Multiple Projection in 4800x1080 Pixel Help

Hi all

I am planing a multiprojection for an encore system.

My output resolution should be 4800x1080 pixel wit a ratio aspect of 44:1.

We use 3 HD Beamers with an encore and watchout system.
I allready have a Mac Pro 3.0 xenon 8 core with 16 GB ram, Nvidia 4500 quatro and a ATI Radeon X1900 XT dual link. I was planing to send out 3 x dvi each in a resolution of 1600x1080 pixel.
My questions are:
1.Is it posible to play one big file from M8 to output on the graphic cards
2.How do I have to set up the panel and advanced output settings
3.as we use prcticly 3 HD Beamers with each a 16:9 HD resolution Content how do I calculate the aspect ratio of 44:1 in the footage I will produce in Combustion.
4. is the photo jepg codec ok for QT 7.2 or do I have to change the codec into Motion Jepg or an other (better codev) like the H264



Thanks

Benno

Working on a "same" project. I suggestst>, test test and test everthing on your own system... Never trust some words online ;)
Only thing I can advice is to make a raid 0 with two extra harddrives in your macpro. Photojpg is imho still better than h264 if you work with hd. Just try different jpg setiings untill the system van handle it (still jpg75 is easygoing on a mac,)


btw some maths. The audience has to be in the range of max 2,5 times the screendiameter, otherwise you will never see it's hd... (1080 is not easy!! i keep it with 720p)

Good luck!

cheers RR

Cool sugestion 720p

Funny, I can go to to NY now for a cooperate clip, but I prefer some freestyle time here in Amsterdam to work on my footage. Will be there for sure soon.
And next summer I will be in Berlin for some weeks....
