Unfortunately all of the content had to be recreated, as I'm using a different method for rendering and exporting. My current dilemma is deciding on whether to utilize "Profile 5" or "Profile 7" when transcoding. Profile 5, is typically used for streaming, utilizes full range and ICtCp. Whereas, Profile 7 is typically utilized for UltraHD BD authoring and uses a limited range. I have successfully created a few patterns for testing in both profiles...However, I'm still in the beta testing phase. Sorry for the delay. Thanks!

I would think you need both Profile 5 and 7 or the folks with Sony's and maybe future equipment will not benefit.

Agreed. However, I was thinking from a multipurpose/use case standpoint. Both profile 5 and 7 are the current standard...for now. It's that, having multiple profiles makes this challenging and expensive to create.

Hi @mascior

I just got my first OLED TV and am interested in test patterns to calibrate the picture. In my case, I am going to be limited to just adjusting the picture settings on my LG OLED TV. Is your suite of test patterns good for that, or are yours meant for use with calibration tools?

What are you asking here?
# 1 - Can I use the Patterns to Eye Ball calibrate my set, or
# 2 - Do I need software and a Meter ?

Answer is # 2.

UN65KS9800 - Mine
UN65HU9000 + SEK-3500U / UN75JU7100 / UN55HU7250 with SEK-3500U in UJS9000 Mod Mode / UN40J5200AF / HiSense 40H5507 - Wife's

There isn't any picture settings on the TV you can accurately adjust with just test patters alone(Except Brightness and Contrast, but 99% of the time are accurate out of the box). Additional equipment is required. Eyeball adjustments are not accurate.

What about color, white balance, etc?

It use to be you could use a calibration disc, Avia, or the setup pattern on THX discs to tune your TVs. Is doing it that way not really an option anymore? That's essentially what I am looking to do. Just use some kind of test pattern to tune my picture. I don't necessarily need fine tuned perfection.

No. The technology that people used that for has been dead for many years. With the advancement of accurate bit perfect reference patterns and measurement devices. It has shown that the old disc by eye method was never even close to giving accurate results and you are just as likely to make things worse by eye.

Well thanks for educating me. You learn something everyday as they say.

At the risk of sounding stupid, then what is the use of picture adjustment settings on TV picture modes these days? Are those used in conjunction with calibration tools? I know absolutely nothing on the calibration process so I don't know how it's done, so forgive my ignorance.


So eyeballing wont work. What's the minimum equipment one would need to purchase to even do a basic level calibration?

Thanks for your help.

Most of the settings require equipment. Video processing options like noise reduction, motion interpolation, black frame insertion, etc are all optional. Things like color, tint, white balance, grayscale, color management, etc require equipment for accurate changes.

The cheapest entry level device I recommend is a 2017 or newer Xrite i1 Display Pro. Runs about $250.

Use that in combination with HCFR free software.https://www.avsforum.com/forum/showt...php?p=21638248

Please take this conversation to that thread as we are getting off topic here.

Hi zeonstar,

As mentioned by skschatzman and p5browne, the only true way to currently calibrate HDR is by meter and software (which the cost effective recommendation by skschatzman is most likely your best bet). Unfortunately, due to the way HDR is implemented, it doesn't allow for manual adjustment by eye as with current/legacy SDR implementations. Also, as mentioned prior, it's typically recommended to keep adjustments like contrast and brightness at their defaults, whereas theses adjustment could essentially be performed by eye with SDR. The "Basic Setup" & "Miscellaneous" patterns within my patterns suite are essentially for reference on how your display deciphers specific metadata. Also, for a point of reference for before and after calibrations. I hope this helps. Thanks!

I finally received good news from Sony DADC today regarding disc version 2.0...The first allotment shipped today and I should be able to start fulfilling orders this weekend into Monday. Sorry for the delay. There are essentially only two manufactures that replicate UltraHD Blu-ray and with it being a popular format...there is a constant backup in manufacturing. I would like to thank all of my customers for their continued patience and you should be receiving your orders soon!

Here is a Dolby Vision 10% test patch, 50% white, full range, utilizing profile 5. I would like to see if there are any playback issues across multiple Dolby Vision enabled devices. Also, if there are any users that utilize Dolby Vision via TPG and would like to reference, any feedback would be greatly appreciated. I have conducted multiple tests. However, I would like to compare data. Thanks!

I measured the brightness of both HDR10 and DV 50 % patterns and there is quite a difference. Main reason may be the tone mapping of the B6 but does these suppose to have same brightness because HDR10 is code 502 and DV is 512?


HDR10 105 nits 1000 nit level
HDR10 88 nits 4000 nit level
DV 140 nits

Test file displayed fine on my Sony XBR65X930E TV using it's USB input and built in media player.


I also tried to display the file on:
1) Apple TV 4K using Infuse - did not display/work
2) Amazon Fire TV 4K stick - I tried VLC and Kodi. Neither worked.


At this point in my setup, it will only display when on a USB device plugged into the TV.

Hello All,


I just bought my 1st 4K TV, LG 65C8 two weeks ago. I am using Oppo 205 for my movies, via USB3 or NAS in the back panel.


Can I use the MP4/TS test pattern or should I buy the actual disc to calibrate my TV via Oppo 205's USB3/NAS input?




Thanks

There's a sample you can download to test with

Halo,


I'm sure Oppo will play it fine but will it give the same accuracy from BD disc?


The reason I am asking because someone mention some player will need to be calibrated from blue ray disc to have better accuracy.


Thanks

My Panasonic UB900 does not play this DV file.
I probably need the coming DV Bluray disc from you, to use those.

A question.
The last time I received an update for the HDR10 patterns by email was end of june.
Not sure if there was a new update since than, but when I use this link (which I can still use 5 times), will it download the last version or the version from june?

That's because the ub900 is not DV compatible.

Hi santodx5,

The digital MP4/TS files and disc based version should offer similar results when played through any of the OPPO UHD players. However, UltraHD is regulated whereas USB is not. Also, the disc based version is fully authored with a menu structure that will typically cut your calibration session time in half. Thanks!
