I am not sure if this is intended behavior or not..
Interesting find with Clip layers on color in Resolve 19.. Regarding Alpha channel ..
Say you have 4 layers enabled.
If you pull a key on layer 1 and output the alpha … it does not automatically patch through layers 2-4.
You need to add a source to layers 2-4, and also an alpha out .. and then patch through each layer to end using a corrector node in the middle..
I made a branch and used a single node to bypass nodes on layer 2… did the same for Layers 3-4.
Pic 1 we can see Santa here with a 3d keyer applied, and the alpha has been patched. However the Green background is not removed, and Grey Ramp background does not show up:
- Layer 2 pass alpha through:

Patching the Alpha through the additional layers using a Source and Alpha output on layers 2-4 will allow the alpha channel to work correctly:
- Layer 2 Pass through:

And so on for layers 3-4:
