Interesting, I do not get a smoother transition when using the Solid Composite effect. If I do the same transition (from black to 30% gray over 10 seconds) using both methods, I get the same result, i.e. major stepping as it moves through certain places in the gradient.
Also, 16bit of color depth per channel should be WAY more than enough to prevent this type of posterization / stepping. Im wondering if it is simply my 8-bit display?
Thanks for the feedback Kevin!
