Advanced Tools in IMovie
I am working in IMovie 10.1.1 and am trying to use picture in picture and green screen. When I follow the instructions to activate advanced tools I go to preferences and there is no tab to get to advanced tools the only thing it shows is "slo mo clips", "photo placement" "clips", "transitions" and "theater". My previous version had tabs that included "General, Browser, Video and Fonts". Why doesn't the new version allow me to access the general tab and enable advanced tools????
