#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

@sstadnicki In this case, i change the color angle (hue) with the fragment shader. The camera sees its own image with a slight time delay, but in different colors. However, the change in the color angle was too large. When i convert these 1000 images to a movie at 30 fps, there is a lot of flickering.

These feedback effects, whether analog or digital, are difficult to reproduce. One must first insert color into the feedback loop and then change the parameters.

#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.

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)

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

#introduction

Hello everybody! We're Pixelflowers, a VJing duo.

"VJ" means we make live visuals over music (usually techno, acid house, industrial, ambient DJ sets). Here we share our weekly livestreamings, videos, resources and techniques about video art, news about dance music culture and technology, thoughts and ideas about how to merge music and visuals. We've been influenced by cyberpunk and hacktivist movements, intersectional feminism, psychonautics, and the sex-positive dancefloor culture we met in Berlin, where we're based.

We're two people, Flo and Pixi, but it's usually Pixi only who writes here. We're both non-binary queerdos with they/them pronouns.

We're looking for animations, video footage or static illustrations to play with: if you're willing to share your visual creations, get in touch! Check our pinned posts for details.

(CW: drugs, sex) Watch or download ~400 hours of our visuals + electronic music DJ sets:
