# smudge
|
|
|
|
## Description
|
|
Applies a gentle smudge effect to the video, softening edges and pulling colors slightly across motion paths.
|
|
The result resembles a faint manual smear, as if the image were lightly dragged or brushed while still wet.
|
|
|
|
## Purpose
|
|
`smudge` is designed for creators who want:
|
|
- soft, organic distortion without heavy abstraction,
|
|
- a mild “wet paint” or “finger drag” aesthetic,
|
|
- subtle deformation suitable for dreamy or analog-inspired edits,
|
|
- smoothing of harsh edges or digital sharpness,
|
|
- a simple, no-argument effect that can be stacked or used as a finishing texture.
|
|
|
|
## How It Works
|
|
1. **Edge Softening**
|
|
The filter diffuses detail and blends micro-edges, reducing digital crispness.
|
|
2. **Directional Blur/Smear**
|
|
Motion or tonal boundaries smear slightly, giving the impression of a softly dragged image surface.
|
|
3. **Color Bleed**
|
|
Neighboring pixels influence one another to create subtle spreading of hue.
|
|
4. **Encoding**
|
|
Output is then encoded using Videobeaux global CRF, codec, and pixel-format settings.
|
|
|
|
## Program Template
|
|
```bash
|
|
videobeaux -P smudge \
|
|
-i input.mp4 \
|
|
-o output.mp4
|
|
```
|
|
|
|
## Arguments
|
|
- *(No additional program-specific arguments; uses global videobeaux options only.)*
|
|
|
|
## Real World Example
|
|
```bash
|
|
videobeaux -P smudge \
|
|
-i myvideo.mp4 \
|
|
-o smudge_styled.mp4
|
|
```
|
|
|
|
## Program Output
|
|
<video controls preload="metadata" style="max-width:100%; border-radius:8px; margin:1em 0;">
|
|

## Technical Notes
|
|
- Ideal for footage with strong lines or shapes — smudging softens them into painterly contours.
|
|
- Repeated smudging (e.g., applied twice in a chain) can create a watercolor-like wash.
|
|
- Compression artifacts become smoother and less blocky after the smudge effect.
|
|
- Works especially well before color-grading to produce a gentle base texture.
|
|
|
|
## Recommended Usage
|
|
- Dream sequences, surreal atmospheres, or emotional montage.
|
|
- Soft, analog-inspired grading setups.
|
|
- Background layers in collage or Lagkage layouts.
|
|
- Visual art workflows that benefit from painterly distortion.
|
|
- Preprocessing footage before heavy glitch effects to create contrast.
|
|
|
|
## Quality Tips
|
|
- Lower CRF yields smoother, more elegant smudges.
|
|
- Higher CRF adds grit, making the smudge feel more raw or textural.
|
|
- Combine with `slight_smear` for layered organic softness.
|
|
- Use `repainting` afterward for a “hand-redrawn” effect.
|
|
- Upscale with `resize` before smudging if you want especially smooth, flowing distortion.
