I think someone has confused window-box (black bars on four sides) and pillar-box (black bars on left & right sides).
I'm curious. Both of these are taken from the same master. How does one explain a >8 GB difference in file size? That's roughly a 25% difference. The Criterion is clearly contrast boosted. Why would they compress the file also?dadaistnun wrote:Beaver comparison is up.
The bum's right eyelid is the only slight indication in my mind that the still is not the same; however, that doesn't account for such a large discrepancy of information IMO.Kirkinson wrote:The review lays out the contrast differences really well, and Criterion's black levels do seem a bit excessive, though on its own terms the image is still quite superb. What I'm wondering about now is the difference in framing on the last screen grab, the one where the blind man is grabbing Peter Lorre's shoulder. The Criterion disc has more information on the left side of the frame and less on the right, compared to MoC. To me, this is much more curious than the differing bit rates if these indeed came from the same master.
EDIT: Looking at it again, I'm not sure those stills were both grabbed from exactly the same moment (Peter Lorre's head seems to be at a slightly different angle) so that probably accounts for the little difference in framing.
Strike two, then. Contrasting boosting to give an ersatz sense of depth at the cost of image detail and sacrificing bit rate to cram all the extras on one disc when a second SD disc would have done fine for most of the extras. The MoC looks very much like a 1930 B&W film. The CC returns us to the earlier discussion of a more modern, noirish look. To be sure, the CC appears to be better than any other choice, save the MoC, and I suppose it had to differentiate itself in some way from the earlier BD release, still...Kirkinson wrote:The most likely answer is that Criterion used a lower bit rate because their extras take up more room, which would seem to be supported by the fact that their total file size (including extras) fills the disc to the brim, while MoC have a few gigs to spare.
I know we're talking about the Blu Ray versions (and I haven't jumped into that lake yet), but will this make a visual difference depending on the size of the screen one is using to watch? I would assume that a loss in image detail would likely be much more noticeable if one is watching over a very big screen. Does that make any sense?triodelover wrote: Contrasting boosting to give an ersatz sense of depth at the cost of image detail and sacrificing bit rate to cram all the extras on one disc when a second SD disc would have done fine for most of the extras.

If you look at the screen grabs at Beaver, you can see the deeper blacks have cost some detail that's particularly noticeable in things like the fabric of clothing (the children on the periphery in the first grab, Lorre's topcoat, the trousers in the next-to-last set of grabs). I know things like that are noticeable on my 50" display, but I believe I would have noticed on my old Sony 32" CRT (c.1999 model) also. I'm less certain about how the file compression would manifest itself on various-sized displays. I know it's a different thing, but if you compare a 1080p BD disc with the results of ripping that disc with a program like MakeMKV, the resulting file is some 30% to 40% smaller and there is some loss of resolution as a result. How large the display has to be before that becomes intrusively noticeable I can't say because I have no way to compare BD on different types and sizes of displays, but I should think it would depend in part on what was being filmed.Tribe wrote:I know we're talking about the Blu Ray versions (and I haven't jumped into that lake yet), but will this make a visual difference depending on the size of the screen one is using to watch?

Because we have information that the MoC has not been manipulated at all and that the Criterion has. Of course, this isn't the end of the argument, as Criterion would presumably claim that their manipulation was done in order to make the raw transfer truer to the way the film originally appeared.Brian C wrote:Pardon my ignorance here, but how do we know that the CC has been manipulated to appear darker, and not that the MoC has been manipulated to appear brighter?
Completely opposite reaction from me. CC's image looks like it's been pulled towards a generic 50s film noir look.aox wrote:Tough call, but I give Criterion the edge here. I like the inky blacks and the "deeper" more three-dimensional picture. For right or wrong, the MOC looks flat and two-dimensional to me.
There are oddball exceptions to every rule of course, so I don't want to make this sound ironclad, but as a general rule: you cannot, through manipulation of the black/shadow palette, pull details (i e fabric patterns) out of areas that were photographed in deep shadow... i e you can't create details that were not there in the first place; but you can mask details that were there originally by the digital amping up of the black/shadow palette. Try it yourself in photoshop.Brian C wrote:Pardon my ignorance here, but how do we know that the CC has been manipulated to appear darker, and not that the MoC has been manipulated to appear brighter?
You'd notice this sort of difference on any size of screen really. I mean you can immediately see the difference between the two transfers by looking at the compressed screencaps on Beaver without even opening them up to their native resolution.triodelover wrote:If you look at the screen grabs at Beaver, you can see the deeper blacks have cost some detail that's particularly noticeable in things like the fabric of clothing (the children on the periphery in the first grab, Lorre's topcoat, the trousers in the next-to-last set of grabs).

Actually we do have a way to know. From the MoC M thread:zitherstrings wrote:What is the source for this print? Because there's no way (for us) to know that MOC isn't working from something that wasn't properly treated. Perhaps they have the pure copy out of the telecine but that's not accurate to the actual film?
The quote is from Nick Wrigley, who is one of the principals at MoC and co-producer of the disc.peerpee wrote:We didn't do any additional restoration on the HD master, other than refusing to use grain removal or other filter software in the AVC encoding stage. The HD master was pretty lovely and clean.
I agree of course and for this reason prefer the MoC because if I wanted to boost the contrast I could do so on my own projector where as I couldn't undo the boosting that Criterion appear to have done.HerrSchreck wrote:you can't create details that were not there in the first place; but you can mask details that were there originally by the digital amping up of the black/shadow palette.

I'm not sure anyone is saying that lighter with more detail is always preferred. This is a 1931 film, and the film stocks of the time just couldn't achieve the level of contrast available later (like in 1987). To boost contrast and deepen blacks creates an unnatural appearance that wouldn't accurately represent the original (while also obscuring detail). It's like recording a jazz quartet and over-miking the bass. Some folks may like "feeling" the bass, but it's not what the music sounded like acoustically in the recording venue. Jonathan S is correct. If you want that effect you either have or can add controls to your home system to achieve that. The producers of the disc - BD, DVD or CD - shouldn't be making that decision for you.swo17 wrote:Just to play devil's advocate for a moment, is lighter with more detail always preferred? See the debate in the Sous le soleil de satan thread.
Now I'm confused. I understand the issues held by some regarding the boosting of contrast and the deepening of black tones...but why exactly are we leaping to the conclusion that there isn't an accurate representation of the original...without anyone around to have actually seen the original...or some other evidence? Some may find the practices objectionable...but stretching that to the conclusion that the movie wasn't "intended" to be shown that way or that its somehow not faithful to the original seems to entail a number of assumptions that "aren't in the record" (OK, OK, I'm preparing for hearing...).triodelover wrote: This is a 1931 film, and the film stocks of the time just couldn't achieve the level of contrast available later (like in 1987).

In addition to what has been noted regarding details in dark areas which have been obliterated by darkening on the CC disc, note the lighter areas, such as the close-up on Lorre's hand (I think it's Lorre's) going into his pocket. The very light shadows, such as from the knuckle, are lighter on the MOC than on the CC, but they have not disappeared as they would have had the image been overly lightened.Brian C wrote:Pardon my ignorance here, but how do we know that the CC has been manipulated to appear darker, and not that the MoC has been manipulated to appear brighter?
