Expanding the Canvas at Summer Camp

This year at Teen Week at Tuscarora Inn & Conference Center in PA production centered around a center screen with LED bars “extending” the video platform.

While the setup was not, strictly speaking, a TripleWide this year, they did use multiple displays. Taking advantage of the multiscreen module in ProPresenter, they sent an output to the projector and a separate feed to the pixel-mapped led bars which extends the content to the left and right of the center screen. Pixel mapping control was accomplished with Enttec ELM, which took in the ProPresenter feed via NDI (network device interface.)

The projector was then fed off of a single output from my TripleHead2Go. They were originally using a second output of the TripleHead and a USB HDMI capture card to provide the clean feed into ELM, but the capture card proved to be too flaky to use. NDI has worked great, but involved a reworking of the mapping.


I asked the team about how they came up with the idea.

From Ryan with the camp:

“I wish I could say that there was some grand vision for this setup, but there really wasn’t. I knew that I wanted to dip my toes into pixel mapping, so I chose to pick upon on the stylized “S” in the camp theme logo for the placement of the pixel bars.

Video content is the driving force behind our lighting decisions so I’m always looking for ways to extend the tone set by video to the rest of the environment. Pixel mapping is a great way to easily blur the lines between video and lighting and bring content beyond the screen.”


The Projector is the Epson PowerLite Pro Z8000, projecting onto a 2.39:1 aspect ratio screen. The shorter/wider screen isn’t extreme enough to distort content in an ugly way but the smaller height helps with our limited vertical space.

The led bars are driven by Enttec ELM through an Enttec Pixelator mini and Plink modules. They ended up using 8 universes over ArtNet for this setup. The bars themselves are just WS2812b strips from Amazon that were then cut down into meter strips and adhered to 1m aluminum extrusions, also from Amazon.

Unfortunately this is not a very road-worthy setup, but it was very economical. There was a lot of soldering and troubleshooting. It was a major pain to get it all wired and working properly, but the effect is totally worth it.

There you have it! A great setup from a talented team utilizing technology in creative ways to expand a single screen via LED light bars.
