TripleHead2Go with 3 projectors	Can't Post

Hello,
I am working for a show using Isadora and a Matrox TripleHead2Go box.
I need a different movie on each box output, so my patch has three projectors
displaying on the same 2400x600 stage. For all projectors the 'width' parameter is 33.33,
and the 'left' parameter is 0 for pr1, 33.33 for pr2, 66.66 for pr3.
The resolution of all movies is 800x600.
Please, is this the best solution? Does anyone know a faster method?
Thanks
Dario

That's exactly the way I do it. Works great. I made my movie clips smaller, at 640 x 480 to save some space. No problem getting 30 fps on a MBP 2.33, ext FW800 drive for the clips.

A good follow up question to those with more experience: does the CI projector benefit from the "old" double the size and turn on "direct" method - ie do clips at 400 x 300 scale and playback better when using a 800 x 600 projector than 640 x 480 into 800 x 600 (or more appropriately, 2400 x 600?? There is no "direct" setting on the newer CIProjector actor.

Thank You. There is no 'CI Projector' on my copy of Isadora, but it's Win version. Only for Mac?

Hi

Sorry - I should have said I have the CoreImage version of Isadora - for Mac only I guess, and uses all the OpenGL components inherent in the operating system.
