Parameter supervision works in FCPX, with the caveat that the UI isn't properly updating at the moment. We have a bug on it, but I don't know its current status off the top of my head. Basically, if you select another item in the FCPX timeline and then re-select the item with your filter applied, do you see the changes?

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com I should clarify that if you do what I suggest below, you don't need any temporary buffers. Just texture your quads with the input texture and they're automatically drawn to the output texture when you do any normal drawing.

So lets say you have an input image that's 640x480 and your output is also 640x480 and you want to copy the area of the input that is from (25,25) to (50,50) to the output at, say, (100,100) and (200,200).
