Hi Björn, my findings according to avoid banding while converting from 10bit to 8bit codecs are: - mixdown in DNxHD 185X (with 10bit timelineview enabeled) an then export to for example MXF OP1a XDCAM 422 (which is 8Bit) - render all your effects or a dummy-effect with media creation settings: DNxHD 185X, 16bit effects prpcessing and then export
