I have some footage in Pro res 4444 1920x1080p coming into AE ( and Premiere ) the footage is half res 960x540 in the Project window for some reason.
Played Directly in QT or FCPX it plays fine and full res.
I have ProRes 4444 as an export Codec in AE.
I have FCP7 too.
Anyone got any ideas
Try opening the file in QT Pro, view at full size, then save the file. That should fix it. I've seen this before.
