## Visual Effects

### Background Color (`b_{color}`)

Set background color for padded areas or transparent videos:

```
tr-b_ff0000         # Red background
tr-b_000000        # Black background
tr-b_ffffff        # White background
```

* Accepts hex color codes without '#'
* Commonly used with:
  * `c_pad` crop mode
  * Videos with transparent areas
  * Letterboxing/pillarboxing areas

### Blur Effect (`blur_{radius}`)

Apply Gaussian blur effect to video:

```
tr-blur_10            # Light blur
tr-blur_50            # Medium blur
tr-blur_100           # Heavy blur
```

Features:

* Radius range: 1-100
* Lower values for subtle effect
* Higher values for strong blur
* Applied consistently across frames

Common uses:

* Background videos
* Privacy protection
* Aesthetic effects
* Content warnings

### Background Blur (`b_blur`)

Create blurred padding from video content:

```
tr-c_pad,b_blur       # Blurred edges from video content
```

Features:

* Uses video content for blur effect
* Maintains visual consistency
* Works with padding operations
* Smoother than solid colors
