Evolved Video feedback

with 3 Comments

Here are a few images I created with (virtual) video feedback.  Many of these were automatically evolved based on their spatial-frequency content.  Others were generated interactively, with various different interfaces.  Really, this stuff is much more fun when moving, and particularly when it’s interactive…

I hope these are enjoyed by anyone who happens to stumble across them.  At some point, I should update with more images, some usable software, video and better explanation.

    I like the video feedback images. You could play with these by dropping a series of screenshots into photoshop layers – then set them to play through in sequence and save as a gif. nice quick, easy way to explore and manipulate their movement. Your own virtual “Flicker book o’ Video Feedback screen shots”.

    I am looking to get into video art for music so i’m new to this. the images you have are superb. they’d look good animated like you say.
    I’d like to know what software you use ?!

      I write my own software… I’ll make more of it public in the (hopefully near) future, as well as writing a bit more about the techniques used etc. I’m gradually developing tools to make coding stuff like this easier without having to get too bogged down in all the tedious details (hopefully still retaining control for those times when the details matter), and I’ve started doing occasional workshops which aim to be accessible to people with no prior programming experience. I have one coming up very soon in Brighton (England); if you happen to be in that neck of the woods, you might be interested: Evolutionary Live Coding Workshop @ Phoenix Brighton.

      I have released an iPad app based on a similar process, which is by far the most satisfying incarnation so far; see my more recent ‘Fractaleid‘ post. I plan to port that to other platforms, make other variations, and (relevant to you since you are interested in making video art) add the ability to render video.

      The software I used to make the images in this post was made in either Java or Pure-Data (pd). Pd is a kind of visual patching thing originally for computer music but also has various plugins for graphics (in particular, GEM). Processing is something you could also look at if you’re interested. These days, for things like my live-coding workshop, I’m using JavaScript / Three.js. Thee.js on its own might not be the best thing for a beginner, though.
