Not THAT fussed about freeframe myself. It has some potential but I don't have much use for most of them, save for gaussian blur, panspinzoom etc.
I wouldn't mind if the most universally usefull effects (Blur, Thresh, reposition, resize, colour adjust etc.) were just built in.
I'd imagine Bart and Eddie are rather precious about Resolume (rightly) to collaborate and the same for pilgrim. I say they should do it themselves for Resolume though it would be a major, major rewrite i think.
