I have a 1 1/2 minute project with video and transitions and effects. When I create my movie there are certain frames that are pixilated on the generated video. I have no issues when I run the preview in FCPX. I have tried the computer mode all the other apple options but nothing seems to stop it. I even tried generating one that produced a file 16GB big and still it did not work. Does anyone have any suggestions as I have googled and cannot seem to find an answer.
