Large scale media for Showtech Berlin 2011 done with Blender


Mikko Saari send us a note about his recent project he worked for the Videlco booth at the Showtech berlin 2011 exhibition. It was an 7300 x 1000 pixels animation projected onto a 180-degree semicircle canvas.

For this presentation he used Blender as a 2D animation compositing system like After Effects. Mikko used Apophysis and Flame together to quickly generate 4k resolution fractal backgrounds. Over those he placed company logos, product pictures and other pre-made material. Different color drawmodes were used to blend them together.

Blender's node editor was crucial in order to crop and scale those fractal backgrounds, create color correction, glow - effect and vignetting if necessary, and most importantly: remove rendering artifacts with bilateral blur, so that compressing this massive resolution won´t cause the file to eat too much HD.

For logo positioning Mikko stated that Blender's new import image as plane add-on was very helpful in positioning logos and graphics. He used the VSE to cut all animations together and export the finale film.

A Picturall Octo - media server was than used to send the video feeds to three video projectors which filled the 180-degree canvas.

Mikko has been working with looping background animations and Blender for years, and is willing to work as assistance or even producer with anyone who needs assistance or medias for installation.



  1. W00t! I can do this with my humble computer, too. Please contact me about two centuries before your event, and I will do it ;)

  2. tweety are you shure you can do it with 1 computer? you need three because you have to project it with 3 projectors. in 2009 i was working on the event "House of Lange" for an event wich took place in L.A. CA. we got 5 projectors and 5 computers to create a 9meter wide screen..... the best graphic card cannot handle 3 projectors in respektive HD resolution, i believe.

  3. Hi Alex, and tweety,
    the source media was created with only one computer. you can easily cut render times ~1/3 if you do things right. :) however, to composite i used 3 computers - mainly because VSE is "just a bit" slow with resolutions like that.. :( and extra gear was only because we were on a pretty tight schedule.

    and no no, you don´t need that many computers to playback this! you can easily playback this with one media server.

    -Mikko S.
