You guys know that if you're using the Pen tool to mask out the area and you also can choose as Subtract...
How can we do it in RotoBrush Tool???
I know there're a button "invert foreground/background"
But that's not what i want
i'm shooting a video using F22
and i want the background to be very blur like shallow depth of field
and usually i'm using the Pen tool to mask out the area i don't want and subtract it
and apply the effects on it...
If i'm using RotoBrush Tool
Can i still do the same thing as the Pen tool....???
The only thing i want to know is
"How to Subtract the mask area using RotoBrush tool and apply the effects on the Subtract area..."
*Very Appreciate to those who commented and answer my questions
Wrong thinking. You don't work this way. You simply pre-compose the result of the Rotobrush and use it as a matte in another comp.
Any tutorial for what're you saying/talking???
Search for the term, "track matte".
