[Anonymous]

With the release of Calman Business, will there be new workflows with THX reports for V5 with checks for colour saturations be available anytime soon?

Michael and myself will come up with some thing for V5 once it is released.
Just like we did for V4 : )

Thanks Ray, looking forward to it.

Looks Like the calman 5 workflows are using Delta-E2000 instead of 1994. Is dE1994 still the best practice according to THX or is dE2000 the better option now? –thanks

They may default to it, but you can still change them to 76 or 94 or whatever you want.

In some of these cases … just use your eyes to see if you can see a difference between what 94 gives you and what 2000 does. Beyond human perception is still beyond human perception. They didn’t redefine that. Or I missed that memo where all the humans got that upgrade except me. 🙂

There is a move on the academic side to try to get SMPTE to modify the HDTV specs as they currently exist to account for all the different display technologies that exist today versus the CRT that existed in the mid 1980’s when they settled on the HDTV spec. Until things actually get adopted … nothing is going to change. It may be like that best gamma number thing all over again.

The V5 flow that I am working on is still using the base 76 for grayscale and 94 for color. The end user always has the option to adjust those. The V5 program has some bugs so don’t be in too much of a hurry to leap over there.

Further to this … if on most TVs today, you are getting a dE of around 1.5 across the board … then it doesn’t matter which dE formula you used. The 94 is supposed to be 28% better than 76 (?) … and 2000 is 11% better than 94. But when you look at dE numbers in the 1.5 range, even a variance of 28% one way or another is still well below the 3 threshold. It still won’t matter and you still won’t see it regardless of which method you use.

The place where it might matter is when you have tvs that don’t behave nicely … particularly the older stuff or crappy stuff. Then the “better” dE stuff might matter. But then it might not because I can point to almost every instance where the TV controls are either incomplete or broken where the dE says it is correct and the best thing to do, but the image is just plain bad looking. When controls don’t work right, you use your best judgement and don’t let the dE method sway you.

I have paid & has updated to the Calman5 Business Ultimate. I would Like to use an THX workflow report that is like the ISF template with the full calibration workflow steps. is there one in the works? were can I fine the link…

The SI workflows that come with calman give you what you ask.

The THX workflows assume you know what you are doing and only need it for grayscale and CMS stuff. No hand holding.

If you still want access to them, email me. I keep them in my dropbox.
