• Matte only: Shows the actual matte being used to limit the effect. This is similar to
the image displayed in the HSL Qualifier preview display, except that it shows the
sum of the vignette mask and the HSL mask, as well as the results of the mask as it’s
modified by the Key Blur parameter.

• Vignette outline button: When the Vignette button is turned on, the Vignette outline
button lets you display or hide the vignette outline that appears in the Preview window.
Isolating a Region Using the Vignette Controls
The vignette controls give you an extremely fast way to isolate areas of an image that
are geometrically round or rectangular, such as the face of someone in close-up, or a
window in the background. Vignettes are also useful for isolating subjects that are too
hard to key using the HSL qualifiers.
On the other hand, if the subject you’re vignetting moves, you need to either keyframe
the shape to move along with it (see
Keyframing ) or use motion tracking to automatically
create a path for the shape to follow. (For more information, see The Tracking Tab .)
