"World Premiere 4K 3D DLP passive Stack"

After years of waiting a dream becomes true.

One Barco 4K Cinema DLP the DP4K-B32 was install on 3th june 2011 at my home cinema.

With this 4K I did a lot of tests also one with a new Infitec System calls
3D of excellence
and as it went very well I order a second Barco DP4K-B32.

The old pr. room that have the Barco DP 2000 inside was removed


the old pr. room was gone....



This second was installed last Friday the 1th july 2011.

After this install i put the new Infitec System on(temporarily at the lens) set up a computer that
feed via 4 display ports the two 4K DLPs each with a 4096x2160 image.

the 4K 3D computer with 4 displayports to feed both 4K Barco



4K Pr. number one is down at the cinema and got the install


a fist light with a true 4K test pattern


I hear from Barco Infitic and other company's that must be the first 3D 4K passive set up in the world
with a 4K DLP system.

There are less than 20 installations worldwide at this moment running a DLP 4K Stack but not one of them show native 4K 3D content.
So the 1.July 2011 was a World Premiere


4K Pr. number 2 arrives the cinema


As 4K3D native with one 4K DLP is may a good year away and shutter have also some weak parts I decided
to go with this passive 4K 3D set up as it have a lot of advantages like:

-having 4K 3D TODAY and no need to wait for next year new input boards that makes native 4K 3D possible with only one 4K DLP
-double the brightness compare to a active 3D single pr. set up
-see both pictures at the same time (for blue ray in 3d its very important as 3D motion looks far better)
-no need active shutter that have Front Wave Distortion Bug and other picture quality decreased issues.

AND thanks to the new 3D of excellence Infitec System
-no ghosting AT ALL even at this high FTL numbers!
-no speckling from silver screen
-no hot spot from silver screen
-no emitter problems in some far away areas
-more brightness


a very rare picture my Barco DP 2000 with two new 4K Barco


As I report since long time ago at AVS with a 4K DLP the source will becomes very important as this is in 99% the bottleneck and will limit the
possible quality.
If you scan even a good 35mm print most of the time you will find not more than hd resolution as the 400 or 800 asa films not contain
much more than this.

That's why I spend since many years much time money and action to record my 3D Stills with the best possible digital cameras that are
buy-able and possible to make a mirror rick in 3d.

Now for the first time I know why I did that as the bottleneck is not anymore the display system!


Its hard to describe how good this pictures looks.
One very big advantages from using 4K DLPs are that you can go very very close to the screen without any visible pixels and decrease
of details.

That's why I create a new first row that have in flat format (1,89:1 = 4096x2160 that I most use to display my 3D stills)
0,8 times the distance from the screen wide.
The displayed image is there 5.4meter wide 2.86meter high and I sit there in only 4.4meter distance.

At this distance the picture is still very sharp no way you can do it with only 2k resolution as there the picture suffers form the
4 times less resolution.

The 3d picture is very bright thanks to the Barco DP4K-B32
http://www.barco.com/en/digitalcinem...uct/2310/specs
with a 6000 w. xenon lamp that have around 32.000 lumen and
the new Infitec system that have set a world record light out.
This system is even brighter than Dolby 3D System and allows me depends on what size I use in
flat 5.4 m wide or scope almost 7m wide till over 40 FTL in 4K 3D measured after the glasses what you eye see!
In cinemas you must be lucky to see more than 4 ftl in 3D and new tricks not solve this issue.
Some will say to bright but some early visitors may think first the same but after they see it they say that is bright very nice
No one say it was to bright.

For all that have no access to high quality 4K 2D or 3D material a 4K pr. make not a big sense beside you are future proof.
A good BD in 2D looks upscale to 4K not far better.
You can only see a small improvement in picture quality it looks a bit more naturally that's all.
But if you sit close to the Blue Ray picture in about 1.0 times the screen wide in distance it makes sense as you than with a 4K DLP can not see any pixels.

It will be still a long way and will take much action to rebuild the cinema that it will be look again nice and with all the new much stronger exhaust air system new sound proof projector room, new system to not need any porthole glass but it will be make fun to plan and build it.

the Barco DP 2000 was gone the 2 new Barco 4K with the
temporary Infitec set-up




I have to say thank you Barco (Ignance, Dirk and Philippe) to help me a to create this setup as for sample I can use
new software to feed my 4K 3D Images that will be soon(in some weeks) released to the public and much more.

Also Infitec that give me the new 3D of excellence filters to test it and the offer to equip both Barco DP4K-B32 with this new filter that I can
move in and out to have the flexibility to watch 2D and use at the same time 3D.
This new filters and glasses will become available till end of this year.

Also Mr. Trautner from Austria that build first time this kind of computer i have to say thank you for your support and the time you
spend with me for this project.

FTT in Germany did also a good job to install and adjust both pr.

Mr. Peschke (the In Camera Magazin called him the 3D brain from Germany) I have to say thank you as well as
he creates with me this insane Leica M9 3D 3D Rick that can do 3D pictures that have a quality that I never saw before.

All this was not possible without the 3D processing program Cosima from Mr. Herbig Germany.
This program allows to do anything you like for 3D pictures and 3D video and as he update his program all the time.
It's a perfect tool and a good workflow for me in 3D.

Last I must say I was very surprised with all what can go wrong in this huge project that not anything major
went wrong and all is ok from the beginning on.
That's a big surprise for me.


new first row at 0,8 times the screen wide in distance


But the biggest surprise for me was how good this 4K 3D pictures look.
I expect that they should be good but I never believe that the distance to my old setup (single Barco DP 2000 Cinema DLP) that
was already very good was so great.

4K with the right display the right source puts you into a new world if you sit close enough.
Its like you looking outside a window and you are there inside the picture.

Next big improvement will be a holodeck

thanks for all the nice words!

as i have post a handfull 4k stacks working worldwide right now but they either display 4k in 2d at 24p or 3d2k upscalle to 4k3d and not "native" 4k in 3d.

the event you mentioned they show there 4k in "2d" with 24p and 3d from 2k source material upscale to 4k so not native 4k 3d.

silver screens not have any "extinction *time* of 150 ms" i say that silver screens have
extinction *ratio* in the best case at 150:1 that means the ghosting is bad.
as it was not that good thats the reason why the ghostbuffer the source material
for almost every 3d movie.

the lens is the 1,27-1,86

some more infos.

here a picture how the 3d4k picture was created with the COSIMA programm.
a 4096x4320 resolution(2160x2) picture split in up left and down right part from the
3d picture.



thats my old canon 5d mk2 a big good heavy 3d camera that i use
till last year.




here my last 3d camera a hand build leica M9 3d camera.
Mr. Peschke desing the rick
Leica makes the coupling and sync box and the new cover.

Leica have to redesign the top part of this camera because of the original M9 up cover plate have not enough room for the conctor for the sync but a M8 up cover plate have it.

so this two M9 are the only 2 units that Leica build that have a M8 cover plate!

i bring all together and procure a very high end beamsplitter.

that Leica 3d rick is a very very compact full format digital 3d set up and the best i ever had.
some people say its the best full format sensor still picture digital camera in the world and i must say that i saw till today nothing that beats this M9 camera in picture quality.



i build 3 ricks.
one i use the other one is with leica and the 3th
is for someone that is as insane as i am about 3d.

sad that Leica not produce """this""" camera:
please note that this was a fake picture i create!


but if such a high end 3d camera will be ever produced i will be very happy.

this rick i use have one big advantage over a true 3d camera
with a fix optic distance.
you can there adjust the base
between both optics but this beamsplitter cost you around 55-60% light
produce color problems compare to a real 3d camera.

i hear that some companys will have soon a real good 3d still picture camera.
i guess sony and panasonic will be a candidate may canon as well but i doubt
that they will comes with a full format digital 3d that match my quality
ideas.

but the next dream will be to have a true 4k video 3d recording like for sample
a red epic like they use for shooting 3d films at this moment.
sad this rick will be huge and havy but i hear also that some camera manufacturer will have a video 4k function for film very soon.

a problem will be that at this time the 4k dlp can not display 4k native resolution with more than 30 frames.
the new inputboards that can do it in 48p and possible 60p in 4k native
will take some time.

i may will consider to share some of the pictures in future.

its my hobby family and more not professional photography but some
very top company that everybody knows use internal my 3d pictures for tests and more.(in full hd as well in 4k)
with some of them i talk about a licence to show some to the public at shows for sample.

a.cinemascope looks very nice.
you hear from uwew how he like casino rojal and he saw almost everything.
"if i understand you right" this will not works as every lens are a bit different.

b.no

c. today its not color correct. a big advantage from this new filter is that you not "have" to do it.
it will looks better with the correction no question but i am not sure i will do it as i like how biright the picture looks now and with the correction i will loose some may 15 % or even more.
not forgeth my lamp is a 6kw xenon and the lifetime is only 600 hours.
as this kind of lamps drops fast i may need to change it all 300 hours as i not like it dim
as the price for such a lamp is not to bad ist ok as i not use this pr. more than 300 hour a year.

tomorrow is a big day again.
my 4k imb will be put inside one pr.and the other 4k pr. will be equipped with a hd sdi inputboard.

so than it should be possible to watch Avatar Blue Ray in 3d with this passive
stack as i now can use your doremi dimension 3d you send me.
there is only one problem as pr.1 have the imb inside and pr. 2 have a other
inputboard inside that both pr. have a timing problem.
lets see........

as i have my own 3d cameras NO.

but even if i not have such cameras the answer will be NO as well.....

yes darin using a silver screen and this new infitec system is like you
heat up water and cool it at the same time

i am very busy at the moment.
Infitec was today there to find the right construction for the filters INSIDE the pr.
FTT today try to implement the 4k imb but we are still working on it.

the other pr. will get a normaly HD SDI inputboard but that also
not working at all.

norman
uwe drives 16 hours in one day 1200km to see this set up......
you can "almost" can take a walk.

it will takes min. additional 8 weeks before everything will be nice looking again but bd in 2d and 4K stills in 3d native 4K are running without any sound
now.......
the highlight is anyway 4k in 3d nativ at 0,8times the screen wide and that is
ready if you not complain about noise from the pr.

btw i got used to the lumen in 3d this set up have......and you know what this means

Today was a long day…..but lately we had a big success.

After so long without any result finally the 4k imb starts to work
just before we say "we give up". thanks to the pefect
support from doremi.




I try bd in 3d and YES it displays it in 3d.
Just need a 3d bd player and a hdmi cable plug into the hdmi input from the
4k imb a emitter that drive the shutter and a box that generates the sync and you can see 3d bd that looks better than in every cinema.

Also cinema content 2d and 3d playback from the server.

There was some issue as it seems that both pictures (left and right from 3d bd) are not 100% on sync but I have to look into it tomorrow as there was some adjustments possible but today it gets to late.

the other 4k dlp get a normally hd sdi inputboard but for some reason(we thing the encryption on this inputboard was not there)
it make problems and we cant get any picture from this input board at all.

I hope I not have to invest in a second 4k imb as this units are not that cheap as it was a complete cinema dci server with a imb board at the
pr.input side with all it inputs you need.
for sampel it have G3 inputs that are new hd sdi with double the bandwidth hd sdi have and hdmi as well.
also it have more than 3 tb memory......

Infitec did some tests with the 4k to see how much heat this filters inside will get and more.........
