I have a Kona 10bit RGB Log project in FCP. I'm bringing it to a post house to do a layback to HDCAM. They told me to output a piece to test... a Kona 2yuv codec conversion .mov file. I made it. Gave it to them. They said it would open up in their timeline fine (no red render lines), but that it wouldn't play out of their Kona 3 card without. They suggested I give the a ProRes version of the project, but I'm still in FCP 5.14 land, not 6. I just updated my Kona plugins, could that be the issue? Any ideas? Why on Earth wouldn't their machine play a Kona 2yuv file properly? It seems so simple. Hmmm?
