I came up with this idea to create something for those who are interested in Blending, but would not want to search over the different forums for various Info on how to do it. Hopefully we can create a single thread for the 8022 that could be a good source for what has been found so far to get the best image from a blend setup.
I've spent a many hours and days working on and around Williams blend system. And because my goal was always the absolute best image, I knew what I was seeing at some points along the way, was not good enough. So being an image tweaker. I pushed the ceiling further, and in doing so, we found some very interesting things.
I've sent out a few invitations to the next blend evaluation meet on the 17th of this month. At that time I'll go over somethings we've found to greatly improve on the overall performance of a blend setup. I plan to also show how to tweak the coils and magnetics, which is about 80% of the setup on a Marquee. Geometry, convergence, focus and even matching the two projectors together is not the best part of setting up Marquees. Those coils and magnets require as much attention as well. And that is why I'm not pleased with the setup I've done so far. It looks OK, and could pass as being fully done, but there's something else about it that would prevent it from being where it should be. And that's why I'm swapping out the astig boards, which may be fine for a single Marquee setup, but not for this setup.
Also, If doing a blend with Non-Ultra's. You're going to have to live with not having perfect geometry. Or you'll sacrifice perfect geometry for less "banding" We'll cover this as well.
And another important thing we'll go over is the color calibration. The Marquee is a different machine that in order to maintain it's full video IRE range before clipping, it's very important to start with the right G2 reference before doing the color calibration. And at the evaluation meet, we'll also show what happens when the reference is met. I'd just like to say for now, that we will NOT be using ANY gamma at all on the 17th. And I''ll explain we're not using it.
I will not be covering some things in the blend thread, because I'll not be able to spend a lot of time trying to convey these things on a forum. I would like to share what I've learned so far, and hopefully someone else would show up and do the same. And from there maybe that bit of collected info can be shared with others.
So we have a few items still in route, and they should be there before the 17th. And that is when we'll be looking at digital directly into the 8022. An HTPC will also be there, but as you know. I don't put HTPC's on the same shelf with the true video performers. Though good, I don't like the idea of anything being in the video chain that have or may have preadjusted levels that are not smpte (reference), or would not have the black and white levels at the required reference for the rest of the video chain. So it will be there, but not a part of what I'm doing.
I'm putting most of my eggs in the basket on the 17th, because I can't afford to devote too much time to this beyond that. I have too many other things going on, that must take priority from now on. And with so many experts out there on these things, my absence from the thread won't be missed s much.
It's all about the performance... Got Marquee!
