Hi, I have a 1440x1080i project that was edited in Sony Vegas. It will be color corrected in FCP, so I installed the DNxHD codec on my PC and exported a QT .mov file using DNxHD codec with the 1080/59.94i 220 10-bit setting. My FCP editor also installed DNxHD on his Mac. He's able to view properties of the .mov in FCP: frame size = 1440x1080 fps
