Desmedt, who is based in Bruges, Belgium, drives the video show using software from d3 Technologies. He runs it from his custom-built PC. "You can't do it on a Mac, it's not powerful enough, they're so behind on all this stuff. You need something on steroids," he said. His multicore setup uses a backplane architecture to get the performance he needs when, for example, layering three or four sources of uncompressed video.
Having all the video content easily accessible via the flash array makes it possible to tweak the show on the road as the artists demand.
When U2 wanted to change something in one of the set pieces in Boston, "I immediately went in there and made changes. The whole project is living with us, and that's what makes it really quick," Desmedt said. "You don't want to be in a hotel room downloading ten gigs for a video clip. We try to do everything locally, and carry as much with us as possible."
