Matte Filters
Matte filters can be used by themselves to mask out areas of a clip, or to create alpha
channel information for a clip to make a transparent border so that the clip can be
composited against other layers. Matte filters can also be used to make further adjustments
to layers with key filters applied to them. For detailed information, see Using Mattes to
Add or Modify Alpha Channels.
ResultFilter
Generates an eight-point polygon you can use to crop out portions
of a clip. Eight-point controls allow you to define the polygonal
matte. The Smooth slider rounds off the corners of the polygon to
create rounder mattes. The Choke slider allows you to expand or
contract the matte, and the Feather slider allows you to blur the
edges of the matte. The Invert checkbox reverses what’s matted
and what’s transparent, and the Hide Labels checkbox hides the
number labels, which indicate which point of the matte corresponds
to which point control of the filter.
Eight-Point Garbage Matte
Produces a matte around the clip, similar to a luma key. A View
pop-up menu allows you to look at the source of the clip (with no
key applied), the matte created by the filter, the final matted image,
or a special composite of the source, matte, and final image for
reference. Use the Threshold, Tolerance, and Soft sliders to adjust
the matte. The Copy Result pop-up menu allows you to copy the
luma result to the RGB or alpha channel of your clip, and the Invert
checkbox allows you to invert the result.
Extract
Works similarly to the Eight-Point Garbage Matte filter but creates
a four-point polygonal matte.
Four-Point Garbage Matte
Takes the alpha channel or luma from another clip and uses it to
create a matte for the current clip. The Mask clip well allows you to
select the clip from which to take the alpha channel or luma values.
The Channel pop-up menu lets you choose whether to use the clip’s
alpha channel or luma level. The Invert checkbox allows you to
invert the resulting matte. This filter is especially useful for taking
custom edge masks that you can create with any image editor and
applying them to clips in your sequence that you want to matte
the edges out of. Unlike the Travel Matte composite mode, the
Image Mask filter attaches a matte to the selected clip. You can use
motion effects to move the affected clip around, and the matte
follows.
Image Mask
Blurs the alpha channel of the clip by the amount you specify with
the Soft slider.
Mask Feather
Generates a mask shape to use to matte out the clip. You can choose
a diamond, oval, rectangle, or round rectangle from the Shape
pop-up menu. Use the Horizontal Scale and Vertical Scale sliders to
adjust the size and aspect ratio of your mask shape. The Center
point control allows you to specify the center of the mask, and an
Invert checkbox lets you reverse what’s transparent and what’s solid.
