Panasonic Plasma Monitoring Solution for davinci

So what would one need to get up and running in a colour critical environment grading for DCI, Film Out and Broadcast/DVD?
What Plasma?
What Probe?
What software to do the calibration?
Do you need a CMS to manage the color?What about the JVC DLA RS35 projector?
What is the most cost effective most accurate solution out there?

So you have to run Resolve in HDSDI dual link / 3G to get 10bit RGB?
What about single link HDSDI is that only 8bit? RGB or YUV?
Can these panny plasmas take a Dual Link/3G connection?
What about feeding your Decklink HD to a HDLink would that not give you 10bit HDMI out?Rory Hinds

That’s a good question, Pete Putman of https://www.hdtvexpert.com/ whose methods were featured in the blogpost I mentioned above has a really good white paper on setting up a Panasonic Plasma as a reference monitor. I just emailed him (email address found on website) and he promptly sent me the white paper.

good to know! thanks!

Thought I’d chime in as I’ve been looking into this from an end-user perspective (and for a book I’m writing). Using 3D LUTs for outboard monitor calibration of any display requires 1) an outboard LUT calibration device (usually with HD-SDI in from your workstation v-out and HDMI out to the plasma), 2) software for analyzing the monitor (with a probe) and generating a LUT that’s appropriate to your hardware (there are many different formats), and 3) a probe for doing the analysis (good probes aren’t inexpensive).
Keep in mind that outboard 3D LUT calibration only works if the display you’re calibrating is capable of the color gamut that’s required by the standard you’re trying to calibrate to. In the case of Plasma, a 3D LUT will bring the typically oversaturated primaries back into line with, say the standard Rec. 709 RGB primaries that you want to be monitoring with, as well as setting proper gamma for the display.
There are several solutions, some expensive, some more affordable. Here’s a list for your own research:
Hardware (All capable of 3D LUT processing)
Filmlight’s Truelight SDI
Cine-Tal’s Davio
Blackmagic’s HDLink ProSoftware
Filmlight’s Truelight color management system (cms)
Cine-Tal’s Cinespace
Light Illusion’s Lightspace cmsProbes (different software supports different probes)
Filmlight Truelight Probe (for Truelight CMS)
X-Rite Hubble (works with Lightspace and Cinespace)
Klein K-10 (works with Lightspace)
Konica Minolta CS series (works with Cinespace)
Photo Research PR series (works with Cinespace)Cinespace and LIghtspace probe support has slowly expanded over time, these notes are true as of a quick look at the company websites today, you’ll want to recheck. I’m not picking favorites, each of these systems is in use in different post houses. If you’re interested in more information, there’s a lot of good info to be had at https://www.filmlight.ltd.uk, https://www.lightillusion.com, and https://www.cine-tal.com.

My understanding of LUTs is primitive at best…
Isn’t it that LUTs are primarily used for film out work… however now you can work in REC 709 and apply an inverse LUT later..
what other uses does a LUT have in grading? (pre applied looks which will be removed anyway?)
-
Yes as far as I understand if you are going film out then it is absolute essential that you’ll need a 3D LUT, otherwise you’re correct in the case of REC 709. It is advisable though to have either the Davio or HDLink fed to a Panny Plasma to ensure the best calibration and if you are ever going to a film out you’ll be able to feed it the required LUT.

So what does a Davio or HDlink do that a good ISF calibrator can’t do?

It’s just for the final tweaking for color accuracy as on board controls aren’t sufficient. Taken from blog link posted earlier:
Wanted better; got a Cine-tal Davio using a 3D LUT to correct residual color and gamma errors (as seen in the demo room). After calibration, color accuracy was comparable to reference-grade CRT. Best of all: a very cost-effective solution.
Most color critical panny plasmas are driven in this way VTP corp packages the davio in this way with various panasonic plasma models https://www.myvtp.com/cinetal.aspx though the HDLink is significantly cheaper than the Davio.
One thing I think that hasn’t been mentioned, in order to do 10bit with a Panny Plasma you do need either an HD-SDI or dual link HD-SDI terminal board.

Denver Riddle “I don’t think that’s fair to say they aren’t developing the professional series as quickly as the consumer series”
After ISF calibration, a G20 is more accurate and has better black levels than an equivalent 2010 pro plasma, which means the advances in the professional plasmas are falling behind the consumer models. The G20 is a low end plasma compared to the V series too. I think that’s a legitimate statement. In defense of the pro models, they usually have an HD-SDI/SDI input option but from what I’ve read, the input converts the signal to component.
My understanding is that black levels are absolute and if a monitor can’t produce black levels, a 3D LUT isn’t going to overcome that. The model you mention has the exact same gradation steps as a G20, but it lacks 3D color management so if it’s gamut is off, without an external 3D LUT manager, it won’t be able to get as close to a D65 white point as the G20.
Here’s the problem I see with that, but I don’t know for sure, so anyone should feel free to correct me on this…if you’re using a Decklink to calibrate your inaccurate monitor, wouldn’t another LUT interfere with that calibration and end up being inaccurate because the actual monitor’s accuracy is off?
Just a heads up…if you have the cash to spend on a Davio and TH-42PF20U, you’d be wise to skip the pro model and spend $500 more on a 50″ VT25 because Panasonic hired the Pioneer Kuro engineers to work on them. The Kuro is the benchmark HDTV that all other TV’s(plasma or not) are ultimately compared to. I haven’t seen anything official comparing a V series to a pro plasma but CNET actually said the V series is the best TV they’ve ever reviewed besides the Kuro and they’ve reviewed pro plasmas too.
