Alpha problem


#1

I am trying to fill alpha with white but unable to do so. I did keying with keyer. Got confused in roto node. Please Help


#2

If you want to completely fill the alpha, you can use a shuffle and set the alpha checkbox to white


#3

on roto node you can choose to paint on alpha (output) and after apply a premultiply node.
