The problem: Display four computer screens on one projector.
Hardware HD video mixers with VGA inputs are too expensive and employing a minion to switch between VGA channels manually is impractical. The obvious solution to display multiple screens simultaneously or in sequence would be to use a video mixing software. But video capture cards to get the video signal into a computer have their price point as well. We all (still) have ethernet though, so VNC to the rescue. (more…)
In this short blog series I just wanted to get out some aspects of the live coding band Benoît and the Mandelbrots, as we are pretty bad at documenting and sharing our efforts and insights. Lots could be said about musical approaches, but I solely will write about the projections first, as I created most of the systems and so I feel confident to write about it without discussing it with the other ’brots.
I ventured a little bit into Mac video plugin programming. I wrote a Python script to easily convert/compile a GLSL shader into a FxPlug Plugin for use in Motion. You can find GLSL2FxPlug on GitHub. I used it in this Teaser for nil#3 Party.
Speaking of nil#3, here is a nice recording of Visuals I did for Plüderhausen:
I did my first big-screen visuals show at Stadtgeburtstag Karlsruhe for Benoît and the Mandelbrots. As I was also playing with the band I had to script all transitions and trigger them when appropriate.
Throughout the history of the world wide web many techniques were conceived and used to add audio to a web site. Some of them only allowed web designers to embed static audio files into their sites, a very questionable practice if it’s used as a background track. Some of these techniques have practically already died out along with the infamous <marquee> and <blink> HTML tag.
