Well, seeing how wrong I was when I defended the honour of the 3D performance of the 55" 4K set (it's only 540p, not 1080p as assumed!), all I can say is that even a broken clock is right at some point during the day. biggrin.gif

Geoff, where did you defend the honour of the 3D performance?

I'm quite surprised if 3D is only being presented at 540p on a 4K TV and not as 1080p as expected: it beggars belief unless extremely closely spaced polarisers create an unexpected interference pattern. This might explain comments I have read that the 4K TV appears to have horizontal lines: a 2160 resolution TV with alternating polarising strips at pixel widths should not be showing horizontal lines unless viewing very close up, but if the polarisers occupy 2 pixels each...

Check the 55X9 thread and the thread about the Consumer Reports review, I've put my foot in it in both times. biggrin.gif

And I think you're spot on about the polariser...

So I rented This is the End, it's Mi4K and it looks good, sounded even better. I have my PS3 super white set to on and I manually set my Sony TV to x.v. color. Visually, This is the End doesn't have the best cinematography but the color looked rich and vibrant.

Any opinions on what is the best Mi4K BluRay so far?
post #696 of 824
Some of the reviews have screenshots, which helps.
post #697 of 824
I might get Ghostbusters Mi4K, thats really the only movie I'm interested in owning.
post #698 of 824
You are all nuts. This digital stuff is crap. Laserdisc forever!
post #699 of 824
Ghostbusters looks absolutely magnificent. It's not a demo title for clean, crisp images or colour that makes your eyeballs bleed, but it's as authentic a presention of an early '80s anamorphic show as any I've yet seen.

Now we just need Ghostbusters 2, and badly frown.gif

Oh, and Bad Boys 2 biggrin.gif
post #701 of 824
Ok, so we landed on.....This is the End actually is in the 4K family...?
post #702 of 824
Yes, This is the End is part of the Mi4K BluRay. It's a funny, raunchy movie and the PQ looks great but I wouldn't call it reference quality.

Mastered in 4k blu-ray,s have recently been released in Australia.Picked up 10 movies.
I have 2 HT systems with 3 blu-ray players.

The improvements with these disc,s is the higher bit rate and the first use of xvYcc ,extended - gamut colour space .(x.v.Color . Sony designation )
http://www.sony.net/SonyInfo/technol.../xvycc_01.html
With the use of xvYcc mastering and playback ,even products that support xvYcc may not work and some bluray players do not support it.Oppo 103/105 do not.

The good news,Toshiba bdx3200ky enable HDMI deep colour 30bit,36bit , with Panasonic TH-P60UT50 plasma auto detects x.v colour.

Not so good,my panasonic Dmp-bd85 officially supports x.v colour.My samsung plasma series 5 2010 model according to samsung all tv,s after 2007 support x.v colour.With Samsung tv ,auto for colour x.v decoding will not work ,it must be manually selected.
It seems my model does not support x.v colour as the option should appear in menu when receiving x.v colour ,it isn't grayed out it doesn,t appear at all.

Picked up my Sony W900A TV the other day and decided to grab the Mastered in 4K Spiderman 2 Blu-Ray to see what it could do. Having watched the film I wasn't as bowled over as I thought I would be. It looks great overall but was expecting the best-of-the-best if the hype was anything to go by. Then again, I'm not sure how much better it is over the normal blu-ray (I own the movie on DVD) so maybe it's as good it can get. The audio on the other hand is stunning, one of the best mixes I've ever heard.
post #705 of 824
Well the PS4 currently doesn't support Deep Color or x.v. Color! This is Somy's big push so I'm hoping they will add it through firmware.
I will say the games look gorgeous on the Sony W900a though.
post #706 of 824
From what I understand the x.v.color used in the Min4K blurays only works on the PS4 when used with a Sony 4K display (UHDTV, VW500/600ES, VW1100ES or updated VW1000ES) using an HDMI 2.0 connection. It will not work otherwise. Is this the way you are testing?
post #707 of 824
^ it would be interesting to see Spiderman 2 on the right equipment, because from the screen caps it looks like they really messed up the color!
post #708 of 824
**** the caps, Spidey 2 has never and will never be a 'pretty' movie. The old one had far too much magenta and was very contrasty. The new one has lower gamma and a punchier colour scheme, along with crisper detail. I never liked the old transfer, and although the Mi4K isn't perfect I much prefer it to the original.

The "mastered in 4k" release of Robocop now has a street date of Jan 14th. 2014.
post #710 of 824
How many of you have actually measured your tv's color space to see if it is actual in the xv color gamut? A tv simply saying its in that mode means little or nothing and considering how few of them are even capable of doing rec709 well I can only imagine if even one of you are seeing what you think you are.

And how would you do that? As you know, there is no calibration to x.v.color which isn't a fixed color gamut, it' only allow some metadata to display extra color outside of rec709, in relation to rec709. You still calibrate to rec709. There are no such things as x.v.color test patterns afaik, and you would need a bluray mastered with the x.v.color flag or a VP with x.v.color patterns able to switch the display in x.v.color mode to be able to do any measurements. So apart from checking that the display can display more than rec-709 in its widest colorspace (which most do), how do you achieve what you suggest?
post #712 of 824
x.v. color is a defined color gamut so it would be possible to measure a display's adherence to it. As long as you could force the mode on the TV, you would use calibration software like Calman and tell it what space you were trying to measure (in this case x.v) and see if it hits the targets. For proper playback you would essentially want the TV to be calibrated to REC709 for one memory and XV for the other. Any pattern generator should be able to provide the necessary patterns since it is a simple generator. It would only need the coordinates.

I asked Joel from Spectracal, and he was very clear about this. There is no specific gamut for x.v.color. The expanded gamut info is displayed in relation to rec-709, so for example red 110% etc. You can't calibrate to x.v.color because there are no coordinates for primaries and secondaries, which is also why you don't have x.v.color patterns. That or Joel is wrong smile.gif
post #714 of 824
Here is the thread I started a few weeks ago on the subject http://www.spectracal.com/forum/viewtopic.php?f=92&t=4971

For those who are not Spectracal registered users, here is Joel's answer to my question about how to calibrate to xvYCC and whether creating a custom gamut with x.v.color coordinates was an option:

Re: xvycc calibration?

Postby Joel Barsotti » Fri Oct 11, 2013 10:59 pm

The way xvYCC works is by using the extra range in YCC so when converted to RGB it creates negative values. It uses those negative values to increase saturation so 100%,0%,0% is rec.709 red, 100%, -10%, -10% is a value that could be encoded in xvYCC and therefore push the gamut out further.

So all you can do with xvYCC is turn it on and calibrate to rec.709. The extended gamut is based on having the primaries already in the standard location and then differencing off of them. The gamut xvYCC is capable of creating is an odd shape as you can't maintain the same chromaticity at all luminance levels.

I'd wait on 4k tech PERIOD. Heard that the current U HDTV's operate in 60Hz but the inputs at ONLY 30Hz. You need the TV's to be running at at least 60Hz for 4k movie playback.

Also, these "optimized for 4k HDTV's..." movies...They are mastered using 4k then down-sampled to 1080p...then upsampled again back up to 4k when played on 4k U HDTV's. I'd wait for the new format blurays "U HD blurays" (mastered using 4k masters and presented in 4k).

Not sure how useful Sony's current "media 4k puck" and 4k online service (http://bgr.com/2013/09/04/sony-4k-video-store/) is if their current U HDTV's inputs only at 30Hz..

Wonder how long this will take the studios and HDTV manufacturing companies. 1-2 years?

BDD888, I think you need to slow your roll.

All Blu-ray discs are downsampled to 1080p from higher quality sources (scans and DIs ranging from 2K-8K or higher). There are rare exceptions where SD video is upconverted to 1080p, but the Blu-ray discs optimized for 4K is simply marketing speak. That being said, the 4K series of Blu-ray discs offered by Sony are some of the best 1080p encodes around.

Most content available in 4K (there isn't much) is only 24Hz or 30Hz, so you're not missing out on anything. The 30Hz limitation of current 4K TVs is a limitation of the HDMI connection - in particular the HDMI controllers inside the TV and inside the source equipment. You need HDMI 2.0 or DisplayPort in order to exceed the 30Hz limit unless you get creative. Some 4K TVs use dual HDMI 1.4a ports to accept two simultaneous 1920x2160 60Hz signals in order to display 3840x2160 @ 60Hz.

Until we get movies and TV filmed higher than 30fps, it's not going to matter much. So far there's only The Hobbit, its sequels, and probably any future movies released by James Cameron. If you really want to aim high, hold out for 8K @ 120Hz. wink.gif
post #717 of 824
I'm in no hurry Nathan Andrews. Just came across the "Mastered in 4k" and wondered. Yes I realized lots of movies are down-sampled to 1080p from higher res masters.

I've got a Pioneer Elite 141 plasma right now. Haven't had it professionally (ISF) calibrated yet. Terrific video quality. Happy with what's on bluray a/v quality wise.

But what about Sony's "media puck/online service"? Using that deceive with a Sony 4k TV...would we be getting true 4k programming? Without any sampling done.? Just curious. Not planning on investing in 4k HDTVs yet. Too early.

Yes, you can go to Best Buy and watch it now.

My buddy just got the Sony XBR55X900 but needs to get a BD player. Are these still the BD players to get for proper playback of Mi4K titles?

Do they come with the right HDMI cable?
post #720 of 824
Yes, they are still the current ones (or if you buy at Costco, it's called BX-510). No special cable other than HDMI High Speed is necessary
