Not that easy to spot which is 10bit and which is 8bit. Till you pull a key!. Quite suprised how much quality is lost in 2bits. We were pretty sure it was a 4:2:2 problem. Live n learn.
Thanks to Nick for the info on this issue.
-Quicktime decodes 8 bit 4:2:2 media to RGB without any smoothing applied to the U and V channels, but it does apply smoothing with 10 bit 4:2:2 media-
So could this be why Prores export in QT has a 4:4:4 smoothing option ?.. intresting...
