Kevin, Thanks for the fast reply!
I updated my cuda driver… And it did nothing…
I changed my render setting to the mercury playback engine to the software only… did nothing to help…
Then I pulled a video layer out of the mix and the fade up worked. When I have more then one adjustment layer in the stack, no matter the stack order the opacity doesn’t apply at varying levels. Only 0% or 100%. My guess would be a bug.
