I picked up both of the above used, and pretty much agree with NJPete's assessment.
is the best. And it is a huge
improvement over the Mill Creek DVD. Detail, grain color and contrast are all very good, for the most part. Blacks appear a tad elevated at times, and the whites are clipped about as low as I'd go on something like this. A little detail is lost in white shirts and the highlights on people's faces. But it's not bad. And the upside is that the image has lots of depth and contrast, and should look pretty good on both lower-contrast IPS LED displays, and higher contrast plasma, OLED, and VA LEDs.
I lowered the Backlight a bit on my VA LED, because the image was so bright and contrasty. That makes the blacks even deeper though (which is a good thing in my book). And I also darkened both the Brightness/black level and Gamma just a hair, to compensate for the slightly elevated blacks, and extra brightness in the midtones.
The Curse of the Mummy's Tomb
is also a pretty substantial upgrade from the DVD. Some evidence of compression is visible, but the detail is much better for the most part. And there is a medium-fine grain to the image, and much less (but still some) ringing. Contrast is on the high side, and the color tends to favor browns and blues. Yellows and golds look a little too orange, I think. But the color palette is still pretty rich and diverse in many scenes. Blacks are a little inconsistent, but slightly elevated for the most part imo. The image quality isn't as good as The Gorgon
. But it's better than I expected for a budget release, and certainly the best that I've every seen this film look.
The Two Faces of Dr. Jekyll
is also a step up from the DVD, both in sound and image. There is fine detail and grain in the image, but it's a little "mushy" for my taste. I did raise Sharpness a bit to compensate, but that enhances some ringing in the image as well. So there are some tradeoffs. The color and contrast are pretty good. This film is loaded with beautifully-dressed, exquisitely lit sets, costumes and art direction. And you definitely get a little better feel for all that "Hammer glamour" in this HD edition (though there is still some room left for improvement, esp. in the detail dept.).
I made only small adjustments to both the Brightness and Gamma to compensate for slightly elevated blacks, and to give the gowns and sets a little more richness and depth. I also made a small adjustment to the aspect ratio to compensate for a little horizontal stretching in the image. The slight mushiness in the detail makes me think that this could've been sourced from an analog tape master. Not sure about that though.
I haven't given Revenge of Frankenstein
a very close look yet, but it looks like this was sourced from a rather grungy print, as NJPete said, with some scratches and fair amount of dirt (white specks). And I also noticed some "smeariness" in the detail in the midtones, which could be an artifact of compression.
I'll post more thoughts on all the above after I've watched all four films in their entirety. I'm not displeased with my investment though, so far. A couple of these films appear to be in as good or possibly even better condition than some of the films in the Universal 8-film set.
