CS5 seems to get out of sync if I change the speed curve of a video on the timeline and then change the curve of brightness/luminance afterwards.
Any help would be very much appreciated.
I dont read German but are you sure that you are setting a luminance key frame?.
I think you are maybe affecting Opacity.
Opacity has a habit of leaving "opacity droppings" on the clip. ( ie. unwanted key fames)
