Resolume Forum

Hello!

Somewhat of a Noob here so please pardon by inexperience!

The Goal: To have (3) 16x9 sized LED walls all built next to each-other together to form a long 7' x 36' wall on the floor.
- We want to be able to project Power-Point to the outside 16x9 builds while keeping the center 16x9 build for graphics and creative background. Then when needed, switch to a signal that will feed the entire 7 x 36' wall for graphics and taking down the power-point.

I understand that with Resolume Slice we can map LED screens to any "projection map" we would like! In my research it seems that most creators start with a 1080p comp in Resolume and then build the individual walls within that 1080 comp? In our case it would be one large rectangle.

My LED wall supplier does not have Resolume so its up to me to figure out. However his concern was that the hardware would be the bottle neck.

The gear he has:
7 x 36' wall is 2,688 using 3.9mm panels which is wider than HD. He doesn't think that any of the Novastar processors can output that wide of an image. ---> Is this true? How is this done for VJ's?

He has multiple Processors to work with: Multiple Novastar VX6S's
3 VX4S, VX4S-N, Chauvet Drive43Nova

Our workflow would be PC running Power-point --> capture card into Resolume PC --> Then would it be a single HDMI output into one Novastar? How would we get the content to be viewed on the the large 7 x 36' Wall?

Many thanks for the help

Hey River,

So I'm not an LED Tech that has installed/configured multiple walls in my career, but until someone else with more experience chimes in, maybe I can point you in the right direction.

I need to say this, hopefully without any salt. If your LED provider is physically assembling the wall for you and supplying/setting up the processors, then most of the technical work is going to be his responsibility. He should provide you with an output guide for how he wants content delivered to the walls, and it should be clear to you at that point how to deliver it to him, by making use of Arena's advanced output settings, and as you mentioned, different slices.

If you need a visual, and/or more output mapping explanation: viewtopic.php?t=19476

If you've been left with the task of programming your processor(s) for this job, then it's going to be more involved. If I were you, I'd do my research on those processors or find someone who knows them well. I've used Novastar processors before and I like them, but my knowledge is limited on those models. That being said, I'll help how I can, but there may be some gaps in my knowledge.

What you're attempting sounds feasible with the VX6, and certainly with multiple VX6's cascaded together. A quick google search shows that the output's maximum width and height are 4096px. Much wider than the supposed 2688px that you will need. I would look into Nova SmartLCT software. If it's compatible with the VX6 series, it should be pretty straightforward to map that all your frames.

I'll briefly walk through what makes sense in my mind, but please note that I'm going off the assumption that your LED processor can accept a 4K input.

You could set your composition to 5760x1080 (3x the width of standard HD) and set three 1920x1080 slices all next to each other in your "input selection" tab in Arena's advanced output settings. Then, in the "output transformation" tab, map your output slices however you need to based on the output guide that your LED supplier hopefully gave to you. If you don't have a guide/map, the simplest way to do this in my mind is to send a 4K output into the processor, with your three 1920x1080 slices arranged into quadrants of your 4K output. In other words, top left quadrant would be "slice 1" or the leftmost 1/3 of the ultrawide video wall, second quadrant would be the middle section, and third quadrant would be the far right 1/3 of the wall. You'll have a blank quadrant in your 4K output at the bottom right.

Assuming your processor can accept a 4K input, and your frame/panel mapping was set up to receive in this fashion, you should be all set to start composing your content in Resolume as you see fit. The slice transform tool can help you easily throw your PowerPoint content on the left and right sides as you described.

Hopefully this helps a little.

novastar vx6s can go over 1920x1080 px but the total of pixels must be the same of 1920x1080.
If your ledwall is 2 mt high (512 px) and 10 mt wide (2.560 px) you can go with vx6s.
