Sorry if I've lost the context, but... do you need to render using NSOpenGLContext? You can render frames of qtz using a QCRenderer, to an arbitrary size, e.g.: [[QCRenderer alloc] initOffScreenWithSize:NSMakeSize(pixW, pixH) colorSpace:co composition:composition]; have fun Rua HM-- http://cartoonbeats.com http://haszaristwocents.blogspot.com http://myspace.com/haszari http://last.fm/music/Haszari

I want to render my composition at some arbitrary size (different from that in which it's displayed). I can't quite figure out how to create an NSOpenGLContext offscreen (ideally on the GPU) of a specific size. I can see how to make it full screen, or with no specified size, but neither is what I really want. Any idea what I should do?
