All true but right now it is the only 4K projection device so people suffer with it, and devices like the baselight have a projector probe to do a "closed loop" calibration to improve the PJ's poor performance. A 2K christie, etc. is a better idea for pro work imo....

They finally state in the pdf brochure that the 10,000 contrast ratio is actually described as "high dynamic contrast" which is actually quite low.
I tried to post M.Myer's infamous 2 pixel misconverged picture for the comparable Sony 4K LCoS, but he removed it.
Achieving perfect (or close-to-perfect) convergence (over the entire screen) for a three-panel 4K projector must be one difficult challenge.

There have been many people asking for a 4K Thompson Viper (currently a 3 chip 1080P beam splitter camera Miami-Vice and others shot on it) but it is practically impossible to align the three CCD's on the beam splitter I would imagine that a projector is going to have the same issue. There are now several "4K" bayer mask (single 35mm size sensor) D-Cine cameras which can resolve 2-3K of actual resolution but color is sampled as 4:2:2 and interpolated in post with advanced but slow de-mosaic algorithms.

It seems to me that with digital projection and digital origination you can either have high resolution with loss of color fidelity or high color fidelity with a loss in resolution. I cannot imagine a 12K to 16K (Imax equivalent resolution) with a 3 device projector, so then what a 8K DLP with a color wheel?

There are some very interesting techniques for scanning film at high res and color space. A great example it the Arriscan which uses a 3K monochrome cmos sensor that can be moved with linear motors to achieve up to 6K scanned resolution. This scanner has a set of R,G,B hi intensity LED's which flash low and then hi intensity for each color to make up a hi res, high dynamic range and high color fidelity scan. Amazingly enough it runs at up to 2fps.

Call me a cynic (or realist) but I think there are some very serious obstacles to be overcome in order to get digital projection to match the hi fidelity of a 70mm projection, or even a 35mm one.

I agree. One of the primary lessons I've learned is to never buy bleeding edge technology. Wait for others to make the mistake.
Here the 4K projectors are NOT ready for primetime: else they would be in commercial movie theaters. The commercial 2K DLP projectors are disappointing too as they do not even come close to the resolution of film.
The subject system here is not practical. Only a Saudi price could afford its blurry picture with no video sources. Why not just go to the movie theater?

If I want true super high rez one can buy a 2560*1600 LCD flat panel with perfect registration. I'm eyeing one for digital camera pictures and general PC use:

Picture quality in commercial movie theaters is hit or miss, and the sound quality is rarely if ever better than passable.

Creating a cost-no-object theater on a personal or professional level allows one to appreciate all different types of media presented at the very highest, most transparent level.

A couple quick jibes:

"The 21st Century Screening Experience!" and "There are over 500 [vacuum tubes] used in Ciné Beta!" don't go together in my book. I am very sorry but vacuum tubes are very much a 20th century device (actually 19th century!)

And I have an even harder time with the following: "The business saying “good is good enough” dehumanizes the real-time life experience of art and all it’s creationary aspects. And then you are no longer involved with quality, fidelity, or integrity. This almost always comes down to a commercial decision rather than an artistic choice." Oh, brother - and this isn't true of Hollywood movies? They are very much a business decision and each one has a budget. The producer does decide when "good is good enough" and thus "compromised" So I'm not sure what content is shown the 6 million dollar theater but it isn't artistic by KSS's own standards. Oh, and I doubt Hollywood used vacuum tube amps at every or any stage of the filming making process. Wait, I take that back the first "talkies" in the 30's I'm sure used vacuum tubes in the recording process. Gee, If we could only have that olde timey sound quality today.

There are many other flaws in the preachings of the KSS website. I don't have the time or references on-hand to debunk other claims on that site.

-Mr. Wigggles

Ps. It just dawned on me that K.S.S. is very close to K.I.S.S. or "Keep It Simple Stupid"

The Mothership is now boarding.

For the haters, you might look into the writeup we did over at HTF (no links allowed) on the KSS. Mr. Kipnis is not shy about addressing the doubts we mere mortals have when confronted the idea of spending aproximately 60x the value of our existing mortgages for the creation of a Home Theater. As someone who has met Jeremy and spent some time in his theater I can assure you this guy is the real deal and that this is a business venture as much as a personal entertainment pod in his home. From an engineering perspective it seems solid, tho I agree the location and the website are not optimal =) As he himself explains tho, this is a journey and not a destination, and the current incarnation which happens to be housed in his home is simply one step on a long walk, and future installations can and should be put in more obvious locales.

Hi -

I have just completed a Sony SRX-R220 4k projector review, featured on HomeTheaterReview.com:


http://www.hometheaterreview.com/fro...x-r220_4k.html


My experience with this projector has been hit and miss (out in the field), but under controlled conditions, it at least lives up to much of what 70 mm film can dispatch - and there is no frame stuttering, dirt, scratches, or reel changes!

Comments?

Or may I offer a full demonstration to anyone interested?

Cheers -

Jeremy

I'm definitely coming back to see if the upconverting of consumer media to 4k makes a difference. =)

We covered that in the interview I referenced above. Again the engineering principles underlying the electric feeds are impressive, you should check it out, I dont think any of the magazine articles covered that. =)

as much as i love the typical well integrated mini theater design (mini THX cinema at home, stadium, rack full, curved scope, pro cinema speakers),
this is nice to show off beautiful products

There's a pretty ridiculous "note about reference screens" at the bottom of that page. The type of "info" only a salesman could write with a clear conscience.

Your review missed that the projector does not take a digital input, I seem to remember As expected even small temperature variations degrade performance: no doubt convergence does too Don't even ask the bulb price.
Perhaps if our friendly middle east prince could rent pure digital DCI releases at 4096 resolution, then K.S.S concept might be worthwhile.
However over here, as T. Bone Pickens states, we Americans are paying $700 billion a year to finance an opulent lifestyle. This and the "drunks" on Wall Street, who mortgaged away our future, remind me of the recession reality thread of a few months ago.
Lastly buying dozens of amplifiers over several decades, I know that heavy massive power amplifiers do not sound as good as the lightweight energy efficient resonant switching power supply based amplifiers. Think energy self-sufficiently.

But many in the industry review components which there own countrymen do not take seriously. Take for instance the British and their pushing of $2000 CD players. Somebody somewhere must be buying this obsolete gear now?

I wonder if you really read the review?

I said that it takes just about any digital input (and analog as well) from 480i to 2160P @ 24, 30, 48, & 60 fps, thanks to the four different input card types - including DVI with HDCP.

The white field uniformity is variable over the life of a bulb, but is easily correctable using a special alignment camera and software.

Convergence is spot on! I wouldn't accept it any other way - especially as I enjoy sitting 0.75 screen widths away.

The bulbs are very expensive ($4,950.95 MSRP) but so is the projector. It is what you would expect from the Lamborghini of light engines. So replacement tires (5,000 ANSI Lumens each) are understandably BIG BUCKS!

What's really amazing is that it takes Coca Cola to deliver the quality that the Sony projectors are capable of. I have seen more than four dozen examples (of SRX technology) that are laughable in comparison to film or DLP Cinema.

But the SRX engines do have the capability to look absolutely stellar!

Do they have the same setup in the CocaCola experience in Vegas? I was in that one about 5 years ago and remember it being state of the art for it's time.

Speaking of 4k boxes, saw this on Giz today too:

Coca Cola takes their brand image really, really seriously. I believe they would have been using an IMAX 15/70 projector five years ago. I suspect they are using the same SRX-R220s that I saw in Atlanta, now in Vegas.

Jeremy, did you actually make it to the 'Coca Cola presents' 70MM film festival in Copenhagen this April?
