possibilities are there, the potential is there. I know Paramount can do an excellent job. They have proven it. But, without a shred of doubt, this Boxed set is not one of them. Not on any of the 6 movies.
