# Motion Blur

> Add transform motion blur to FX layers in the project.

Motion blur softens movement on FX layers. It applies across the project, not to a single clip.

**1. Open Motion Blur**

Select **Settings** on the tool rail, then **Motion Blur**.

**2. Turn it on**

The panel says "Apply transform motion blur to enabled FX layers across the project." Turn on **Enable Motion Blur**.

**3. Set the shutter**

| Control | Starting value | What it changes |
| - | - | - |
| Shutter angle | 180 | How long the shutter stays open. A higher angle smears motion more. |
| Shutter phase | -90 | Where that smear sits relative to the frame. |
| Samples per frame | 16 | How many samples build the blur. |
| Adaptive sample limit | 128 | The upper sample count when the blur needs more detail. |

Play the section with the moving FX layer and raise samples only if the streak looks stepped.
