Resolume Forum

Hi, I try to configure out my setting to know which is the better solution...
I'm drawing a performance with mapping and arena, where i want to use 3 HD 1920X1080 Projector connected trough a TripleHead Matrox to my Imac via the Thunderbolt connection...
Most of the images that i'll use are texture and patterns, and some "normal video images"....

So, to be able to use something like 10 layers at the same times, i'm thinking to create this configuration :
COMPOSITION SETTING : 1280X720
And, in ADVANCED OUTPUT, configure each screen to 1920X1080.... so to use all the resolution of each video-projector...

But I'm a little bit confused, for exemple if i use 3VP, I have to se in the composition setting : (1920x3) X 1080 ??

If anyone know the answer ??? or a tutorial that explain the relationship, between the Composition Setting and the setting of each display in the Advanced output...

Sorry, but is the first time that I'm trying to use 3 VP...

Gonna try to answer to you with a similar example.
I usually work with lower resolitions, like 800x600 basis.
So my composition would be 3x (800x600) = 2400x600.

Now you have some options:
Let´s say I will work with three layers...
Move layer 01 to left and layer 03 to right, so you will end up with layers 01, 02 an 03 lined side by side. Each layer will end up projecting its content to one of the projectors.

Let´s say you want to use more than 3 layers (unlimited) and want to freely mix them in real time, etc
Then you should create all your content sized to 2400x800 (in my example).
Also, you will need to use Advanced Output (on Arena Only), set 3 different slices and use edge blending to match the three different projections in a single projected image.

Hope this can help a little bit.
