TansFeed

pxn_tansfeed is a realtime feedback and glitch plugin made for live visuals. I made ages ago for Netaudio gig but now i optimized and used in Lithuania.

here are some screen-shots made with TansFeed:

new vdmx with new pxn

today i made a really untrendy, glitchy and noizzy “pxn plugin” for my upcoming show. The name is ´kill that f*cin pixel’. Nothing else just modified ´core image´ code with feedback and a small offset. The modification means, the original ´core image´ code has a certain function, but after playing a bit with code i got more funny result.

 

Video Noizz-a very useless tutorial

Its not a normal tutorial, not producing any usefull thing and maybe sometimes the result is unexpected, but a good basic feeback video noizz, from PXN.

I normally check my blog daily, and  i can see whitch was the search engine terms what the people used to find my site. In the last time i found this one: quartz composer video noise generator, 3 or 4 times. So i decided to share my solution here.

We are going to use a feedback, some special blend modes, and over-adjusted opacity, and basicaly thats it.

The only one special plugin what we need is the kineme GL tools, its a free collection of very handy  plugins for QC (10.5,10.6). You can donwload from the kieneme site.

After playing  bit with the new plugins, we have to search for Kineme GL Logic Op. Its a macro patch so will render out what is inside in the macro patch. But as a blend mode it needs something under, i mean an under layer, so we have to make a bit more complex thing.

We place a sprite (with the right size) in the Logic op and the logic op in a render in image. We put another sprite inside in the render in image as well, this will be the under layer as i mentioned earlier, and of course a clear under. So this is the render in image.

The next step should be to publish all the two sprites image input (the one in the kineme GL op mode and the other in render in image). So both has to be published outside render in image. And a practical thing to publish the input of ‘gl op mode’ (the mode one).

Now we need some other nodes as Core Image Accumulator (as the grandmaster of feedback), ClOpacity (to control the feedback), and an image Texturing Properties (to transform a bit the feedback). And a sprite at the end, and of course a video source (i used video input).

Lets make the connections. And its done, well the test blendmode can be ‘Xor’. Noizzee, but what about some nice lines, instead of noizz. Thats why we need the ImageTexturinProperties, for example lets put the ‘MatrixTranslationX’ value of the Image Texturin Properties, higher then one. We can play with the scaling values and with the rotation as well.

Final adjustment:

If the result is to much flashy, then we can get back a bit, switching ON the ‘Disable Color correction’ option of the ‘render in image’ (alt+2).

Lets play with the opacity, blendmodes and maybe some more nodes we can connect to the output of the ‘core image accumulator’ , but thats easy to try.

I tested this composition as an effect in VDMX and works perfectly, the speed is really ok, and i used last weekend during my performance at the Satta Outside festival. I will write the festival review soon.

meanatime i wrote this tutorial i got this random QC interface glitch, so i will share it. Dont ask how:)

pxn is going to lithuania

Iam invited to play a 3 hour long vj set at Satta Outside festival  in Šventoji, Lithuania. This year the thematic is glitch, so i will make a dedicated pxn set. I decided to use this time VDMX, so iam trying to involve all my pxn fragments, as effects and as generators. The other ‘thematically’ invited artist is Rosa Menkman.

here is a small preview directly from vdmx:

here+now

pixelnoizz, *spark, an empty media card and a glitch machine:

when its here+now, you’ll be part of it. an experimental performance workshopped as part of visualberlin festival 2010.

this will be the first time, i will use my ‘PXN‘ package, and it fits in the original concept.

so what is this ‘PXN’ thing?

This is a set of plugins, effects, transitions and generators. Based on really easy transformation of glitch, feedback, blend and mask-modes. And of course my G_P_G  is a decent part of it.

The basic concept was to make very easy performance without many contents, perhaps a live camera feed in to my face or just one video loop. And using 30-40 filters and combining them with blend-modes and feedback. I think this kind of combination is enough for a performance, and the performance will not less than one performance with hundreds of well prepared video loops.

And yes, we met with *spark during last LPM festival, we spent some time together and with Vade as well. He offered to make something with a wireless photo camera and glitches. As my stuff is really supported by Vade’s V002 its in reality a cooperation between us.
