multiple projectors with individual outputs-urgent help!

[beanspiral]

Hey there resolume friends,
Urgent question, any help appreciated!!, Gig in two days!!! I am doing a multi media performance where I want to output to 3 different projectors with three different images/sounds from the one computer
the projectors are set up in different parts of the room and I want to be able to trigger different clips on each projector, controlled by MIDI. I thought that the Matrox triple head was the way to go to achieve this, however I have got the event space and what they told me is a Triple head is actually a splitter, is there anyway to achieve the three different outputs, controlled individually? please any help or tips urgently needed
thanks so much in advance!!

I have a system with two PCIe Cards, and use four outputs, one for the interface and the other three for projectors, lcds & plasmas.
You need to setup a composition with the size of the tree outputs side by side, and set each output monitor to the specific render area of the composition.
Next you must set some layers (all that you wants, but take care with the performance) to place in the area of the composition that use each output.

Escuse me about my poor english.

thanks so much for your help, but Im working off a mac book pro and cant seem to do that,
At the moment I have reduced the size of the 3 layers to fit all within frame of the output, which I can then trigger, but the problem is that they are all in the same frame/ out put across the three spaces, so you see the same thing in each area rather than layers triggered individually for each output, which is what I originally wanted to do. The other problem is that I'm in China and can't get a hold of a matrox triple head in the time frame i now have,
thanks again for your help

A Triplehead allows you to output one very wide projection like 1920x480 for instance, spread across three 640x480 projectors. You can then use the layer controls in Resolume to let the clips that trigger in a particular layer only appear in one third of the image. So layer 1 would have 640x480 clips triggering on the far right, layer 2 would have 640x480 clips in the middle, and layer 3 would have clips on the far left. So you should be able to do what you want with a setup like that.

I hope that makes sense.

Thanks so much for your help and info, totally understand what you are saying, and that is what I have done so far, however the three areas of projection are not side by side, rather in three different areas of the room, so what i wanted to do was to have one layer of images triggered in one cornor of the gallery, then on the other side of the gallery, have another layer of clips going, and then at on roof of the gallery have another layer able to be triggered. At the moment my three projectors are all out putting the same three images split into three -sorry i hope im making sense!
thanks again for all your help!

There is no problem:
When you have the three outputs on your system, you set up the composition like this:

when every display set a portion of the composition (in this example, the display3 is the center of the composition)

Then you setup every layer to the desire position, in this case, layer 1 at the left, layer 2 on center adn layer 3 at the right.

Every layer was output on the desire display, doesn't matter where the projectors are.

Hello,

what is the difference between Position X and Anchor X to move the layer into the composition??

[HerrNieDa]

the anchor position marks the middle of the clip...
for positioning you shoult use position
if you want to scale or rotate the footage for example from a corner and not from the center, you need to set the anchor point (and the position).
it's like in every other video-application, also photoshop works with anchor points for example!

Hello,

My problem with the proposed solution is that when I do a scale or a rotation, the layer 1 (to videoprojector 1) will go over the adjacent layer 2 (to videoprojector 2).

Is there a way to isolate the two or three parts of the global composition in order to benefit from all the effects and distorsion ?
The problem comes from the fact we can not use the mask option: the mask is applied before layer compositing and effects. So I can't really isolate the different images sent to the different outputs !

Has anybody a solution ?

Thank you very much for your help !
