A blur brush to use when cleaning up mattes
I have generated a key of an eagle flying, using roto brush and refine edge brush. The alpha channel is then rendered, and brought in as a monochrome clip, and this key clip then needs to be cleaned up frame by frame using the brush tool.
To help create a better key, a blur brush that softens the edge of the key as you paint on it, would be super useful, where you can set the level of blur applied as you paint.
