[Robin S. Kurz] “Pretty much an “Eat your cake and have it, too” situation, no? And I suspect that you just don’t notice it in the QT Player due to the display size. Because the QT Player (X) most certainly doesn’t deinterlace on the fly. QT 7 had an option for that.”
I’m running QT 10.5 full screen and it looks just fine, which is not the case when I run FCP X full screen (same screen size)
