Using cc composite with keying not working properly

Hi,

I’m trying to make my keying workflow faster by using cc composite but it doesn’t work good.

Usually what I’m doing:

1. Create a layer with – keylight + advanced spill suprresor.
2. Create “core-matte” to fill holes. The steps are:
   1. Duplicate the first layer, put the new one underneath.
   2. lower the clip white value + screen shrink.

When I’m trying to do the same by using cc composite on one layer only, I still got the holes.

What do I miss?

*I unchecked RGB only. *Photos attached.

Thanks,

Elad
