JVC Autocal Software V12 calibration for 2019 RS1000/RS2000/RS3000/NX5/NX7/NX9

[Manni]

Hi Dave, thanks for the kind words, looking forward to seeing you here

@Manni - when you get your unit and you start playing with the custom profiles, can you have a look at how linear they are?  You basically take a small profile (say 5^3), and create a custom colourspace in Lightspace with the measured RGBW extents as the gamut definition, and then generate a Peak Chroma LUT from that profile into the custom colourspace.  With a perfectly linear profile you'd end up supposedly looking at a perfect cube.

I've tried this on my X7900 with REC709F, REC709NF and then the built in reference profile with a 3DLUT loaded.  Only the reference profile with 3DLUT seems to profile back to a rough cube; the two custom profiles loaded both have what seem to be significant non-linearities.  I'd be interested to know if you see similar behaviour, and if you do what you think of it.  Cheers!

Okay, let the fun begin

I've spend much of the last 48 hours setting up, calibrating and running measurements on my new RS2000, which is sitting on a shelf below my RS500. I'll swap them once I've found the time to measure ANSI contrast in its current (temporary) position.

I've posted some preliminary recommended settings and observations here and detailed brightness and contrast measurements will follow shortly, as well as out of the box calibration measurements.

I'll post some first impressions here or in the owners' thread when I've had more time to watch content. I wanted to calibrate the beast (even minimally) and find the best settings before doing so properly.

Enjoy!

Greetings,


Thanks as always Manni!

I've just posted detailed brightness measurements, with contrast measurements to come soon.

Nice one Manni, shapping up well!   Sounds like you've got a good one so far. 


Did you see Datacolor have launched a new meter - SpyderX?

There are marketing claims around for improvements in accuracy and better low light capabilities.
I know JVC typically haven't supported new meters in released product.  However I do wonder if getting support (seeing as it is provided by an external DLL) might be as simple as switching the DLL for the one for the new meter.


Anyway, might be work a look!

No I didn't see this about the Spyder X. This might explain why the Spyder 5 Pro is on sale on Amazon UK, at the lowest price ever of £99 (a true bargain).

It might be worth investigating indeed, but not before we can check that the Autocal V11 itself works as intended, I'm reading a few worrying reports from trusted calibrators (such as Chad B) that it might not be entirely ready for prime time. We shall see!

I've just posted detailed contrast measurements to wrap the day. I'll try to post some calibration measurements as soon as I can, hopefully tomorrow.

Just posted detailed measurements for my SDR rec-709 quick calibration (no Autocal).

[Manni]

Also added to yesterday's results some contrast measurements taken with the Discus trained to the i1pro2 in Calman to compare with the T10. Max Bright, low and high lamp, iris fully open, manual and auto2. This is mainly to give an idea of the accuracy of the Discus ofr contrast measurements, as this is what I'll be using most of the time.

[Manni]

...and some measurements for my wide gamut (DCI-P3) basic calibration (just 100% white set to D65).


I'll try to post HDR and BT2020 measurements later.

[Dylan Seeger]

I may have missed it somewhere, but how much light loss are you seeing with the P3 filter in the light path?

[Manni]

I may have missed it somewhere, but how much light loss are you seeing with the P3 filter in the light path?

I mention this in the recommended settings and in my DCI-P3 measurements. The filter cuts 20% of light, so you gain 25% by not using it. People rarely specify clearly which number they are talking about, so there is a lot of confusion.

[In low lamp]
Filter (120nits here) = no filter (150nits here) -20%
No filter = filter +25%

I’ll also post the difference in the HDR and BT2020 measurements later.


EDIT: see below, it looks like these numbers only apply in low lamp, which is what I primarily use. I've measured BT2020 and HDR in high lamp and the numbers are:

In High Lamp:
Filter (165nits here)= no filter (185nits here) -10%
No filter = filter +15%

That explains a lot!

[Manni]

I was hoping I could live with my quick and dirty P3 calibration, but the errors especially on greyscale were too visible on actual content, so I decided to run a Lightning LUT (10minutes) with Calman. Much better

All details and new measurements (before after greyscale, gamut, colorchecker SG and contrast) added in the DCI-P3 measurements.

I haven't checked for visual issues yet.

[Manni]

Breaking news:

I think I found why the filter/no filter numbers are all over the place. In my brightness measurements, I measured low lamp because that's what I use. In low lamp, the cut is 20% (150nits without filter to 120nits with it). The gain is 25%.

But in high lamp, the cut is only 10% (185nits without the filter to 165nits with it). The gain is 15%.

Dylan, can you confirm you're seeing something similar?

I've posted detailed measurements in the contrast section for BT2020 and HDR showing the effect of the filter in low lamp and high lamp, but manual and auto (along with the High Bright measurements previously posted).

I've also posted some gamut (P3 within BT2020) and contrast measurements in the BT2020 measurements and HDR measurements sections. I tried to update my recommended settings and a few posts accordingly, but there might be a few mismatches here and there because I'm having some issues with the editor of the site. I'll resume posting when this is resolved.

I've also updated the main index post with live links.

Yes, remember when I posed the question earlier in the owners thread as to how I was only measuring a 10% loss? It seems you found out why. I was measuring in high lamp mode. I'm glad my measurements now match yours.
