Chapter 10 Using Filters 765
Matte Filters
Matte filters are used to modify mattes.
Matte Choker
This filter increases or decreases the semi-transparent area of an object’s alpha channel
by performing a gamma correction (similar to the Gamma color correction filter) to all
regions of the alpha channel falling between solid black and solid white. This allows
you to widen or narrow the semi-transparent areas within an object, while leaving all
100 percent solid and transparent areas unaffected.
Parameters in the Inspector
Edge Thin: Higher positive edge thin values eat into the alpha channel, eliminating
fringing around the edges of translucent areas. Negative values fill in translucent areas,
filling in holes and widening the matte into regions of fringing.
Feather: Lower values reduce the amount of translucency in a matte, but this results in
harder edges around holes and edges in the alpha channel.
Dashboard controls
The Dashboard contains the Edge Thin and Feather controls.
Set Matte (Obsolete)
This filter lets you apply the alpha channel from one object to another. You can also
deploy this filter to use any color or luminance channel from an image as an alpha
channel.
Important: This filter is no longer available in Motion. It is present in Motion 1.0
projects that already have it applied. Use Image Mask to duplicate its functionality. See
“
Applying Image Masks to an Object” on page 865.
Parameters in the Inspector
Matte Source: Lets you set the object to use as a matte.
Matte Channel: Lets you choose which channel of the matte source image to use as a
matte. The choices are Red, Green, Blue, Alpha, Luminance, On, and Off.
Invert Matte: Turning this checkbox on inverts the matte effect that is created.
Stretch Matte: Turning this checkbox on stretches the source image to the same size
as the object being matted.
Composite Matte: Toggles whether or not the matte being attached adds to the
existing matte, or replaces it.
Dashboard controls
The Dashboard contains the same controls as the Inspector.
