Alpha greenscreen footage with two video clips
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 appreciated.

Key the Greenscreen.
Use set mattes and invert.
Or in the latest version of after effects, track mattes with alpha / alpha inverted of your layers can all point to the same green-keyed layer.
