I would like to output 4 video streams simultously (and in sync):

1. is it at all feasible running Max/MSP/Jitter?

2. can I just use a single MacPro machine with 4 cards or do I need 4 machines in a network?

if sd you should be at least be possible to run 2 streams with one 

computer (had not the chance to test one of the new intel monsters...)

i am not sure if you can sync videos on the frame level, but start 

sync should be no problem, also via network.

the "direct to window" option what you will want...

which resolution would you try to run?

I will run SD video. So if I understand you well, I should probably be able to run 4 distinct video streams from 2 machines only. if so, could those machines be Mac Book Pro laptops?

hm, you will have a problem with the physical output of a latptop 

which has usually only one external monitor output.

what i did once was creating a video with 1440x520 which is 2 sd 

videos put side by side. i had a dual head video card which split 

this video in the middle to two independent beamers.

you can probably employ a video splitter, which are used for video 

walls etc., to split such a video coming from a single head latop 

output, but in the long run it will be cheaper to get to really 

cheapo pc's with dual head video cards - since jitter runs also on 

thats at least what i did a couple of years ago...maybe there is a 

much better solution right now....please let me know if you find it :-)

i ve done an installation with 3 1024x768 projections from one macbook pro. the trick was to use a matrox multi-display adapter. it appears as a 3072x768 display to the computer and splits it in 3 seperate VGA outs. the jitter patch was rendering simple opengl 3d without any performance trouble (core2duo 2.33GHz MBP).

it sounds like a good money-saving solution. thank you for sharing!
