Composites using the track matte clip's luminance values.
Matte Luma
10 (Optional) Select the Reverse option to invert the values of the track matte clip.
To retain the original colors in the superimposed clip, use a grayscale image for the matte. Any color in the matte
removes the same level of color from the superimposed clip.
11 (Optional) If you're animating the Track Matte, move the current-time indicator either in the Effect Controls panel
or Timeline panel and change the Track Matte Key settings.
A new keyframe appears in the Effect Controls timeline when you change the settings. You can also adjust the
interpolation between keyframes by editing the keyframe graph. Repeat this step as needed.

Noise & Grain effects
Dust & Scratches effect
The Dust & Scratches effect reduces noise and defects by changing dissimilar pixels within a specified radius to be more
like their neighboring pixels. To achieve a balance between sharpness of the image and hiding defects, try various
combinations of radius and threshold settings.

How far the effect searches for differences among pixels. High values make the image blurry. Use the smallest
Radius
value that eliminates the defects.
How different pixels can be from their neighbors without being changed by the effect. Use the highest value
Threshold
that eliminates the defects.
Median effect
The Median effect replaces each pixel with a pixel that has the median color value of neighboring pixels with the
specified Radius. At low Radius values, this effect is useful for reducing some types of noise. At higher Radius values,
this effect gives an image a painterly appearance.
