Smoothing Specifies the amount of anti-aliasing (softening) applied to the boundary between transparent and opaque
regions. Choose None to produce sharp edges, with no anti-aliasing. This option is useful when you want to preserve
sharp lines, such as those in titles. Choose Low or High to produce different amounts of smoothing.
Mask Only Displays only the clip’s alpha channel. Black represents transparent areas, white represents opaque areas,
and gray represents partially transparent areas.
Drop Shadow Adds a 50% gray, 50% opaque shadow offset 4 pixels down and to the right from the opaque areas of the
original clip image. This option works best with simple graphics such as titles.
Track Matte Key
The Track Matte Key reveals one clip (background clip) through another (superimposed clip), using a third file as a
matte that creates transparent areas in the superimposed clip. This effect requires two clips and a matte, each placed
on its own track. White areas in the matte are opaque in the superimposed clip, preventing underlying clips from
showing through. Black areas in the matte are transparent, and gray areas are partially transparent.
You can create mattes in various ways:
• Use the Titles view to create text or shapes (use only grayscale images if you plan to key using luma information),
save the title, and then import the file as your matte.
• Create a matte from any clip by using the Videomerge effect, Chroma Key, Blue Screen Key, Green Screen Key, or
Non Red Key keying effect; then choose the effect’s Mask Only option.
• Use Adobe Photoshop Elements, Adobe Illustrator, or Adobe Photoshop to create a grayscale image and import it
into Adobe Premiere Elements.
The Track Matte Key has the following controls:
Matte Lists the video tracks that contain clips that could be used as mattes. Choose one from the list.
Composite Using Selecting Matte Alpha from this pop-up menu sets the matte’s transparency based on its alpha
channel. Matte Luma sets transparency based on the matte’s luminance or brightness.
Reverse Reverses the order of the background and foreground clips.

Airbrush
The Airbrush effect creates an airbrushed effect by smoothing colors while maintaining sharp edges.
Spray Lets you set the width of the airbrush nozzle. Increase the spray value to make the colors blend together over
larger areas. Decrease the spray value to make individual color details become more evident.

Colorize
The Colorize effect turns the image black-and-white, and then enhances specific areas using one or two colors that you
specify. The areas that are enhanced are those that contain one of the two colors you specify. You can specify the two
paint colors that dominate the image, and adjust how much color is applied.
