Streak Blur Copernicus node

Streaks an image, adding a motion blur effect.

On this page

Parameters
Inputs
Outputs

Streak blurs an image in a single direction, creating an effect similar to motion blur. The direction and length of the streaks are constant.

Parameters ¶

Mask

The amount of the new value to mix in with the original value. Higher values mix in more of the new value. Lower values mix in less of the new value. A value of 1 means this node uses only the new value.

The default value is 1. See Mask for more information.

Direction Type

Whether the streak angle is specified directly as an angle or through polar coordinates.

Angle

Specifies the streak direction (0 is horizontal, 90 vertical).

Direction

Specifies the streak direction in polar coordinates (1 0 is rightwards, 0 1 is upwards). If normalize direction is off, these will be multipled by the length to provide the effective length.

Normalise Direction

Whether to multiply the length by the magnitude of the direction vector to provide the effective length.

Units

Sets the effect’s area units.

Image

Sets the length to use units of the Image Space.

Pixels

Sets the blur radius to use units of the number of pixels.

Length

Sets the length of the streaks according to the units set.

Streak Bias

Determines how the streak is centered on the pixel creating the streak. To center the streak around the pixel, use 0. To make the streak end at the pixel, use -1 (the streak comes before the pixel that generates it). To make the streak begin at the pixel, use 1.

Inputs ¶

source

The original layer to which you apply the streakblur effect.

mask

An optional per-pixel mask amount that’s scaled by the Mask parameter.

Outputs ¶

blur

The layer with the streakblur effect applied.
