Blur Filters

Blur filters take many forms in Motion. They can be used to simulate the real-world blurring that occurs due to the depth of field in photographed material. They can also be used to create designed effects.

Channel Blur

Gives you control over blurring each color channel of an object. The Channel blur can be applied selectively to each color channel of an object: red, green, blue, and alpha.

Blurring individual channels allows you to create customized glow effects by retaining sharpness in selected channels while softening others.

Figure. Canvas showing effect of the Channel Blur filter.
Parameters in the Inspector
  • Amount: Sets the radius of the object blur.
  • Blur Red: Sets the blur to affect the red channel.
  • Blur Green: Sets the blur to affect the green channel.
  • Blur Blue: Sets the blur to affect the blue channel.
  • Blur Alpha: Sets the blur to affect the alpha channel.
  • Horizontal: Sets the percentage of maximum horizontal blur. This is a percentage of the Amount parameter.
  • Vertical: Sets the percentage of maximum vertical blur.
  • Crop: Sets whether the image is cropped beyond its original borders.
  • Mix: Sets the percentage of the original image to be blended with the blurred image.
HUD Controls

The HUD contains the following controls: Amount, Blur Red, Blur Green, Blur Blue, and Blur Alpha.

Circle Blur

Creates a circular blur within an image, specified by a center point that sets the center of the blur effect and a radius that sets the size of the affected region. The amount of blur in the affected area can also be customized.

This filter is useful for blurring a limited area in an image. For more sophisticated control of the image region to be blurred, use the Compound Blur filter.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Parameters in the Inspector
  • Center: Sets the position of the center of the blur effect. Drag the Center onscreen control to adjust its value in the Canvas.
  • Amount: Sets the amount of the blur.
  • Radius: Sets the radius of the circle defining the blurred area. Drag the outer circle of the onscreen controls to adjust the Radius value in the Canvas.
  • Crop: Sets whether the image is cropped beyond its original borders.
  • Mix: Sets the percentage at which the original image is blended with the blurred image.
  • Publish OSC: Publishes the filter’s onscreen controls in Final Cut Pro X. For more information on creating content for use in Final Cut Pro, see Creating Templates for Final Cut Pro X.
HUD Controls

The HUD contains the following controls: Amount, Radius, and Crop.

Compound Blur

Blurs an object using the specified channel of a designated map image. You can use any shape, text object, still image, or movie file as the map image. You can select any red, green, blue, alpha, or luminance channel to create the shape of the blur.

Tip: Use this filter to blur specific sections of an image. For example: trace the subject of the image to blur with a Bezier or B-spline shape, then assign this shape as the Blur Map image. Use its Luminance or Alpha channel to define the blurred area, then turn off the original shape object in the Layers list or Timeline to hide the source of the blur. For more information, see Editing Shapes.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.

Figure. Canvas showing effect of the Compound Blur filter.
Parameters in the Inspector
  • Amount: Sets the radius of the blur.
  • Blur Map: Displays a thumbnail of the current map. To add an object (image, shape, text, and so on) to use as the blur map, drag the object to the Blur Map well.

    Note: You can also apply or replace the blur map by dragging the source object onto the filter in the Layers list.

  • Invert Map: Sets whether the blur map is inverted.
  • Stretch Map: Stretches (or compresses) the map image so it exactly overlaps the image the filter is applied to.
  • Horizontal: Sets the percentage of maximum horizontal blur.
  • Vertical: Sets the percentage of maximum vertical blur.
  • Mix: Sets the percentage of the original image to be blended with the blurred image.
HUD Controls

The HUD contains the following controls: Amount, Blur Map, and Map Channel.

Defocus

Mimics the out-of-focus effect that occurs through a real-world camera lens. The Defocus filter blurs an image while creating realistic lens artifacts that mimic the aperture shape in brighter areas of the image. The shape of the blur can be customized.

Tip: Use this filter when you are trying to blur an image to match video or stills shot with a camera. For example, if you key a woman standing in front of a blue screen, and you intend to place a background image behind her to make it look like she’s standing in a valley with mountains in the background, use the Defocus filter instead of a Gaussian Blur to create a realistic depth-of-field effect for the mountains in the distance.

Figure. Canvas showing effect of the Defocus filter.
Parameters in the Inspector
  • Amount: Sets the radius of the defocus.
  • Gain: Sets the amount of gain applied to the high luminance areas.
  • Sides: Sets the number of sides of the lens aperture, if Shape pop-up menu is set to Polygon.
  • Rotation: Sets the angle of rotation of the polygonal lens aperture, if Shape is set to Polygon.
  • Aspect Ratio: Sets the aspect ratio of the lens aperture.
  • Crop: Sets whether the blur is cropped at the object’s original border.
  • Mix: Sets the percentage of the original image to be blended with the blurred image.
HUD Controls

The HUD contains the following controls: Amount, Gain, Shape, Sides, Rotation, and Aspect Ratio.

Directional Blur

Blurs an object along a specific angle. This filter creates a blurred streaking effect.

Note: The more filters you use in a project, the more you impact the performance of Motion.

Figure. Canvas showing effect of the Directional Blur filter.
Parameters in the Inspector
  • Amount: Sets the radius of the blur. Drag the arrow onscreen control to adjust the amount (and angle) of the blur in the Canvas.
  • Angle: Sets the angle of the direction of movement. Drag the arrow onscreen control to adjust the angle (and amount) of the blur in the Canvas.

Gaussian Blur

Creates a soft blur effect. The Gaussian blur is the softest blur effect you can apply and is a frequently used blur effect. By default, this filter affects the image uniformly, although you can control the amount of horizontal and vertical blur independently.

Gaussian blur is relevant for most motion graphics tasks, and can be animated for various focus-control effects. However, to more accurately simulate camera focus, the Defocus filter might be a better choice. For more information on the Defocus filter, see Defocus.

Figure. Canvas showing effect of the Gaussian Blur filter.
Parameters in the Inspector
  • Amount: Sets the radius of the blur.
  • Horizontal: Sets the percentage of the Amount applied in the horizontal direction.
  • Vertical: Sets the percentage of the Amount applied in the vertical direction.
  • Crop: Sets whether the object is cropped at its original boundaries.
  • Mix: Sets the percentage of the original image to be blended with the blurred image.
HUD Controls

The HUD contains the following controls: Amount, Horizontal, and Vertical.

Gradient Blur

Creates a graduated blur between two points. Point one is the beginning of the blur, and the point at which the image is at its sharpest. Point two is the end of the blur, and the point at which the image is at its blurriest, depending on the value set in the Amount parameter.

This filter causes rasterization in 3D groups. For more information on rasterization, see About Rasterization.
