I thought it time for a bit more background.
I've now spent some additional quality time with the Blu-ray of It's a Wonderful Life, and I can see why a number of people like it.
It's clean. It has a wonderful contrast level and a terrific gray scale.
But the more closely I look, the less I like it, and here is my reasoning.
There is a simple purity to film.
Going back 105 years the motion picture film base, be it nitrate, acetate or paper, has been a device that holds grain, which is the source of an image.
When the film is run through an appropriate device, we get "movies" or "flickers."
In its purest form, the image is controlled by the grain.
As film is duped (and this is era dependent) we get added softness, sometimes objectionable grain and a myriad of analogue artifacts -- some from the dupes, others caused by processing problems.
When a film is prepared for standard definition DVD, grain has a problem for proper compression, and the grain "problem" has been affected in various ways. In the most simplistic form, the entire image is slightly softened and then edges are sharpened to provide a less grainy image, but with a perception of sharpness.
One of the wonderful attributes of the Blu-ray system is its ability to reproduce film as it would be viewed projected in a theater -- grain and all. If there are multi-generational offending dupes, damage or other problems, these can all be attended to in the digital realm, and without any damage to the image quality.
However...
And this is a huge however, and in this case the 800 pound gorilla in the room...
When one has a film element that is not problematic, or with only occasional problems, it is relatively simple to reproduce as it is without a great measure of digital image management or "enhancement."
If one wishes to change that image for whatever reason, and if that reason is to lessen the grain structure, one may move in one of three directions -- and I'm being simplistic here. Throw the image slightly out of focus, use a higher degree of digital functionality and go the spatial route, or move in a temporal direction.
What appears to have occurred with It's a Wonderful Life is that it has been through the digital ringer.
It appears that grain has been removed, and the image may be slightly artificially sharpened, but whatever vendor did the work was not able to handle the tools they set in motion. Digital work generally functions in blocks. Computers determine what they're seeing or are told to see in blocks of different sizes. The smaller the block, the more processing power necessary, and obviously the higher cost of processing in a monetary sense.
The main problem that I'm having with It's a Wonderful Life is that I don't believe, with extremely high quality film elements in hand, that it needed any of this processing.
And it is the processing, and controlling the image that came out the other side which must have gone through at least two levels of QC, that I'm finding highly offensive because of the total loss of a film-like image. There is absolutely no reason that when Mr. Stewart or others walk across the frame, that because of poor processing, that the blocks of pixels mentioned above are unable to determine what is Mr. Stewart's head...
and what is wall.
Bringing It's a Wonderful Life to Blu-ray should have been an extremely easy affair, and someone, somewhere has complicated it to a point where it is no longer a film, but rather a digital image masquerading as film.
What might have been something beautiful, reproducing the look of this wonderful film, is simply not what it should or could have been.
And this is not about budget.
Properly scanning and down-rezzing these elements should have been far simpler than what has been done, and I would bet, at a lower price.
I'm not saying that people cannot enjoy this Blu-ray, either in B & W or colorized.
My point is very simple. That those who wish to own It's a Wonderful Life on Blu-ray should be able to add the disc to their collection, and that disc should live up to the dynamic capabilities of the Blu-ray system. Those with smaller image environments should be able to enjoy it today without considering what it might someday look like on a screen ten feet high by eighteen feet wide.
This Blu-ray has a troubled image, created not out of technical necessity, but for other reasons that I cannot fathom.
And that is why I'm suggesting that the work be performed again, in a simpler and more direct way, toward the creation of what can easily be a perfect Blu-ray disc.
