Blur Type Settings
 Blur Type for Gaussian |
 Blur Type for Radial |
- Blur Type box
- Select the type or shape of blur filter to apply to the clip. Depending on the blur type, some of the other blur settings may vary.
- Bokeh Blur field
- Displays the amount of smoothness applied to sharp bokeh edges. This creates the blur that is applied to out-of-focus points of light to simulate a shallow focus. Editable.
- Bias field
- Displays the direction of a blur. Enter a positive value for forward, a negative value for backward, or 0 for a blur that moves in both directions. Available when Directional or Radial Stamp is chosen as the blur type.
- Radial Mode box
- Select whether a radial blur or glow moves in one circular direction (Spin) or two rotating directions (Twist). Available when Radial is chosen as the blur type.
- Samples field
- Displays the quality of a Radial Stamp blur or glow. Editable. Available when Radial Stamp is chosen as the blur type.
Color Space Settings
- Colour Space box
- Select whether to blur in RGB or YUV space. The Channels settings change to reflect this setting.
Centre Settings (Radial Only)
- Stabilizer button
- Opens the Stabilizer menu to track the centre of the blur from the source clip.
- Centre X field
- Displays the X position of the centre of the radial blur (or gesturally move the red circle in the image). Editable.
- Centre Y field
- Displays the Y position of the centre of the radial blur (or gesturally move the red circle in the image). Editable.
Note: You can also move the red circle on the image to set the position of the centre of the blur. The Centre X and Y fields update accordingly.
- Absolute/Relative box
- Select whether to position and offset the centre of the radial blur in a relative mode (expressed as a percentage) or absolute mode (expressed in pixels).
- Offset X field
- Offsets the centre along the X axis (or press Ctrl and gesturally move the red circle in the image).This field is useful to apply changes to the centre after tracking has been performed. Editable.
- Offset Y field
- Offsets the centre along the Y axis (or press Ctrl and gesturally move the red circle in the image). This field is useful to apply changes to the centre after tracking has been performed. Editable.
Note: You can also press Ctrland move the red circle on the image to set the offset of the centre blur.
Front Settings
- Width field
- Displays the width of the blur.Increasing the blur increases the render time. Editable.
- Height field
- Displays the height of the blur.Increasing the blur increases the render time. Editable.
- Proportional button
- Enable to affect the width and height proportionally.
- Pixel Ratio button
- Enable to blur the image using the same proportion as its aspect ratio.
- Gain field
- Displays a value by which pixel colour values are multiplied. The offset value is added to this value to determine the final colour. Editable.
- Offset field
- Displays the value to add to current pixel colour values. The resulting colour value is clipped at 0. Editable.
- Length field (Directional)
- Displays the radius amount of a directional blur. Editable.
- Angle field (Directional)
- Displays the angle of a directional blur. Editable.
- Amount field (Radial, Radial Stamp)
- Displays the amount of radial blur. Editable.
- Rotation field (Radial, Radial Stamp)
- Displays the angle of rotation for a radial blur. Editable.
Blooming Settings (Defocus Only)
- Basic/Additive Blooming button
- Switch between basic blooming and additive blooming bokeh effects. The basic blooming mode displays the gain applied to highlights in non-HDR images, to allow the creation of bokeh patterns without affecting colour integrity. The additive blooming mode allows you to create higher intensity bokeh patterns from any source image, using minimum and maximum thresholds for highlight segregation.
- Basic Blooming field
- Displays the gain applied to highlights in non-HDR images, to allow the creation of bokeh patterns without affecting colour integrity. This creates the glow effect that is applied to the bright spots of the image to simulate light bleeding, or blooming, over the edges. Editable.
- Additive Blooming field
- Displays the amount of high intensity bokeh patterns that can be created from any source image generating extreme highlight content . Editable.
- Additive Blooming minimum field
- Displays the minimum threshold for highlight segregation. Editable.
- Additive Blooming maximum field
- Displays the maximum threshold for highlight segregation. Editable.
Matte Settings
 Matte Settings for Gaussian, Defocus, or Box |
 Matte Settings for Radial or Radial Stamp |
 Matte Settings for Directional |
- Matte Width field
- Displays the width of the blur for the matte. Editable.
- Matte Height field
- Displays the height of the blur for the matte. Editable.
- Matte Length field
- Displays the radius amount of a directional blur for the matte. Editable.
- Matte Angle field
- Displays the angle of a direction blur of the matte. Editable.
- Matte Amount field
- Displays the amount of radial blur for the matte. Editable.
- Matte Rotation field
- Displays the angle of rotation for a radial blur for the matte. Editable.
- Lock To Front button
- Enable to keep the matte values the same as their corresponding values for the front clip.
- Invert Matte button
- Enable to blur the region outside the area defined by the matte.
Channel Settings
 RGB Channels |
 YUV Channels |
- Weight field
- Displays the weighted value of the channel.
- Position X field
- Displays the horizontal offset of the channel.
- Position Y field
- Displays the vertical offset of the channel.
- YUV Colour box
- Select whether to affect Luma or Chroma only, or include both when blurring in YUV colour space.
Blending Settings
- Screen option box
- Select a logical operation that can be used to blend the front clip and the result clip.
- Transparency field
- Displays the percentage of blending when the result is composited on the front clip. Editable.
- Use Matte button
- Enable to apply the blur with the areas defined by the matte.
Rendering Settings
- Rendering Mode box
- Select whether to render in Automatic, Progressive or Interlaced mode.
Kernel Settings (Defocus Only)
The kernel is the defocus blur shape. The shape of the kernel is determined by its number of sides, its rotation, and the shape of its S-curve. This curve represents the shape of the pattern, from its centre to the outside. The default S-curve defines the softness of the blur. You can change the curve by manipulating the two points that define the curve, or you can add points to the curve. Use the Tools box to add and delete points on the curve.
- Sides field
- Displays the number of sides in the kernel shape. Editable, if kernel information is not attached to the node.
- Rotation field
- Displays the angle of rotation of the kernel shape. Editable, if kernel information is not attached to the node.
- Bokeh Type box
- Select whether to use a round or angle bokeh curve to define the kernel shape.
- Curvature field
- Displays the amount of curvature applied to a round bokeh kernel shape. Editable.
