Interesting idea I would just take all the video make the 2x2 4K video in OBS and play it via hdmi to the matrix system. Skips the render and the video box. Still interesting idea 😁
Great tutorial! I thought about using Atema by outputting SuperSource 2x2 (4 inputs) and through HDMI scaler to 4K feed the signal to vMix or ecamm having 4 HDMI inputs. Only problem is with HDMI scaler to 4k - do you have any suggestion. What do you think about such idea? Best regards :)
I think I missed something - how was the switcher able to have a separate part of the 4K image in each input? Where is that SD card playing into? I seem to have missed the crucial bit!
The SD card plugs into the "Micca Speck" device. The "Video Wall Controller" box on the right hand side turns whatever it is sent into 4 separate HDMI channels, it's designed to be used with a, well, video wall made up out of 4 panels in a 2x2 matrix. Instead of monitors, he's plugging those into a video switcher.
Hey - purchased the controller you used, and can use when in 1080 mode (inputting 4k), but for some reason only get black screen (not even menu) when in 4k mode? Did this happen to you?
After a LOT of troubleshooting, looks like the outputs going into the ATEM don't want to take the 4k signal - when using another monitor it shows fine... not sure whats going on, doesnt look like you had this issue?
To close the saga for those following, the model I got from following the link outputs 4k to each of the 4 ports, so can't be used in 4k mode with an ATEM Extreme ISO in case anyone is trying the same...
The ATEM Mini won't accept a 4K input. The video wall controller I linked on Aliexpress takes a 4K input and outputs 4 1080 outputs. I didn't think there was any way to make it output 4K resolution, but it's possible there is a setting on it if you ended up with a slightly different version somehow.
@aaronpk yeah, tested the output and each output is 4k on my device (when in 4k mode), and 1080p (when in 1080 mode) but it downscales the 4k input to 1080 BEFORE outputting the 4 quadrants, so each end up being 540! Have put in for a return...
Nice hack, i can see myself using the same logic with NDI monitor app on apple TV able to display a 2x2 NDI source grid. Because it is a video player, how do you isolate the sound?
That's the limitation of this, best you can do is two channels. For this two person podcast I was testing with, I encoded each mic into separate right and left channels, and some video switchers like the ATEM Mini can pull those out as individual channels again. There's also a headphone output on the player so I was able to get a splitter from the headphone jack into two 1/4" analog outputs to go into the RØDECaster. But that won't work if you need three separate audio channels.
It's OBS outputting to an HDMI port that goes into the video switcher. So in the ATEM it gets luma keyed out. I actually have another video that goes into more detail about her whole setup here: Hiding a tiny UA-cam studio in the middle of our living room! ua-cam.com/video/twlJWIIR6ow/v-deo.html
You actually don't need to build anything. Just get one device that does the playback AND the split - which I covered here: ua-cam.com/video/YhJvW0--F8c/v-deo.html The rest of Aaron's video is spot on - you still need to create the 4K video with the four HD videos properly aligned.
Thank you Aaron! Your channel has been a wonderful enhancement to my understanding and testing of A/V setups.
You just make video that i’ve been thinking of, awesome
Simple, easy... and brilliant... thank you!
Excellent Aaron, Thanks for all yours videos
Brilliant!
Awesome & Thanks :)
Genius !!

I don't want to tie up a computer with that, plus the HDMI player is a lot cheaper than a computer!
was wondering if you could help us to make a review video for camera., Could you?
good job

funny, I did the exact same thing a few weeks ago.
How did she make her chat a separate camera angle?

I like having the extra raw 4K output from the player, but that's a cool box that has the USB player built in too
