sound is amazing. one of the coolest sounds I've ever heard, especially considering its source. one of the neatest videos on youtube in my 12 years of watching
There is something amazing and beautiful and incredible right there, in mathematics, underlying our reality. It's so mindbogglingly cool that this comes out of a simple feedback loop. I've not seen anything more fundamentally beautiful.
Great! I spent ages recording brilliant trippy patterns like this in my misspent youth, then setting them to my favourite dance tunes. Try dangling things in front of the TV screen then completely the feedback loop - also very entertaining.
I used to make these with an old video camera and a tube tv. They were so cool! I got mine to the point of a blob of light in the middle of the screen that I could literally push around and deform at will. That was like 30yrs ago. Still cool today!
I really enjoyed this presentation. Both the audio and video were mesmerizing, at low volumes I was completely astounded by the sounds. I’m very into avant- garde synthesizer music, this is a different kind of beauty.
the shuriken-like figure was so cool. also, that portion of the screen bleeding out from the circle sometimes reminds me it's real analog feedback and makes it even cooler. so sharp and well-defined. really, really good stuff on your channel!
You have very good control of your video feedback. Analog feedback with vintage equipment is beautiful the way it flows. I liked the audio too, even the glitches worked. I achieved control with my own video feedback by using a computer to control motion.
This is brilliant. I remember messing about with an old VHS camcorder producing similar stuff years ago. Didn’t quite get it looking like this, but yeah. Also LOVE the audio. Nicely done.
Wow. I tuned my AM radio to around 150KHz and placed it on my laptop with the antenna next to the screen. I was able to make my own sort of interactive audio with this. It's very sensitive to the tuner and the position of the radio, and there's inevitably some interference as well. There's also a droning frequency due to the refresh rate of the LCD. Most of the audio comes from horizontal features. That's because even though LCDs don't scan like CRTs, the data probably gets sent in a scanning pattern leading to horizontal features producing tones in the audible range.
I came across this circular period in feedback also. Thing is, you have to have certain cameras and a certain period of television to work, because modern flatscreens no longer generate this style of circular effect.
Hi Japhy, I'm a video producer at Newsweek and I want to use your video in one of our articles. Can I have your permission to use your video? Thank you!
I love this and am mesmerized and hypnotized by it. I can't stop watching it. Wish there was a "visual synthesizer" where I could no only play it for the sound but also for the visuals like this!
A number of people have purchased the rights to use this video from me in the past, so it's usually not for free. But, if you really don't want to pay for, I could send it to you.
Can you detail how the audio was generated for those who aren't as savvy in how to process an analog video signal into something as cool-sounding as this?
Sure. To put it simply, an analog video signal is nothing more than amplitude over time, just like an audio signal. It's just a varying amount of energy that eventually moves a speaker cone in and out, or varies the brightness of a spot that moves extremely fast on a TV tube. So, it's possible to record the video signal by plugging it into anything that can record an audio signal. (You can also plug an audio signal into a TV and watch it) The only problem is that, with the video signal, come the parts of it that are used to position it properly on the screen, mostly notably, a 60 cycle buzz with upper harmonics. So that needs to be filtered out as much as possible. I don't remember exactly what I did in this video in regards to the audio, but just try it yourself and play around. : )
@@japhyriddle I enjoyed the video! Very powerful to me knowing the nature of psychedelics this is oddly familiar ;-) Even the sound at a lower volume! This kinda explains what it feels like! Also I think a bipolar capacitor, or resistor is all that was needed to pass off audio!
Nice. Looking on youtube before, they didn't really have any video feedback things as good as what I had gotten myself with non-digital camera and TV, but this is categorically superior, getting the center to be so slow and sometimes motionless, great work. What is the audio? Makes me want to watch with binaurals/isochronics like the old days
wow.. I wonder if this also works with a digital camera and a computer screen..? I'd love to generate these myself! some of these patterns remind me of mangekyu sharingan from naruto xD .. really pretty!
Yes, you can do similar effects with newer digital equipment. There will be some differences of course. Most likely, a very noticeable difference will be a delay between the camera and the screen resulting in further delays on down the recursive rabbit hole, which is not a bad thing. I had to look up what you were referencing. And yes, I see the similarities. There's a great book of Mon designs published by Dover called Japanese Design Motifs if you want to dive into that world. : )
Outstanding !! But is there a way to see this with less digital quality reduction ? I mean, I suppose the original has to be "cleaner".. when I watch it in fullscreen it gets blurry and "pixelized"... I just want to enjoy it as much as possible ! thanks a lot :D
Well, there's no way to stream it online much cleaner than this due to the current compression algorithms, but you can download a 3GB+ version here: drive.google.com/open?id=178Z2GhYiUpZ2hJ_MyiXOTjxgxEzMpCGy
Hei, thx for sharing these great video feedback, could you tell me which type of device do you use, the type of camera and tv , their frequencies, please? the outcome is very dynamic, bouncy, i'm curious about the type of electronics. I made also VF but rarely had this dynamic movement, generally i got more smooth movement for the same type of patterns. thx!!
Hello, are you the author of this experiment? I am an art student and am researching some video feedback images as reference, I had already seen this experiment once at the university and now I found it again. I am going to produce a short artistic video based on this concept of feedback - I don't have it fully planned yet but I would like to know if there's any chance I could use a few seconds of this video in it, no more than 5. If so, tell me how I could credit you! This is a project with no funds involved, I'm making 5 experimental videos each one with a different concept for its construction, only for experience and maybe portfolio. Thanks for the attention :)
+Lorena Ramos Yes, I made this. You can absolutely use this. Any duration you want. You can credit me however you'd like. My name is Japhy Riddle. Thank you for asking and taking interest. I hope your project turns out great. Cheers, Japhy
Hello Japhy, love the video! I used to experiment with video feedback in high school, but was never able to get it so precise - great work! I saw that you gave someone permission to use part of this video in one of their projects and wanted to ask the same :). I'm a hobby musician and was hoping you might let me use part of it for a music video that I'm making (no profit). It would be greatly appreciated, and of course you would be credited as well.
The sound was made by plugging the video signal into the audio input. I ran it through a handful of filters to make it a little more pleasing and interesting, but it's still rather harsh on the ears.
this is amazing. what did you use to generate the audio? im looking to do something similar to this myself and am unsure where to start. ultimately im hoping to create a feedback loop between both audio and visual sources, where the output of the audio either modifies pre-existent video or generates visuals, the output of which is then mapped to the parameters of a synthesizer, creating a full loop.
@@Yizak not yet been busy, but I'm thinking about learning Max MSP which I'm pretty sure could be used to setup something like this. You can do just about anything with audio or visuals with Max
It was years ago, so I don't remember all the filters I ran it through. But, the method for getting audio from it just involved recording the video signal as audio. You can just plug analog video into an audio input. It's very buzzy though, so it needs to be filtered to make it listenable. Noise and buzz reducers could play a big role.
RF stands for Radio Frequency. Rather than the dedicated video input, a video signal can also be fed into the TV basically where the antenna connects. The video signal must go through an RF modulator first to transform it into a signal that appears to the TV like a channel 3 or 4 signal. If you have a TV with an analog dial, you can tune slightly off of the station and introduce noise (video static).
(I have a few CRT broadcast monitors, but a 70s video camera sounds pretty unweildy to ship. I could definitely find a period conrac monitor, if I wanted :D)
The camera I used is relatively small and light. It's a consumer product, not a huge studio beast. Shipping shouldn't be much of an issue if you seek out something small like this. The 3-tube color cameras weigh a lot though. I found this particular camera at a thrift store for $20. I don't think the camera being tubes really matters that much to be honest, anyway.
wyatt8740 Ah, yes. That's understandable. The black and white ones are fairly plentiful on eBay. The three-tube color ones are getting really hard to find for reasonable prices though.
@@japhyriddle Thanks! And you rotating the monitor instead of the camera gave me the inspiration for some modifications I'm currently working on. As soon as the USPS finally gets stuff here I'll be able to complete this part of Phase II.
that's the way to do it! The noise introduced going RF makes the feedback so much more intricate and lace-like. Check out b&w feedback I did and then colorized. Didn't have the ability to go RF unfortunately ruclips.net/video/DG0-OANvFek/видео.html

Aw. Thank you for your kind words. You may be the only person who likes the sound. Most people can't stand it. Ha ha.
@@japhyriddle I love the sound too. The combination of visual and audio in perfect sync is so hypnotic, the whole thing is a work of sublime art.

It's so crazy seeing PilotRedSun commenting on this video. Love your vids man!
I totally agree with you! Awesome images and audio!
There is something amazing and beautiful and incredible right there, in mathematics, underlying our reality. It's so mindbogglingly cool that this comes out of a simple feedback loop. I've not seen anything more fundamentally beautiful.
Look up Fractals and Mandelbrot sets if you want to understand the epic yet amazingly simple maths behind such imagery.
@@Robin.Burke-Optical_Collusion Cheers, yes of course, I've played with fractals a lot, and wrote a couple ways to render them already :P
something "underlying our reality" huh?
Great! I spent ages recording brilliant trippy patterns like this in my misspent youth, then setting them to my favourite dance tunes. Try dangling things in front of the TV screen then completely the feedback loop - also very entertaining.
you call that misspent? : p
every frame of this video would make a sick t-shirt

The fact that PilotRedSun is the top comment on this should tell you everything you need to know, it's like being blessed by Weird Jesus
Beautiful and inspiring, thanks.
absolutely mesmerizing.
This feels like one of those 1970s Sesame Street skits that would be notorious for being "OH NO SCARY"

Sure. Go for it. Please send me a link when it has been published.
Japhy brought me here. Amazingly wonderous video. Fascinating article on consciousness.
Reminds me of cellular automata
I can see that.
Kubrick could have used this in his ending of 2001
If Kubrick knew about this, especially with him being a numberphile and mathematician, he would be all over these clips in his movies for sure.
bernard lodge did it first
They were actually going to use video feedback as a concept for an alien creature that would be featured at the end but decided not to.
Fantastyczne! Dziękuję!
Has anyone tried putting the feedback itself put through the same process that generated it, in a sort of recursive series?
I'm not sure I understand the question you're asking.
I love this and am mesmerized and hypnotized by it. I can't stop watching it. Wish there was a "visual synthesizer" where I could no only play it for the sound but also for the visuals like this!
