The above photo was posted on our Facebook page a few days ago. One of the comments to accompany the post was a disbelief that MadMapper could be involved in such a large scale project. What this person did not know was that I had an article scheduled for this week containing text from the persons involved that explained the project in detail. The following was written by based Rafael Pereyra of Visual Lab and Luis Barrera of Anatomico with some slight corrections and editing by me.

MadMapper, Who said protection mapping only?
One of the most common issues with vjing in a large video workspace is the arrangement and optimization of the video signal outputs for LED processors.
If you use a Mac Pro you can maybe have a chance to manage the output video signals because of the multi output feature and Modul8. But you must map each output to fit the desired pixel space in your composition. Large stages require more than an single 4:3 or 16:9 composition, sometimes they require 9:1 or some kind of custom pixel space, mixing more than 2 layers of video along with some cameras, that increases the CPU and GPU usage, compromising your performance.
One great solution we experienced two weeks ago at Viña del Mar Festival. The festival is one of the most important music shows in Latin America, and we used of MadMapper. The show was in charge on MADIS (www.madis.cl), the most experienced stage designing company in Chile, working with Visualists Anatomico and Ju Quezada (www.anatomico.cl).
The festival holds more than 700 m2 of LED panels, 8 LED Processors, 2 Hi End Catalysts systems, a Mac Pro running Modul8 and MadMapper, a incredible render farm of 6 machines rendering a pixel space of 9000 x 1000 in realtime at 60fps, rendering algorithmic visuals programmed by a software called MAMBO made by Proyecto LED from Chile. The experience with MAMBO was awesome, managing a huge pixel space in realtime. Everything was controlled with 2 Lemurs and 1 iPad running the Lemur software.
All this video converged onto a Vista Spider System with 8 by 8 SDI inputs and outputs. One of the big challenges of the show was to convert the huge LED pixel space in one single SDI video signal for all the LED Processors, reducing use of simultaneous outputs for the LED processors. It was a huge remap made by software.

So, what does all this mean? Perhaps these images will provide a better illustration of what was achieved.
And now here is the schematic view of the LED arrangement of the Backdrop.
It is very important to respect the space between LED modules and the gap.
The following graphic illustrates how the gap works in relation to the Modul8 output:
This is what is displayed without the gap:
With gap you can tell the difference, the separation between modules is respected by the software arrangement. So it look natural respecting the spaces and gaps.
We had the change how we used the software for Morrisey´s show and remap a virtual pixelspace in Modul8 using a Syphon output of 9000 by 1000 pixels and remap it to a single SDI output of Full HD with MadMapper. The technical crew was amazed how easy and quick it was for us to do the setup. We used more than 400 quads.
And another screenshot with the MadMapper interface with both the input and preview windows:

This is not the only instance where our software has been part of a much larger workflow. Modul8 has been known to partake in very large festival setups and live broadcast environments. When you have such highly complex setups, it’s nice to have one or two things be simple.
