Hi all,

I have 3 layers

1st layer is green screen footage

2nd layer, I would like to be alpha of the 1st layer

3rd layer, I would like to be inverted alpha of the 1st layer.

Basically have the green screen footage reveal one of the other layers under it.

I feel this is simple but I cannot for the life of me work out what to do.

Any help would be much…
