I have shot a lot of footage with a P3P and when I upgraded to a new 5K IMac the quality of the footage is terrible now when viewed at full resolution. Has any one ideas why this has happend as when I edited it on my Mac Book air it looked ok. But now at full 4K it really looks bad... Just as a thought... Could it be that Final Cut Pro as not rendered it yet? Will try that now and see if that helps.. Yes it does... I had to render the clip first... Wow looks amazing!
