BDgeek was nice enough to provided me with a couple of different soundtrack versions. Creating an isolated score is hard enough but after reading this I'm having even more doubts about being able to get something together. I won't know more till I listen and see what I have to work with.
For some strange reason Blade Runner is much, much easier to grade then Alien. So, in sitting around I have test graded a fare amount. Some shots I like better, some worse:
BD/BD regraded to LD
I really like these, especially the last one at the bottom. This looks exactly like the timing on the 80's VHS I have, which is most likely from the same transfer as the LD you are using. The VHS has those reel change markers too. That last shot at the bottom though is one of the things I've always noticed that looked radically different in any other transfer I've seen other than the VHS.
I've never seen anything other than the Final Cut in theaters, but to me the VHS look seems the most natural looking. The Director's Cut DVD also has radically different colors than the BD, but I think it's been established that the colors in that transfer were over-exaggerated.
