How do you merge Mask Layers together.

I would like to know if there is a way to merge mask Layers together, note image


It may not be needed but I would like to know if there is a way that is the question can it be done if so how? Please and Thanks.

A Mix node set to either Add or Subtract should do it.

What do you mean, “merge”? For what purpose? The default setting is “merge add”, which usually gives the best result to use for masking.

Unless you want to use one to cut a hole in the other, then its subtract.

EDIT: I use multiple layered masks in the VSE as it’s not so easy to stack them as strips.

Thanks though for what I have it probably would of been easier to just combine the two layers into one though I don’t know if that is possible. Thanks this should be helpful as I work on the more complex things I have.
