I noticed this bug when moving DCP J2K encoding to CS6. AE is creat= ing posterized color bands under certain conditions from a client supplied P= roRes 4444 file.

CS5= .5 however works just fine. In a 90 minute documentary it only occurred on h= ighlights during dissolves and fades where some banding in color channels wa= s present.

 

It does not occur if you set AE to 8-bit. Turning on/off MP,= disk cache, color management, different output modules etc. had no effect. B= ut going from 16 to 8-bit did.

&nb= sp;

Appears to me to be a bug =E2=80=93 anyo= ne else seen this type of thing?
