Thank you Bret! you entirely understood my post. Yes QT playback engine seems to be inferior to X at least for prores on flat colors but haven’t tried under OSX 10.11.x with 10bit core.

I changed the title of the post, initially I thought FCPX was exporting bad prores but now it appears QT doesn’t play it well, surely I must be wrong, if not, thats pretty bad for QT and other players, must be a system core thing, I don’t know.

The image on the bottom left is source file QT frame grab, Ive updated the image to make it clearer, see blue/green text

Thanks Noah.

Yes export from FCPX to prores is good, its just that solid colors don’t display well on quicktime/VLC from my findings.

As for H264 if you guys aren’t surprised at my findings, then I guess H264 or any lossy compressed formats is what it is & have to live with it.

Cheers folks.

Hey Oliver thanks for stopping by.

I was just (1) surprised to see a big difference in the way quicktime/VLC handles prores display Vs prores display when played within FCPX and (2) the hard hitting compression FCPX/H264 applies on flat colors, yes granted, thats the whole point about compression, it compressor similar colors & other similar portions of a frame depending on many factors but was just surprised at how nice a job it does in others areas within the frame of well lit even highly detailed footage Vs the highly compressed flat colors of the frame, if there was just a slider to minimise compressing flat colors too much that would be a nice compromise/balance.

To see the difference in my posted image view it at full screen size.

Ok so I am attaching an updated file with more findings
