Blur applies a Gaussian blur with a bounded radius at the source resolution.
What it does#
The radius is in pixels at the source size, from 0 to 64; 0 passes the picture through. It processes every stream of the input at that stream's size and keeps the stream count.
When to use it#
Use it to soften a background, hide detail or smooth a key edge.

Parameters#
| Parameter | Label | Range | Default | Unit | Scale | Notes |
|---|---|---|---|---|---|---|
radius | Radius | 0 to 64 | 8 | px | linear | Blur radius in source pixels; 0 passes the picture through. |
Radius (radius)#
Blur radius in pixels, from 0 to 64.
Tips#
- Radius is bounded so the cost stays predictable.
- Video needs the browser's WebGPU video engine. The Player and exports do not run video yet and report it unavailable. To see a video output, bind a live Screen in the Frame to it.
