Build a 4-channel HD video player for under $100

This is the cheapest way to get synchronized playback of 4 full HD video clips! This is also what I've been using to test out video switchers like the RØDECaster Video and the OSEE GoStream in my recent videos.

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

[pakozdiattila]

Simple, easy... and brilliant... thank you!

[ricardopontoncruz]

Excellent Aaron, Thanks for all yours videos

[avkans]

was wondering if you could help us to make a review video for camera., Could you?

[jacekkwiatkowski]

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 :)

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 😁

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!

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?

[KaneTreble]

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?

[theWINMEDIA]

funny, I did the exact same thing a few weeks ago.

[mrstewart]

How did she make her chat a separate camera angle?

[StreamTeknology]

You actually don't need to build anything. Just get one device that does the playback AND the split - which I covered here:
The rest of Aaron's video is spot on - you still need to create the 4K video with the four HD videos properly aligned.
