video-out

providing visuals from 5pm to 11pm was somewhat daunting given i’d pretty much chucked away all my random-gig vj clips a year or three back, they wanted it all america’s cup themed, and oh: 1080P.

well, nothing like a bit of fear to rise to the challenge: rocked it, aided and abetted by
- cuts culled from 200GB of america’s cup footage downloaded from their broadcast server
- a few choice compass rose type animations
- some custom quartz composer patches
- a live stills camera
- the dvi mixer pumping out 1080P into their system, but the laptops only working at the (good chunk lower) actual resolution of the screen.

wish I had got a photo of the big americas-cup cuts glitch mash-up i had going on, but then again, it was all about how it moved with the music.

and how did those live graphics make it to the screen? i sat down and took the idea of *spark titler from sheep music and remade it as a fully fledged cocoa+quartz composer application. the idea being it can’t muck up: animation designed to gracefully transfer from state to state, participant names pre-filled in a drop-down menu, no mouse cursors on the output, text fields that commit their edits on pressing take… the little details that make-or-break a live application. oh - and it exports its title animations as quicktimes for integration with playback pro.

as part of the rhythms and visions event, a day of workshops was organised. los angeles visual artists - lava had the morning, and covered the past and present of ‘visual music’ works. mike, matthias and i had the afternoon, which we nailed the four hours precisely with a tour through the d-fuse oeuvre and a journey through our particle production process. the latter was my main contribution, and its a tricky balance to give: lots of really cool stuff — shooting, taking crops, building abstracting effects — but with what can reduce down to a sea of noodles and buttons. pretty happy though, good feedback that the thread was there and it all tied up: people got it.

in town for the ‘what is live’ symposium, and there’s also a 10 screen surround audio-visual environment round the corner? bring it on.

the rml cinechamber is a fantastic thing. yes they have technically assembled such a thing, but what excites me is their focus on content for such an environment and hosting artist residencies to develop that content in-situ.

signal’s live show — pictured — was compromised to the extent they held a free gig at the close of the festival with the visuals resolved, even so the simple effect of the spectrum analyser stretching far around you was eye-opening. the monolake show justified the ticket and then some. while not my aesthetic taste per se, it had moments of arresting majesty, whereaudio-visual sync combined with some immersive twist and you really weren’t sure where you were any more.

cinechamber is a long term project remade for 2011 and (re-)debuting at club transmediale, and so the hope is to catch it again: the overriding thought i kept having was that there finally is the true environment to actually experience the 11,000x1080px ‘dot from the void’ motion graphic piece d-fuse produced a summer or two back.

straight on the heels of the ‘holotronica’ onedotzero d-fuse performance, to dresden for ‘cynetart: international festival of computer based arts’. after the experiment of holotronica - more diversion and distraction in the end - this was the return to the real thing, and the chance to up its game with a refined set of footage.

the festspielhaus turns out to be an immense room, but moreso their technical production turns out to be impeccable. setting the staging for performances like particle is always tricky as the immersive effect we are after for the audience is so dependent of the geometry of the space, and at cynetart it all came together. the projection onto the front screens was able to fill the front screen fully while bathing the whole seating area in the spill-through projection, yet without the audience being blinded by that projection’s source, looking down the lens. rigged for a ‘trip’, rather than as cinema.

check the attachment too, the whole space was quite special, not to mention cycloid-e behind us.

there is now a mac pro in china running DFD, something that has been consuming my time for a while now. the roadshow d-fuse have been developing is our first big foray into automated dynamic content, lighting and audience interaction, and so without us being there for every gig holding it down with a hacked-up vj setup we needed something that you could just power on and the show would start. and so d-fuse/dynamic was hatched, a quicktime and quartz composer sequencer which reads in presets and its input/output functionality from a folder we can remotely update, and essentially just presents a “next” button to the on-site crew.

what i think is particularly novel about DFD is it was designed to output a consistent framerate, rendering slightly ahead of time so the fluctuations in QC and QT frame rendering are buffered out. i’m not sure is the effort/reward of this was worth it, but it will be an interesting code base to come back to and re-evaluate.

for the roadshow, it is playing out any number of four sources at 1280x576, including the generative, controlled by iPads in the audience and LED balls on stage, audio-reactive core of the show, sending the central 1024x576 to the main screen, driving 10 LED 72x1px strips from the remaining 576x128px on either side, and sending DMX back out to the stage lighting and LED balls.

big thanks to vade, luma beamerz, and memo for helping me one way or the other grok anti-aliased framebuffer rendering.

having spent much time i didn’t have trying to get 64bit QTX giving me openGL frames at QuickTime 7 efficiencies, life saving thanks also to vade and tom for v002 movie player 2.0, for which there is patch back with them giving it the ability to play the QT audio to a specific output.

lastly, a perennial thanks to kineme, couldn’t have gone this direction without knowing their DMX, Axis Camera, and audio patches were out there.

i’m not sure what to do with the code at the moment. it was made as a generic platform, but its current state is still very much tied to that specific project. or rather, the inevitable last minute hacking as it hit china needs to be straightened out. it has been made and funded as a tool for d-fuse to build on, so that needs to be taken into account too. in short, if anybody has a concrete need for such a thing, get in touch and we’ll see what could be done.

the iPad-screens interaction isn’t even half of it, though. the project is to be a roadshow travelling through china, a modular setup of stage and staging reaching out into the club. two ‘hero’ videos with dance choreography and interactive props (hello LED balls), a video feedback piece, a live drawing piece, the backbone of the evening as the iPad interaction and audio-reactive graphics, all feeding out onto the mains screen, duplicated onto any in-house video system each venue might have, with LED sticks extending the video canvas out from the stage and video controlled stage lighting effects.

…it makes for a nice diagram.

another work-in-progress update for the *spark d-fuser aka dvi mixer project: here we have the v1 pcb design, parts specified, plans drawn, and — with shawn multimeter in hand — the leg-work translating that into something that works. the real announcement here, though, is this: i will be presenting the project in full in berlin on the 12th june, so expect to know a lot more about what, when and how around then.

aaah, a proper theatre. well resourced, good tech crew, and a lovely auditorium for the audience.

its been quite some time since november and nothing visible has been happening. this is a quick post to say that stuff is happening behind the scenes, albeit with lots of delays caused by my spare time being completely out of sync with people i’ve been trying to get things going with. but now the momentum is back, and here shawn bonkowski and i are choosing sliders from the seemingly limitless selection on offer.
being trained in product design and loving this book, i’d have said i have a fair understanding of how much work it can take to transform a prototype into something suitable for manufacture and the real world. but i have to admit, this has taken far far longer than i expected. though now, i think, i can say that the controller is falling into place: still far from having a final, manufacturable, design, but the road to get there is clear and doable.
