I noticed this bug when moving DCP J2K encoding to CS6. AE is creating posterized color bands under certain conditions from a client supplied ProRes 4444 file.

CS5.5 however works just fine. In a 90 minute documentary it only occurred on highlights during dissolves and fades where some banding in color channels was 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. But going from 16 to 8-bit did.
Appears to me to be a bug – anyone else seen this type of thing?

A film is – or should be – more like music than like fiction. It should be a progression of moods and feelings. The theme, what’s behind the emotion, the meaning, all that comes later.
