The video looks pretty clean, then when I export from either FCPX or Motion it looks as bad as the original. The source clips are from a Panasonic GH2 directly imported into FCPX. So AVCHD rewraped to QT files.
Running FCPX 10.1.1, Motion 5.1, and Neat Video plugin 3.5.
I figured out it was Quicktime player. It looks fine in other players like VLC and importing it back into Motion/FCPX. I figured this out after i had a banding issue on a 3D render.
