It seems like you must have steam, and the games that you make movies with are also in steam... I'm not sure how it goes with, or if you can, import other files... I'll have to look more into it.

The first thing I wanted was a green vortex opening which seemed harder than I thought.. then I wanted what I had there to use the fluid simulator to melt down showing that the Grim Reaper had disappeared.. couldn't get that to work when I wanted either. So I just stuck my text on top and Viola! lol
