“VDMX has been a big thing for D-Fuse. It’s the engine that drives our most innovative shows, laying out and compositing footage across multiple screens, hosting patch upon patch of custom D-Fuse development work. However, for our kind of theatrical shows, plugging a laptop directly into the projection setup just isn’t an option. We need video hardware to keep a solid feed to the projectors from early soundcheck to us walking on stage, we need to have a master fade control for our output, and we need to crossfade between our laptops to mix collaboratively. For year after year there was no solution to this, as with each laptop rendering all screens simultaneously the video format is outside of what the SD and then HD hardware can handle. What we needed was a DVI mixer. There wasn’t one, and so I made one.”
