| Properties | ||
 |
Strength | The strength of the blur (use zero for no blur) Range: 0 to 1; Default: 0.15 |
 |
Angle | The angle of the blur (0º is horizontal) Range: 0º to 3600º; Default: 0º |
Usage
Add Directional Blur to any layer, then adjust Strength and Angle to taste.
⚠️ Heavy Effect
Blur effects require more computational power to render than normal effects in Alight Motion. Depending on the performance of your device and the settings you use for this effect, it may result in preview lag, especially with higher values for Strength, or if you use effects like this with many layers simultaneously or apply multiple heavy effects to the same layer.
Use Cases
- Motion Blur Approximation: This can be used to approximate motion blur for type of animation that don't support the Motion Blur effect directly, such as motion of 3D shapes.
- Glint/Shine: Start with a photo or video layer. Duplicate the layer twice so you have three copies of the layer in total. The bottom-most layer will remain unchanged. For the upper two layers, set their blending mode to Screen, then use Luma Key to isolate the light parts of each layer. Finally, add Directional Blur to each layer, adjusting Angle so that the blur of layer is offset 90º from the other layer.
- Textured Streaks: Apply Noise or Block Noise to a layer and turn Freeze and Monochrome on, then apply Directional Blur to the layer.
- Marbling or paint swirl: Apply Noise or Block Noise to a layer and turn Freeze and Monochrome on, then apply Directional Blur to the layer. Finish by applying Turbulent Displace. To animating paint motion, use keyframe animation with the Evolution, Parallax or Offset properties of Turbulent Displace.
