S_Median

Applies a median filter to the source image. Median filters are useful for cleaning up isolated spots and noise.

In the Sapphire Blur+Sharpen effects submenu.

Inputs:

• Source: The current layer. The clip to be filtered.

• Mask: Defaults to None. Interpolate between the result and the Source input. White areas use the result of the effect. Black areas use the Source clip.

Parameters:

• Load Preset (Push-button) Brings up the Preset Browser to browse all available presets for this effect.

• Save Preset (Push-button) Brings up the Preset Save dialog to save a preset for this effect.

• Mode (Popup menu, Default: Median) Selects whether to apply the same median filter to all channels, or a separate median filter per channel.

  • Median: Apply the same median filter to each channel.
  • MedianChannels: Apply different median channels to the r, g, and b channels.

• Mocha Project (Default: 0, Range: 0 or greater) Brings up the Mocha window for tracking footage and generating masks.

• Blur Mocha (Default: 0, Range: 0 or greater) Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

• Mocha Opacity (Default: 1, Range: 0 to 1) Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

• Invert Mocha (Check-box, Default: off) If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

• Resize Mocha (Default: 1, Range: 0 to 2) Scales the Mocha Mask. 1.0 is the original size.

• Resize Rel X (Default: 1, Range: 0 to 2) The relative horizontal size of the Mocha Mask.

• Resize Rel Y (Default: 1, Range: 0 to 2) The relative vertical size of the Mocha Mask.

• Shift Mocha (X & Y, Default: [0 0], Range: any) Offsets the position of the Mocha Mask.

• Dilate Mocha (Default: 0, Range: -100 to 100) Dilates or erodes the Mocha Mask by this pixel amount before using.

• Dilation Quality (Popup menu, Default: Fast) Selects whether Dilate Mocha adusts quickly in default Fast mode or looks better in High quality mode.

  • Fast: Dilate Mocha in Fast mode for quick adjustments.
  • High: Dilate Mocha in High quality mode for a better looking mask shape.

• Bypass Mocha (Check-box, Default: off) Ignore the Mocha Mask and apply the effect to the entire source clip.

• Show Mocha Only (Check-box, Default: off) Bypass the effect and show the Mocha Mask itself.

• Combine Masks (Popup menu, Default: Union) Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.

  • Union: Uses the area covered by both masks together.
  • Intersect: Uses the area that overlaps between the two masks.
  • Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

• Size (Default: 1, Range: 0.1 to 40) Size of the median filter.

• Subpixel (Check-box, Default: off) Enables subpixel-width filtering. Use this for smoother animation of the Size parameter.

• Size Rel X (Default: 1, Range: 0.1 to 5) The relative horizontal size of the filter.

• Size Rel Y (Default: 1, Range: 0.1 to 5) The relative vertical size of the filter.

• Red Rel Size X (Default: 1, Range: 0 to 2) The relative horizontal size of the filter in the red channel.

• Red Rel Size Y (Default: 1, Range: 0 to 2) The relative vertical size of the filter in the red channel.

• Green Rel Size X (Default: 1, Range: 0 to 2) The relative horizontal size of the filter in the green channel.

• Green Rel Size Y (Default: 1, Range: 0 to 2) The relative vertical size of the filter in the green channel.

• Blue Rel Size X (Default: 1, Range: 0 to 2) The relative horizontal size of the filter in the blue channel.

• Blue Rel Size Y (Default: 1, Range: 0 to 2) The relative vertical size of the filter in the blue channel.

• Alpha Rel Size X (Default: 1, Range: 0 to 2) The relative horizontal size of the filter in the alpha channel.

• Alpha Rel Size Y (Default: 1, Range: 0 to 2) The relative vertical size of the filter in the alpha channel.

• Mask Use (Popup menu, Default: Luma) Determines how the Mask input channels are used to make a monochrome mask.

  • Luma: the luminance of the RGB channels is used.
  • Alpha: only the Alpha channel is used.

• Blur Mask (Default: 0.05, Range: 0 or greater) Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

• Invert Mask (Check-box, Default: off) If on, inverts the Matte input so the effect is applied to areas where the Matte is black instead of white. This has no effect unless the Matte input is provided.
