All theoretical. One would have to assume that space was the problem for any faults in the first place.

Not always the case, but true for the most part.

I am under the opinion that these are going to be EXACTLY the same as the transfers available now with new branding to suggest that based on their source files they look great upscaled on Sony 4K displays, nothing more nothing less. I would LOVE to be proved wrong on this by the way.

And so it shall still be.

Given the same compression parameters, higher bitrate will yield better quality quite non-theoretically. Whether the improvement can be seen without pixel-peeping is another question, since Sony tends to do a pretty good job with their encodes. For bandwidth-intensive material like, say, Taxi Driver with all its grain, going from ~23mbps to 40mbps or whatever the limit is, everything else equal, would certainly yield some degree of perceivable difference.

That second article makes it sound like it just uses different formulas and equations to get a 15% better result at best. I'm not gonna spend what I could get a new car for on 15% better color that I probably can't even tell is better without direct comparison. Of course, I could be reading it all wrong.

Grain of salt. For one trying to do an encode of a feature length movie in xvycc would entail a MASSIVE amount of compression. The reason movies are 4:2:0 YCbCr isn't because higher color depth isn't available, it is because of compression and space. Sony hasn't magically come up with a new standard for compression and added it to the Blu-ray spec, the process they are talking about has to do with the mastering side and they've been doing it for a few years already. Now they could try to push the fact that their BD players and TVs can do deep color output, but that would be nothing new since that has been around on just about every brand from the beginning. But there is no way these discs are encoded in a wider and higher bit depth colorspace. Again, the BD spec for video won't allow it.

Now the only piece of information is whether the original Ghostbusters BD was sourced from a 4K transfer or a 2K, and whether or not that is any different than what we are seeing later this year.

Colour depth (Deep Colour) has nothing to do with extended gamut (xvYCC) as its still 8-bit. You are correct in saying Blu-ray's are encoded with YCbCr 4:2:0 8-bit, but xvYCC just makes use of the footroom/headroom to use for the extended gamut, thus all devices need to support it.

I am no expert, so it would be nice to have some proper clarification on all this. As from that quote of the special features, 'expanded colour' is asterisks with the note being, "Expanded color requires xvYCC-compatible TV and Blu-ray player". Perhaps its just a ploy to get people to buy kit marked with x.v colour.

Edit:

H.264/MPEG-4 Part 10 version 6 allows for extended gamut, and HDMI 1.3 and above provides a mechanism to negotiate if a display supports it, and the range that it can support.

If you want to get the crowds to come around
You've gotta have glorious Sonycolor,

I have a 4K Blu-ray player but will it show 4K on my TV since it is not 4K?

[Metallix87]

So, basically, from what I'm gathering, there's a chance that the Ghostbusters 4K Blu-Ray will be a noticeable improvement over the current release, but also a chance it'll be more or less the same in terms of visuals?

Awesome. Well, I guess I'm still taking the plunge, but if I end up getting burned, I doubt I'll go for any more of these 4K Blu-Rays in the future.

I think it would be best to hear some reviews of the 4K Blu-rays before double dipping on them

Technically, it would be my first time dipping, since I got the previous Ghostbusters Blu-Ray as a birthday gift a few years back. That Blu-Ray was okay, don't get me wrong, but it definitely left a lot of room for improvement in the visual department.

If people can notice the PQ difference between a DVD and Blu-ray on a CRT set, then you should be fine.

[HuggyBear73]

I'll take a chance with GHOSTBUSTERS and GLORY I guess.

Regarding Ghostbusters. The picture quality isn't the problem on the current Blu, it has fantastic detail. It's the heavy contrast boosting that's the problem. I have a hunch that Sony will sort this problem out on the new release, seeing as they tried to fix it as much as possible on the current Blu. The damage was already done though, so the only way that Sony can fix it, is by rescanning the film from scratch.

As you can see in this screenshot, it's not as blown out as the DVD but it's still far too bright. There's some serious highlight clipping going on in that scene.

Fingers crossed that the new transfer fixed this problem.

It'll undoubtedly be an improvement, but it might not look as good as you might expect, just by virtue of how the film was photographed.
That doesn't mean other 4K remasters won't look fantastic, it all depends on what material they have to work with.

As long as it's an improvement, and fixes the contrast issues, I'll have faith in this 4K Remaster line.

And so it begins. This is exactly like when upconverting DVD players boasted 1080p outputs and people thought that meant they were watching HDTV.

These Blu-rays have no more resolution than what they had before. They are still 1080p24. Sony is saying that they are from new 4K masters (doubt it) and have expanded color gamuts (extremely doubt it). They are also claiming that they are primed for upconversion to 4K for their new 4K displays.

So if your Blu-ray player can upconvert to 4K or you have a 4K display it will simply scale the 1080p movie to 4K (which it could do with ANY Blu-ray out there). If you have a 1080p display you are going to watch it in 1080p just like you would any other Blu-ray. If a new 4K scan was indeed done there is a chance you will see an improvement in detail even with 1080p playback. Most of the titles mentioned were already mastered from a 4K source the first time they were released on Blu-ray (Taxi Driver, Spiderman, Total Recall, etc).

No, you don't have a 4K player since the current Blu-ray format is limited to 1080p.

Your machine might be able to upscale to 4K, but since your TV is not 4K anyway, you're not getting 4K anything.
