anyone else do fun stuff with analog?
(please be careful watching if you're sensitive to flashing light!)
I just set up my first double feedback loop!
Camera pointed at CRT HDMI direct output -> conversion to RCA -> dirty mixer -> CRT (Feedback Loop 1)
+
PC Monitor -> Windowed projection of HDMI to RCA conversion -> dirty mixer -> CRT (Feedback Loop 2)
Same Camera USB Video Capture direct to OBS pointed at CRT & recorded (Sum video)
it's fun to create trails by doing stuff between the tv and camera
(flashing lights warning, seriously)
i came across this video a while back, it's a very cool effect.
i wonder how to do this stuff, it seems very complex with this one. some kind of custom circuitry? (last time i tried to do a circuit, i fucked it up horribly...)
oh wow that's VIVID
When I made the second devlog for the game I'm currently working on, I looked into how to do some digital-only datamoshing. Unfortunately, I wasn't able to find anything in particular that worked well for me but I ended up figuring out a few ways to corrupt the video in interesting ways using ffmpeg filters.
#!/bin/bash
ffmpeg -i "2023-12-02 16-38-39.m4v" \
-vf scale=1920x1080 -bsf noise=4000 -r 30 -f mpegts \
-c:v h264 -crf 31 -preset ultrafast -tune zerolatency -an \
output.mp4
Unfortunately, the website that I learned this from has since been reorganized and the page isn't up anymore. It's on web archive thankfully.
