This is what I was trying to explain. It is easy to create a map that only allows points to come through from a video file. If you create this map in the shape of the Web LED you want to use you can place that in WYG and map the video capture to it.

I strongly do not suggest using more than 4 universes in a visualizer program. In this example, you wouldn't need to.
