How to Use Proclaim in a Double or Triple Wide Environment

Many churches would like to make use of double or triple wide display outputs to create stunning and immersive environments. To accomplish this, you normally need to use multiple projectors and edge-blending to ensure that there are no gaps between the projected images and no bright spot for where the images overlap. 

Proclaim does not support these wide aspect ratios natively, but can work with other software to accomplish this fairly easily.

 

Here are the components I used to accomplish this:

Hardware:

  • Macbook Pro
  • Matrox DualHead2Go or a TripleHead2Go
  • 2 monitors to simulate two projectors
  • 1 monitor for Proclaim to output to
  • 1+ monitors to control Proclaim, Syphoner, and Millumin

Software:



Overview

We will capture Proclaim’s output with Syphoner and send it to Millumin. Millumin will handle sending the feed to the two Projectors, including handling the edge blending and overlap.

Step 1: Syphoner and Proclaim

 

In order to get Proclaim’s output to the two projectors, we will first need to capture Proclaim’s output with Syphoner. Syphoner will create a Syphon server that we can use inside Millumin.

 

NOTE: Syphon is an open source framework for macOS that allows apps to send and receive video content from each other in a performant manor.

 

We will need to send Proclaim’s output to a monitor whose only purpose is to be captured by Syphon. If you are using a Macbook Pro, you will not want to use your laptop’s Retina display as the pixel count is so large the frame rate will suffer significantly.

 

In this case I used a regular Dell monitor plugged into my laptop’s HDMI port.

After you go On Air in Proclaim, open Syphoner. You will see many windows listed. Look for one from Faithlife Proclaim that seems to match the resolution of the monitor. In my case it was the one that was 1920x1080

After selecting the right one, hit the lock mode switch in the toolbar. Note: this last step is important, if you don’t lock Syphoner, the preview will negatively affect your frame rate.

In the top of Syphoner, it will say “Please open a syphon client”. In the next step, we will open Millumin which is a syphon client.

 

Step 2: Configure Millumin

 

Millumin is a very powerful piece of software that can accomplish a whole lot of video and lighting effects. In this tutorial, I will be focusing on the multiscreen options and the edge-blending.

In Millumin, create a new project. Then expand the tray on the left, expand Inputs, and drag the Proclaim Syphon input down to the first layer.

After adding the syphon source to your layer, open the Output settings in the toolbar.

Here you will change the number of outputs to 2, for our 2 projectors. Change the aspect ratio to the aspect ratio of each projector. And select each projector in the monitors presented below. Additionally, here you can adjust how much overlap there is to perform the edge blending (soft edge). Hit OK in the bottom right to return to the main screen.

The last thing is to make the syphon output from Proclaim fills the whole screen. To do that, make sure you have the move-tool selected and click on the layer. After clicking you should see some movement handles appear. Adjust the handles such that Proclaim fills the entire window space. You may have to zoom the canvas out to see the whole thing (using the scroll wheel on your mouse). You can also expand the Layer settings on the right to get access to more fine-grained controls.

The last thing to do is hit the lock on your layer to prevent accidental movements, and now you are done! If you are not seeing your output from Millumin, hit CMD+F on your keyboard.

Conclusion

 

That is it! You can do many more cool things as well with Millumin. For example, you can apply effects to layers such as a blur effect.

In this gif, I have two layers: the bottom layer is Proclaim’s output set to fill the screen with a blur applied. The top layer is Proclaim’s 16x9 output fit to the screen with its edges feathered. This fills the entire screen space without having to crop Proclaim’s output. Which is great for content not made for double or triple wide.

MIDI and more

 

Not covered in this tutorial is Millumin’s MIDI support. You can set up different columns in Millumin to fire with different MIDI commands, that way you can control Millumin straight from Proclaim.
