The Zoom blur effect creates a radial motion blur that simulates the effect of rapid movement toward or away from a center point, similar to a camera zoom effect or to represent speed.
How it works
The Zoom blur simulates motion by blurring outward from a center point you define. The effect includes a controllable inner radius, allowing you to keep subjects in focus while blurring the surroundings.
Use cases
Zoom blur is effective for:
- Creating the illusion of fast forward movement
- Emphasizing a central subject
- Adding dynamic energy to static images
- Simulating hyperspeed or warp effects
- Creating dramatic transitions
Controllers
| Name | Type | Description | Range |
|---|---|---|---|
| Center | Group | Controls the center point of the zoom effect | - |
| - x | Number | Horizontal position of the zoom center (0=left, 1=right) | 0-1 |
| - y | Number | Vertical position of the zoom center (0=bottom, 1=top) | 0-1 |
| Strength | Number | Controls the intensity of the zoom blur effect | 0+ |
| Inner Radius | Number | Size of the center area that remains in focus | 0-1000 |
| Passes | Number | Number of samples taken along each radial line | 0-100 |
| Gradient Length | Number | Controls how gradually the blur transitions intro the radius | 0-10 |
Creative effect
Try reducing the Passes value to create distinct, noisy-looking rings radiating from the center. This can produce a cool stylized effect that’s different from the smooth blur you get with higher pass counts.
