#videofeedback — Public Fediverse posts

From the vaults: An excerpt from some video feedback experiments recorded in 1986, using a consumer grade video camera and television, with the soundtrack provided by an arpeggiated KORG Polysix synthesizer fed through a digital delay #videoart #vintage #DIY #videofeedback #synth

Working on some hybrid HD/SD video techniques. This required using many cables but the result is that if I have something with a transparent background I can add in some nice analog glitches and effects. #videosynthesis #glitchart #feedback #videofeedback

Happy #Groadtober 8th!

Brought the video feedback arcade game I'm working on with @allen to the playtest night at Wonderville yesterday!

The game is written in C++ using openFrameworks and Video Waaaves by andrei jay.

A multi-reduction-copying machine that can be found in every well-stocked household. (Mine needs a cleaning.)

One more test with a camera to monitor feedback loop. There is also a mirror involved. The camera can see the parts of the screen directly but some parts only indirect via a mirror.

Four images and some fragment shader code involved. The glitch effects are created by the camera monitor feedback loop; not from the fragment shader code.

#videoFeedback #GLSL

Images of light sources are superimposed. The result is rotating. In addition, a camera is pointed towards the monitor. The stream from the camera is superimposed on the rotating images. The rainbow colors from the frayed edges are created by the feedback loop.

#videoFeedback

Another camera-monitor feedback loop. This time, a glass cube, prism with colored transparent faces, is placed in the optical path between the camera and monitor. The rotation and the amount of complementary colors is generated by the fragment shader.

#videoFeedback #Clojure

A rotating color wheel is the seed of this animation. Superimposing this color wheel with the video stream from a camera pointing to the monitor. And some shader for tiling, rotating and false colors.

#videoFeedback
#glsl

Created with a camera monitor feedback loop. A thin strip of fluorescent plastic moves between the camera and monitor. The feedback loop also contains a fragment shader.

#videoFeedback #glsl

Another experiment with a camera-monitor feedback loop. The feedback loop also contains a fragment shader that deforms the image plane. In complex numbers: z^c.

After some seconds i move the camera slowly.

I think that the colors at the end of this animation are generated by the feedback loop. Not from the shader. There is no code to manipulate the colors in this shader. A color error in the camera-monitor system is amplified.

Video Feedback Machine Creates Analog Fractals - One of the first things everyone does when they get a video camera is to point it ... - https://hackaday.com/2024/01/02/__trashed-13/ #videofeedback #videohacks #art

A feedback loop made with an external WEB camera that is pointed to the laptop screen.

I used Hydra for this experiment. The essential part is this:
s0.initCam()
src(s0)
.colorama(0.3)
.blend(o0, 0.95)
.out(o0)

#hydra #videofeedback

this is fun and totally ahead of its time. like Forcefield or Danny Perez making a Backrooms video decades before either.

big shoutout to Headless Blood Idol for making last weekend's show available for download - takes me back to the DVD era of psychadelic DIY artifacts... check it out! :apartyblobcat:
