Sorry for the noob-questions...
The digital files aren't an ISO, so you can't burn a disc from them. They have to be run from a USB thumb drive. And a DVD is nowhere big enough.

The disc says that the MacCLL and Mastering display luminance is 1000 cd/m2 and min luminance is .0005.

Also MaxFALL 400 cd/m2.

Can you please explain what the above items mean? If the max is 1000 cd/m2 or nits then how do you get patterns above this 1000 cd/m2 max nit amt ie hitting up to 10,000 nits?

The 1000 nits is the maximum luminance for the display used to master the content, and the min luminance is how dark its black is. This doesn't mean you can't have a pattern with the code value for 10K nits on the disc. Your set just won't be able to reproduce it. In fact, no current display can reach that luminance level. But that is part of the HDR ST 2084 spec, and some day you may have a display that can do it. So it doesn't hurt to have a pattern for it. This can also be used in measuring the levels which a display can resolve in its tone mapping (i.e., whether details at higher brightness levels are simply clipped/not shown or the display attempts to make them visible within the limits of what it can do).
IIRC, MaxFALL is "Maximum Frame Average Light Level", and is the maximum average light level achieved by any frame of the video, including the highlights. MaxCLL is "Maximum Content Light Level", and is the luminance of the brightest pixel found in the content.

AFAIK it's the brightest sub-pixel (R, G or B), not pixel (RGB triplet).

The article I found explains it thusly: "Maximum Content Light Level (MaxCLL) is additional static HDR metadata that corresponds to the brightest pixel in the entire stream. The MaxCLL metadata is represented in nits."

Thanks. I've always heard @ConnecTEDDD mention sub-pixel, for example here: https://www.avsforum.com/forum/139-di...l#post52828705 so I thought he was correct (as he usually is).

I wouldn't trust any article, but checking the ST2084 white paper from the SMPTE here https://www.smpte.org/sites/default/...-Ecosystem.pdf seems to confirm that MaxCLL defines the brightest pixel not sub-pixel (see E.2.2.4 P42):

"E.2.2.4 Maximum Content Light Level
The Maximum Content Light Level (MaxCLL) is an additional Static Metadata item that applies to HDR Content
only. Maximum Content Light Level corresponds to the brightest pixel in the entire stream."

Maybe Ted can give us his reference? It would be good to know for sure, as it looks like I was mistaken.

I may have missed it but for the lg 2017 oled can you use the chroma pure or hfcr hdr slides now that lg has defined the adjustment as 1-21 etc instead of the 2016 naming convention.

Not an iso. After you download and extract the files, you will find a folder for TS images and a folder for MP4 images. you can burn both to a blu ray disc or choose one or the other to burn to a blank dvd. They will be data disks so no menu. You will have to navigate through the file structure to get to the test patterns you are looking for. I find using a usb drive easier, but have also burned the files to a blank dvd and they worked fine as described.

Hi Jay,

LG is still utilizing their own grayscale methodology and naming convention for HDR within their 2017 OLED model lineup. However, it has been updated from their 2016 implementation. You can reference the new code based patterns HERE. My last digital file update has these patterns available within the LG OLED Patterns file folder. Thanks!

Ok is this update on the disc as well? I may not have noticed it since I haven’t had to look for a 2017 slide till now

Unfortunately, the 2017 patterns did not make it onto the disc, only the 2016 were implemented. The disc was already past the phase of add-ons and/or additions. Thanks!

Hi Manni, look @ page 44 of the PDF, it says how MaxCLL is calculated.

setmaxRGB= max(R,G,B) , so the max is one of the R or G or B value.

For MaxCLL interpretation, the unit is equivalent to cd/m2 when the brightest pixel in the entire video stream has the chromaticity of the white point of the encoding system used to represent the video stream. Since the value of MaxCLL is computed with a max() mathematical
operator, it is possible that the true CIE Y Luminance value is less than the MaxCLL value. This situation may occur when there are very bright blue saturated pixels in the stream, which may dominate the max(R,G,B) calculation, but since the blue channel is an approximately 10%
contributor to the true CIE Y Luminance, the true CIE Y Luminance value of the example blue pixel would be only approximately 10% of the MaxCLL value.

So if the brightness sub-pixel is blue, its not really be as bright in nits as the MaxCLL number is showing.

@mascior - I see that you recently had a Xbox One S to do some testing of the disc with. Did you by chance look at the resolution patterns I mentioned a while back? Basically they are all "static-y" when playing through the One S on my LG E6. Let me know. Thanks!

Hi Jestered,

The same anomaly that you experienced within your setup, was present during my testing as well. It sounds as though there maybe an issue with the XBOX One S decoder, as I have not experienced this on any other UltraHD player. Thanks!

Ryan,

Is there any particular reason why the 2017 codes do not numerically line up with the 21 point codes in the LG WB menus? I didn't see how any of the 540/1000/4000 slides match numerically. Is there a setting on the LG that specifies what nit level perhaps?

IIRC, the code values LG listed in their document are themselves incorrect.

Ok I just went with what I New would be 100/5 for a two point. As far as greyscale for 20 pt goes they were all under 1.0 after very minor adjustments in the 2pt.

Hi jayraysaiz,

It looks as though LG is still utilizing full range HDR code values (0-669/1023) vs the limited range code values (64-657/940) that should have been implemented. I only offer the limited range values within my current revision. However, I will most likely add the full range code values to align with current software. Thanks!

Possibly within the next two weeks. I am currently working on other updates for REV_017 as well, including more test footage at different nit levels and a few other miscellaneous test patterns. I am also working on DV patterns in parallel...

Ryan do you know if any other software will support Dolby Vision calibration other than calman in the near future?

**NOTE: This revision was compresses with 7-Zip. To extract, please utilize the 7-Zip extracting utility found at http://www.7-zip.org/ (PC) or the Keka extracting utility found at http://www.kekaosx.com/ (MAC)

Revision 17 brings numerous new test patterns, updates, and modifications to the suite:

  • Two new test footage patterns graded at 1,000 nit, displaying different color shades and skin tones.

Hello,

I recently purchased your HDR10 Ultra HD Blu-Ray disc with the UHD test patterns. I am very happy with the product and also with how quickly the product shipped! Thank you very much for putting this together!

I was wondering if you could please help me identify which of the boxes, or between which boxes, would best represent 320 nit on the first white balance test pattern that lists boxes 502-756.

Thank you for your time!

Is there any type of upgrade process for the disk that we can get for improvements when released? Understand that these don’t make it to disk right away. Thanks. SJ

Hi DrRonPaul,

Thank you for the kind words. 320 nit would equal to 62.8728%, utilizing round nearest, patch/box "63% code value 616" would be the best representation. Thanks!

Hi SJHT,

Disc revisions would be very costly, especially when it comes to UltraHD Blu-ray production. However, I may provide incremental releases via ISO patch. This ISO would not provide the entire contents of the original authored disc, but revisions and updates. Existing customers would be entitled to this free patch upon request as a download. Thanks!
