Matte Edge Mode box
  Select whether to use the Basic, Advanced or Smooth edge-detection algorithm. Certain settings change based on this selection.

### Basic Settings

Width field

Minimum Input field
  Displays the lower limit of the luminance values. Pixels with lower values are mapped to black. Editable.

Maximum Input field
  Displays the upper limit of the luminance values. Pixels with higher values are mapped to white. Editable.

### Advanced Settings

Minimum Input field
  Displays the lower limit of the luminance values. Pixels with lower values are mapped to black. Editable.

Maximum Input field
  Displays the upper limit of the luminance values. Pixels with higher values are mapped to white. Editable.

Inner Width field
  Displays the width of the inner edges of the matte. Editable.

Outer Width field
  Displays the width of the outer edges of the matte. Editable.

Width Proportional button
  Enable to affect the inner and outer width proportionally.

Inner Softness field
  Displays the level of softness on the inner edges of the matte. Editable.

Outer Softness field
  Displays the level of softness on the outer edges of the matte. Editable.

Softness Proportional button
  Enable to affect the inner and outer softness proportionally.

### Smooth Settings

Smooth Minimum field
  Enter a lower limit for the edge detection. Editable.

Smooth Maximum field
  Enter the upper limit for the edge detection. Editable.

Smooth Softness field
  Enter a value for softness of the edge. Editable.

Smooth Gain field
  Enter a value for the softness gain of the edge. Editable.

## Shrink Settings

Shrink button
  Enable to remove pixels from the edge of the matte.

Shrink Mode box
  Select whether to use shrink in a single pass or iterative mode. Single Pass mode allows you to control edge softness.

Shrink Width field
  Displays the width of the border that is removed from the edge of the matte. Editable.

Softness field
  Displays the amount of softness applied to the edges of the matte.

Minimum Input field
  Displays the lower limit of the luminance values. Pixels with lower values are mapped to black. Editable.

Maximum Input field
  Displays the upper limit of the luminance values. Pixels with higher values are mapped to white. Editable.

## Erode Settings

Erode button
  Enable to blend the light and dark edges of the matte.

Erode Width field
  Displays the width of the matte border to soften. Editable.

## Blur Settings

Blur button
  Enable to apply a softening Gaussian blur filter to the edge of the matte.

Blur Width field
  Displays the width of the blur applied to the edge of the matte. Editable.

Blur Height field
  Displays the height of the blur applied to the edge of the matte. Editable.

Proportional button
  Enable to constrain blur amount proportions.

## Matte Luminance Curve Settings

Matte Luminance Curve
  Controls the blending of the edges.You can add keyframes to the curve using Add mode, move keyframes with Move mode, and modify the curve's shape using tangent handles.

Reset box
  Resets the curve view.

Home button
  Reverts to the original view.

## Noise Settings

Noise button
  Enable to add noise to the transparent areas of the matte.

Noise Mode box
  Select the mode of noise to apply throughout the length of the image. Static adds noise as a still frame; Impulse adds noise that changes at each frame.

Select: | To add noise:
--- | ---
Static | As a still frame. You can move the static noise using the Position X and Y fields.
Impulse | Changing at each frame, but always starting from the same seed.

Weight field
  Displays the level of noise in the clip. Values below 1 add more white noise, and values above 1 add black noise. Editable.

Softness field
  Displays the level of Gaussian softness added to the noise. Editable.

Position X field
  Displays the X position of the noise when using Static mode. Editable.

Position Y field
  Displays the Y position of the noise when using Static mode. Editable.

Size X field
  Displays the size of the noise along the X axis. Editable.

Size Y field
  Displays the size of the noise along the Y axis. Editable.

Proportional button
  Enable to affect the X and Y sizes proportionally.
