After creating RotoBrush settings, does Refine Edge settings supersede?

[Letty2019]

Hello,

If I use RotoBrush, and then create some custom settings, say, 12% feather...

Then I go back and use the Refine Edge Tool and in that tool's settings add another 10% feather.

If my feather now at 22% ?  Or does the Refine Edge delete the prior settings and my feather is only 10% ?

Thank you!

The feather is never 22%, anyway. That's not how the math works. Otherwise the effects don't really know much about each other or else Refine Edge wouldn't work on keying as well if it were dependent on RB data.

I confused the feather with the contrast.

OK, so if feather is set at 12  (btw, is that 12 pixels or 12 what?)  so if feather is 12 in rotobrush,  then when Fine Edge does it's thing and I add 10 to the Edge feather,  your saying it's not adding to the original feather, it's starting from scratch and the new feather is 10?

I thought is was compounding the rotobrush feather + fine edge feather because doesn't Edge Fine tool use the RB data to determine where the Edge tool clings to?  If that RB edge is feathery, then the Edge tool will add to that feather? 

LOL  sorry, set me straight.

Thanks,

Letty
