Creating a mask blur effect
$ Shape Transparency Sets the transparency of the shape and the area
around the shape. At the default setting (0), the shape is completely opaque
and the area around the shape is transparent. Dragging the slider to the left
increases the transparency of the shape, which makes the blur less apparent.
Dragging the slider to the right decreases the transparency of the area
around the shape, which increases the amount of blurring outside the mask
area.
$ Outside Transparency Sets the transparency level of the area outside
your mask.
¦NoteThe Outside Transparency setting is applicable only if you’ve
scaled down, moved, or rotated your mask using the transform controls so that
the mask doesn’t cover the entire screen.
$ Softness Lets you apply blurring to the edges of your mask.
$ Invert Mask Select this option if you want to invert the opaque and
transparent areas of your mask.
$ Apply Crop to Video Only Select this if you want the mask to be
squeezed to fit your cropped clip. If you don’t select this option, the mask
will be cropped by the same amount that you crop your clip.
$ Transform Use these controls to apply or change various transform
settings for your mask blur effect, such as the position, scale, and rotation
of the mask. For more information, see “Transforming your clip” on
page 52.

depending on your project’s video format.
