User Manual

Since windows can be individually tracked and keyframed, you can quickly set up complex
interactions of windows to solve common problems you’ll encounter. For example, when you’re
tracking a window to follow a moving subject that moves behind something in the frame, you
can use a second window with Mask turned off to cover the object in front. Now, when the
tracked window intersects the subtractive window, the correction will disappear along with
the subject.
You can also use the Mask control to create more complex shapes than you can with a
single window.

Furthermore, once you reach the limits of what shapes you can create using the four available
windows, you can combine multiple nodes containing multiple shapes and qualifiers using the
Key Mixer.
