The Directional Blur effect creates a motion blur that pulls and smears the image from one contour edge to a different direction or angle. This effect is useful in creating the impression of speed, such as the streaks of colour that follow a car travelling at high speed. The look of the blur is similar to the look achieved using Gaussian blur when applied with multiple iterations.
- From the top menu, select Layer > Apply Effect > Directional Blur.
- In the Camera or Stage view, right-click on the layer you want to apply the effect to and select Apply Effect > Directional Blur.
|Length||Length of the blur.|
|Width||Thickness of the blur.|
The direction in which the blur is applied, in degrees. At 0°, the blur is applied towards the right.
NOTE You can click and drag on the dial at the right of the field to visually set this angle.
|Bidirectional||Applies the blur on both sides of the pixel.|
|Fall Off||The distance where the blur fades from the edge of the image. Select a value between 0 and 1. A fall-off rate of 0 causes the blur to fade out slowly, distributing the blur evenly from the edge of the character to the farthest edge of the blur. A fall-off rate of 1 causes the blur to fade out quickly, so the blur is heaviest closer to the edge of the image.|
|Number of Iterations||The number of times the blur is applied to the image. A higher number of iterations creates smoother transitions between colours and increases the blur, but also increases render time.|
