As promised earlier this week here is my Jitter Rutt Etra video synth stripped down and prepared for general consumption. Try experimenting with the wet/dry mix for some interesting feedback action along with the zoom and rotation values, angles like pi divided by integers lead to some interesting patterns. Get stuck in.

Since my last post I’ve been working on a few things, details of which I hope to post soon but I’ve spent most of my time working on my Rutt-etra inspired jitter/open-gl video synth. This along with a database youtube video harvester I wrote in Python will form a major part of my next piece I’m hoping to submit to the 2009 conference. I’m aware that it’s not entirely an original idea to build a software version of the famous 70s video synth and I have to admit to being inspired by vade’s work in the same area.
As well as the version of the software developed for my own use I’m working on stand alone and max patch versions for distribution to interested third parties. I’m pretty pleased with the vsynth, it basically displays an input video on to a set of parallel lines each of which can be deformed, point by point along the line, with the luminosity of the image controlling the height of each point. On top of this it does some pretty open-gl feedback and a nice feature I just added is to allow the mixing of the feedback with the source footage to give some pretty pyschedelic results.
Although it’s a bit of a cpu hog it runs fine on my old 1.8 GhZ single-core laptop as I went to great pains to move as much of the process on to the GPU as possible. I’m hoping to post a first general release of the patch by the end of next week so for now you’ll have to make do with some screenshots.
