all I can say is it worked OK with my Studio Max 64. The files are so huge that rendering took a while but scrubbing through non-rendered files was flawless so no rendering needed till export. That's the huge difference between All-I and ProRes which, if I'm correct, needed no rendering. In any case, I've had more than one person tell me that it's not a huge bump in quality for the average person (me).Just confirming it's all working on the Apple side now, FCPX and QuickTime Player.
