If you're thinking of using Qlab this is what you're looking at. These are my corrections notes JUST from the plot. Zoom in to the A4 pages! 5 times the amount of work than updating dvds - tedious and time consuming. The 2Ghz Intel Mac minis were only just barely able to do a cross dissolve, pathetic! Still, if you have to hand the av over to another operator, this is the way to do it. A BIG loss is no live operation, its all automated.
