I thought it would be cool to make some VJ-style visualizations to go along with music on a matrix LED sign. I finally got a quote for one from Aliexpress that can take HDMI input and it was like $900 before shipping. It seems these are a bit more costly than I was expecting because there is a "sending box" that takes HDMI and converts it to some Ethernet protocol. That goes to a bespoke card, and that card is what all the smaller matrix modules plug into to make one big display. Those components apparently are quite expensive.
So I made this little tool with the help of AI to play videos with the look and feel of the real thing so I can start making my visualizations right now until I figure out a cheaper solution. I got some advice to check into neopixel matrix displays. Haven't dug into that but maybe I can get video to play on those from a raspberry pi or something directly, avoiding the need for a sending box.
I made a little web app to simulate the look of playing a video on an LED matrix display. e.g. https://files.catbox.moe/ddequo.webm
