The Video Preview in Sequence settings was set to YUV 10 uncompressed.
With ProRes 10 bit , it was no difference.
Real time monitoring is still full of banding.
My problem isn’t the render. I need a full quality blackmagic 10 bit playback on my Dreamcolor during edit.
You can easily test this. Create a animated Gradient or a blurred circel in a 10 Bit FCP sequence. Export.
Import the file in Premiere. And try to get a proper 10 bit image on a 10 Bit Monitor.
That same quicktime works perfect when importing back in FCP7 and playback Blackmagic 10 bit.
The gradient is ultra smooth.
Not in Premiere.
