Motion Blur

Overview

 

Blurs an image by streaking it over the perimeter of a shape.  Results are similar to photographing a rapidly moving subject, or photographing a stationary subject with a moving camera.

 

 

Motion-Blur

Inserting an inverted radial gradient in the Blur Radius input

and activating the Face Center property will result in a zoom blur.

 

 

 

Inputs

 

 

Input

Description

Original

The original image that is to be blurred.

Blur Radius

This node blurs an image by streaking it over the perimeter of a shape.  The Blur Radius input modifies the size of that shape at each point, with brighter shades of red resulting in a larger shape being used at that location.

Angle

The Angle input rotates the shape used to streak its input at each point.

 

 

 

Properties

 

 

Property

Description

Shape

Specifies the shape used to streak the original image.  For example, if Circle is selected, the image will be streaked along circular paths.

Radius

Controls the size of the shape used to streak the original image.  The value of this property is multiplied into the Blur Radius input, if one is supplied.

Angle

Rotates the shape used to streak the original image.  This value is added to the Angle input, if any is provided.

Samples

Controls the quality of the blur operation.  Higher values will result in smoother output, but will take longer to render.

Face Center

Rotates the shape used the streak the image in such a way that it always faces the center of the image.  This option is useful for creating zoom blurs, as shown in the illustration above.

Seamless

Controls whether the resulting blur will be seamlessly repeatable.
