REDray Projector..

[paulherrin]

found this from jarred:

You only need a silver screen for front projected 3D... If you only plan on using our Laser projector for 2D.. a white screen is fine.

And remember.. since we are shooting 24 foot lamberts you don't need it to be high gain. A higher gain screen improves the effects of polarization but also gets into all sorts of other issues like hotspots etc.

You guys that saw it yesterday should come see it again today.. we made some substantial improvements late in the wee hours today :)

isn't that the main issues with polarization?

The silver screen I saw today at Red's demo booth had no hot spot, and didn't even look like a silver screen, for that matter. I was more concerned by the raised blacks and my right eye was greener than the left, but this color shift may have been the glasses quality. I'm guessing that it's using lcos to modulate, with laser as a light source only.
it's all prelim, so no worries.
The presentation was 2k simultaneous to each eye, they said they may have 4k in the next day.
It was very watchable, I must add.

The best 3D I've ever seen was at CES this year, on LG's OLED flat screen. Similar to the Red projector, it uses polarization and shows simultaneous left eye/right eye images. It was spectacular, even though the horizontal resolution is halved to each eye for 3D, which wouldn't be the case with the Red.

So, I'm a big, big fan of simultaneous left/right 3D. Something like the Dolby/Panavision stuff that has been discussed just above has the potential to be just amazing, and I wish that it was the solution out of the gate for this machine, but it's not. I'm not saying that Red made the wrong decision here -- just saying that the solution they have used really won't work for me at this time.

Unfortunately, since I just bought a (fully custom) screen that's worth about the cost of this projector, I will not be replacing it anytime soon. I realize that the polarization is only an issue for 3D, and it's true that 3D is not a major focus for me. I own a total of 4 3D Blu-ray discs, in fact, with plans to buy a fifth. But, it'd sure be nice to be able to watch those in 3D if I feel like it.

Another option, of course, is to simply buy an inexpensive DLP that does great active 3D and unremarkable 2D. I would use this second projector only for 3D, leaving the Red to handle 2D on my regular screen. This solution would cost substantially less than adding/replacing a screen like mine, and it's a solution that a number of home theater owners have used, because the category-leading 2D projectors in the $10k and under category (JVC, Sony) have until this year had stellar 2D and less-than-stellar 3D. (This year, a couple of the sub-$10k projectors are pretty darned good at both...)

However, it seems to me that one of the big kick-ass features of the Red projector is the simultaneous, 120Hz 3D. In the absence of widespread 4K content, I don't think you're gaining a lot from the 4K resolution, so the awesome 3D is one of the big features, and without it, the case for the Red becomes less compelling.

There's still a lot of appeal. I would expect the Red to have extremely rich, saturated color (which typical Blu-ray content can't take full advantage of, but perhaps RedRay will), hopefully instant-on and care-free operation like LED-based projectors have, and which conventional UHP-lamped projectors emphatically lack. It also has the potential to be very quiet.

So, it will still be extremely interesting to see how this machine performs when it ships, but I will not be waiting for it. The first projector going into my new theater will be something else. :(

Dolby and Panavision use spectral filters in their 3D projection, the filters are developed by Infitec and Omega. "The filters transmit narrows bands of red, green, and blue for the left eye, and slightly different bands of red, green, and blue for the right eye. A discerning eye might notice a very slight difference in color between the two images, but the brain doesn't care, easily integrating the two into natural color." That quote came from an article that I will link to if you wish to read more. The great thing about spectral 3D is that it doesn't require a silver screen and eliminates ghosting (or is at least that best solution for dealing with it). The downside is that the glasses are reflecting the image that is not meant to be seen by each eye, and if you have ambient light in your theater you may notice the reflections on the lens, you can see what I mean in the picture below. Lasers may make it hard to use these filters since they usually operate on a single line of spectrum, but the designer of the Omega filters has stated on avsforum that it can be done. Don't get me wrong though, I love what RED is doing and simultaneous L/R 3D is more important to me that the fact they are using polarization. If they have a screen in the works than can eliminate ghosting and still look good in 2D then I will be ecstatic. I even have a pair of oakley 3D glasses left from when I used polarization with a dual projection polarized setup.

cool, thanks for the detailed explanation :)

I've been tooling around with a RealD-ish modulation filter which basically converts an active 3D projector into a passive one. Unlike RealD's modulators, this one is aimed at and priced for consumers, and works with any active 3D projector which has a VESA-3D connector for external sync. I've tested it with a couple of Optoma projectors on a Harkness Spectral 240 3D silver screen, and the results look very good. Sure there's crosstalk, but no more than on my JVC X70 active 3D projector.

While RED's projector is 4K and has those friggin' lasers, I'm also very keen to see what its simultaneous L/R looks like. RealD and this consumer version are both non-simultaneous, after all.

For anybody who has already attended today, have they mentioned if the projector is now running at 4K?

I'm very interested as to wether this will suit an IMAG situation for live shows, what kind of gear I would need to project graphic content direct from a computer, and most importantly, cost of ownership. Lamp life, display engine life, replacement costs etc.

Still running 2K

But this morning i am been told by ted that the projector has not been changed/updated since monday ...

yup.. same thing i said. I said yesterday yesterday..
