MadMapper tutorial : use multiple video inputs

Hi, in this tutorial we’ll use Modul8 to input multiple video sources in MadMapper.
You can download the MadMapper demo here: MadMapper website

Here’s what we’re after: 3 different videos mapped all over some cubes:

We’ll need Modul8 2.6.2 or more to do this tutorial.
So launch Modul8.
Load up 3 different footages.
Here my footages are all 320*240 pixels (4 by 3 ratio), for the clarity of this tutorial.

Go to /Preferences/Preview Panel
and set the preview ratio to 12 by 3 (which is 3 times 4 by 3).

Assign your first video to the first layer. Enable “Normalize”, so that you won’t have to mess up with the scaling, Modul8 will adapt it for you !

Make two more layers, and repeat the same procedure. Place all the layers in a row:

Go to the preferences again, under the Misc tab, and set the Syphon output to 960 by 240 (which is 3 times 320 by 240):

For the clarity of this tutorial, I’ve slightly added some color to help distinguish the quads:

Now send Modul8’s output to MadMapper by enabling the Syphon output (Command-Y)
Launch MadMapper.

In the Media tab, double click “Modul8 Main View”, which should be listed under the Syphon section.
Modul8 output will automatically appear in MadMapper’s Input view.

Since my Modul8 composition is very horizontal, I’ve switched the viewing orientation by click the switch icon (Command-Shift-O):

Now load a background picture to test the mapping setup. Go to Menu/View/Change Preview Background and load a suitable picture:

Go to the Surface Tab, and make a Quad primitive. Adjust the portion of input to be displayed on the quad in the Input View, and adjust the Quad positionning and perspective in the Output Preview:

Repeat the operation for the 2 other sides of the cube, each time selecting a different portion of the Input Media:

You now have a different footage on each side of the cube.

The procedure can be repeated for a more complex setup, while tweaking the flipping option of each quad, to give a more complex look:
