timeā€”on this layer. I'll then take the Mode value for this mask
to None in the Timeline panel so that it doesn't affect the layer
directly. To restore more of the subject (i.e., foreground), open the
Cleanup Foreground area and select Mask 3 from the Path drop
down in the Cleanup 1 area. (Fig. 10.20)
Because we chose this mask in the Cleanup Foreground area,
it will cleanup, or restore, pixels. Again, this comes in the form of
a stroke around the mask. You can control the size of the stroke
with the Brush Radius value, or the hardness of the stroke with
the Brush Pressure value (Fig. 10.21).
If we wanted to remove more of the pixels in this matte, we
would go into the Cleanup Background area, and go through the
same process there. Fig. 10.22 shows the same mask as seen in
Fig. 10.21, but used to cleanup the background. The masks have
been deactivated in this screenshot so that the removed pixels
will be more obvious.
Using Open Masks
If there's one tiny
little spot that's
bothering you, an
entire closed path that has
a stroke around all edges
might be overkill. You can
also use open paths for
cleaning up our matte in
the Inner/Outer Key effect,
which are great for those
tiny problems.
Figure 10.20 Choose the
mask that you created (Mask 3,
in my case) from Cleanup
Foreground>Cleanup 1>Path.
