Sony "Mastered in 4K" Blu-ray Titles May 14 and July 16

Anything above 234 (reference white in a video system) is whiter than white, with only a select few Blu-ray titles with any information above 234 encoded. But calibrating to 237 - 240 is ok, to allow a little more headroom.

Yep, it clips everything above 234 with SW set to OFF, irrespective of the contrast setting on my TV. Set to ON I can see clear to 253. As you say, that's above white anyway, but it's still slightly disconcerting that the PS3 clips WTW so readily. My Panny player goes up to 253 on the same pattern without any fiddling of settings.

They sure are expensive. I can get the 4k 55" X900 through the company my brother works for just under $3000, which isn't bad considering I paid $2000 for my current tv only 2 years ago. Though there is no way I'm investing in 4k at this point in time.

It's not the case for the movies, it's just the promotional box retailers have sitting on a stand next to the UHDtv's, advertising that you get all those 'mastered in 4k' titles for free when you purchase one. I would assume that you get them via redemption from Sony rather than them being in the box with the tv. They could come in a boxset or just individually, I really don't know.

Have there been any more announcements for MI4K Blu-rays? I know new Sony releases are now MI4K

[blu-ray_girl_fan]

The new Fry's ad has the Mi4K version of Moneyball listed for $9.99.

The Panny BDT320 can pass xv colour, however the colour space setting on the TV must be set to xv colour manually because the auto option doesn't pick it up.

The slim PS3 is a little more complicated. The TV still needs to be set manually to decode xv colour, but even when the Super White option is set to OFF the PS3 still seems to pass some elements of the extended colour, as the concentric squares in the S&M test pattern still show up. The squares get more saturated when SW is set to ON, which I suppose is the correct setting, but I also discovered something else: when SW is set to OFF, the white range gets crushed to oblivion, so I'll leaving the SW option ON regardless.

So, basically if I enable xv colour in the TV's menu then it can display the extended range. But can I see a difference if I switch back and forth when watching an Mi4K disc (tried it with Spider-Man 2 and Ghosbusters)? What do you think?

I have read that some clearly see a difference in the color gamut, and others, like yourself do not. A possible explanation may be in red/green color perception.

The Ishihara 38 plate test is still widely used by the military. When I took this test, in booklet form, it was to qualify for electronics in the USN. I was given 3 seconds to answer each question. Passing was 100% and missing 1 was failure. I passed. The test was critical, since at that time all components and multi pair cables were color coded.

Since the color xvycc gamut involves red/green the test might shed some light on the issue for you. Click on the gray square in the link and begin the test. Be honest with yourself. No do overs. You can share the results or not. Up to you. The color accuracy of your monitor could affect the results. The best way to take the test is in booklet form.

I just took the test and I got 1 wrong. I actually thought I was going to get more wrong.

Pretty neat. I guess I'm good to go, as I only had one "partly correct".

Well Done sir.

Heh. Correct on all but one, which itself was partly correct because I mistook a 97 for an 87.

Dude, you've gotta bear in mind that the extended gamut on these discs is exactly that: a mere extension, very often in very small parts of the image, like a red headlight as seen in the AVS spectral samples of a shot in Spider-Man Mi4K.

As I said before, the image isn't suddenly transformed into a technicolour rainbow riot when the xv colour is activated, not least because the (properly calibrated) colour is so good anyway. And I don't have a colourimeter built into my head so I can't objectively say that one Blu-ray has reds outside of 16-235 and the other does not. A side-by-side comparison using two of the exact same TVs and BD players would possibly yield more definitive conclusions, but that ain't gonna happen.

[Tech-UK]

Geoff, could you post a link to the spectral sample of Spidey over on AVS.

Thanks.

Ended up getting Ghostbusters mastered in 4K from the UK. Watched it first time without the xvYCC. Now after reading the thread, tried to enable xvYCC on my system.

So far reading my Panasonic DMP-BDT310 blu-ray supports it however only in AVCHD content. My settings are set to:

Color Mode: YCbCr 4:4:4
Deep Color: Auto

I am using dual HDMI so the video isn't touching my AVR

I double checked my settings I had set for my Samsung 55" LED D7000 and I originally had xvYCC turned off. I turned that setting to On (I am using a custom color space etc from when I calibrated my display) and checked Ghostbusters.

Was hoping to see a message appear on the screen or where it says 1080/24p to say something like "xvYCC color" but nothing appeared. Now I can't tell a difference, not sure if I meant to have another setting turned on or something but didn't notice a brighter display like some other members noticed. I pressed info and nothing comes up saying its on (anyone with a Samsung display confirm if a message comes up?). Now alot of members in a few Samsungs forums just always said to leave "xvYCC" off as it can interfere with the picture but this was a few years ago. Now we are starting to see some movies now with xvYCC, not sure either to leave it on (it claims it does not affect picture on titles without it) or turn it back off (which I have for now) as I only have two titles encoded with it (This Is The End Blu-ray is the other one).

[Tech-UK]

ADstv, If all the settings are correct it will be on, but it will not say its active. (not all manufactures include a message) The difference in PQ should be small if your equipment is handling it correctly. If it makes the image look brighter, washed out or over saturated, then there is something wrong.

xvYCC isn't an absolute colour space, which means its result is based on the type of display you have and how it can handle/display the extended gamut.

What I would suggest is start with your display being calibrated as to the Rec.709 standard, and then enable x.v.Colour and observe the result. As I said, if there is a big difference, turn it off, as it will actually degrade PQ.

I couldn't notice a difference in contrast or anything when I changed that setting. Did a quick test using the basic patterns on the AVS 709 disc and my black reference levels are still the same etc. So I would say there isnt any issues with using xvYCC. Previous advice etc had always advised to leave the setting off but with quite a few Sony titles now using the xvYCC I think I will leave it on now

[Geoff D]

I'll keep switching back and forth for now as I don't quite trust the xv colour enough to leave it on all the time with non-xv material. I suppose the best thing to do is try another colour/greyscale calibration with xv colour on and compare the results with my reference measurements.

No plans on purchasing a 4K TV anytime soon, and i don't know how legit this is but Tiger Direct has a Seiki 39" 4K set on sale today for $499 for anyone who really wants to grab one now.

After spending some time tonight tweaking with playing with the setting on and off, I could not notice any difference with the my normal test material (Casino Royale) and AVS 709 tests with xvYCC on and off. However left the setting on and decided to do a quick test with This Is The End and although the menus etc looked the same as it normally does, I did notice a slight difference in brightness and contrast as soon as the movie started. The colours looked it did have that more pop especially with the reds and whites.

So I would say that xvYCC is working there. Even stopping the movie it took alittle longer than normal to switch back to my home screen (same happened to Ghostbusters).

For now I wont invest in 4K until the next HDMI spec is released.

From what you have said, it seems to be working ok. As long as its not doing anything strange to non xvYCC encoded material.

Do you have the Spears & Munsil 2nd Edition test disc? That does have a xvYCC test square in the clipping pattern.

Any informations about the next wave ?
Which titles becomes next the mastered in 4K threatment ?
