Sample Specifies which values the effect samples from the source layer and subsequently applies to the effect layer.
• Average Averages all RGB values from all opaque pixels in the source layer. This is useful if you are selecting a
specific region of pixels defined with a mask. Median samples the pixel value that falls in the middle of all RGB
values.
• Brightest Samples the brightest RGB value, using lightness, and Darkest samples the darkest RGB value, also
using lightness.
• Max RGB Samples the highest value of the individual RGB channels. Min RGB samples the lowest value of the
individual RGB channels.
• Average Alpha Samples only the average alpha channel value. Median Alpha samples the value that falls in the
middle of all alpha channel values. Max Alpha samples the highest value of the alpha channel. Min Alpha samples
the lowest value of the alpha channel.

Opacity Specifies the transparency of the effect layer.
Blending Mode Specifies the blending mode that the effect uses to combine the new colorized layer with the original
layer. Blending modes are not available when averaging alpha channel values in the layer.
Color Stabilizer effect (Pro only)
The Color Stabilizer effect samples the exposure of specified areas of a single reference, or pivot, frame; it then adjusts
the total exposure of all the other frames to maintain the value of the selected point in the pivot frame. This is useful
to remove flicker from footage and to equalize the exposure of footage with color shifts caused by varying lighting
situations.
This effect works with 8-bpc and 16-bpc color.
Adjust the following controls for Color Stabilizer:
Set Frame Specifies the pivot frame. Display the frame that has the area of brightness or color that you want to
match, and click Set Frame.
Stabilize Specifies the method by which the stabilization is performed. Choose one of the following options from
the menu:
• Brightness Specifies that the brightness is to be stabilized throughout the footage. You can sample one point in
the pivot frame to specify this value.
• Levels Specifies that black-point and white-point values in the pivot frame are to be stabilized throughout the
footage.
• Curves Specifies that black-point, white-point, and midpoint values in the pivot frame are to be stabilized
throughout the footage.
