Nodes
Combine Masks
Add, subtract or intersect two mask sequences.
Takes Mask A and Mask B, both Mask Frames, and outputs one combined sequence. Both
inputs are required.
Operation
| Operation | Result |
|---|---|
| Add (A or B) | Masked where either input masks |
| Subtract (A minus B) | Everything in A that B does not cover |
| Intersect (A and B) | Only where both mask the same pixel |
Invert Result flips the finished mask, white becoming black.
Resolution
If the two inputs are different sizes, an Output Resolution choice appears so you can pick which one wins.
Different aspect ratios are a different matter. The node refuses those rather than delivering a stretched result, since there's no sensible way to reconcile them.
Typical Use
Masking several subjects with separate AI Mask nodes and merging them, or cutting one mask out of another.
To simply exclude or restrict a solve to one mask, you don't need this node. Auto Track has a Mask Mode that reads a single mask either way.
