Revolution and ColorSync?

Hi Josh,

Apparently, QT Player takes some gamma value into account, while the  
Rev player object can't do that. I don't think there is any solution  
for this other than using a different codec (which won't take any  
gamma values into account at all).

In Revolution, one may set a gamma value, but it applies to PNG images  
only, AFAIK.

Are you sure that your player object doesn't have any inks or  
blendLevel set?

Best regards,

Mark Schonewille
