First I'll preface my comments with the fact that I'm watching this on my Laptop's LCD screen which is most certainly not properly calibrated for video. I've tried to keep this in consideration when watching so I hope my observations help.
So, I've watched the first 8 1/2 minutes (everything up to the point we leave the Tantive IV for good).
My first reaction has to be... The crushed blacks! Where did they go!? I'm totally amazed at what's been accomplished here! I realize that my laptop screen is not accurately displaying brightness, black levels, etc. But there's no way that's enough to explain away what I'm seeing. You've pulled detail out of the shadows that I thought was gone forever in this transfer. I really wish I could put this up on my tv & see how it looks there, but I'm not that tech savvy... Anyway, it's so nice to no longer feel like I'm staring into a black hole when they do a closup on Vader's helmet!
Regarding the colors, I must say that the explosions and flashes look SO much better now. No more neon pink glare! However, for the rest of the colors, I felt like they might be toned down a little too much. It's subtle, but I feel like the over all color saturation could use a small boost. And, I realize my next comment is treading on very dangerous territory (especially when considering my comments about the flashes & explosions) but I think the reds in particular have been toned down too much. Keep in mind this is VERY slight. But I do think a slight increase in red saturation could help. But again, VERY slight.
Anyway, I need to keep watching but I'm loving what I've seen so far. I think what you guys (I'm assuming you_too helped) acheived with pulling more detail out of the crushed blacks is just blowing me away.
