I did a big festival last friday:
- unfortunately the "visuals" on the big screens behind the artists were done by the light guys using a grandma and video servers (pictured on the right hand side next to my screen)
My job was to switch between cameras and play trailers and sponsor logos on the LED wall which you can see in the back. It looks tiny, it was actually 20 square metres big. The festival had somewhere between 12.000 and 40.000 visitors...
My setup: MBP and MDD G4 running VDMX, V4 and an entrancer for the cams.
