# repainting
|
|
|
|
## Description
|
|
Applies an artistic “repainted” effect that makes each frame appear as if it has been smeared, redrawn, or blurred by an alcohol-washed brush.
|
|
The result resembles wet ink, soft smudging, streaked pigment, or repeated overpainting — giving the footage a tactile, analog, hand-altered feel.
|
|
|
|
## Purpose
|
|
`repainting` is designed for creators who want:
|
|
- a painterly, reworked, or smeared aesthetic,
|
|
- a hand-drawn or alcohol-wet look without using frame-by-frame animation,
|
|
- soft organic distortion that feels handmade rather than digital,
|
|
- degraded yet artistic texture for music videos or collage,
|
|
- a simple effect that produces expressive motion smearing.
|
|
|
|
## How It Works
|
|
1. **Frame Reinterpretation**
|
|
Each frame is processed as if it were being redrawn or wiped over with semi-wet pigment.
|
|
2. **Smudge + Alcohol-Wash Simulation**
|
|
Highlights bloom, shadows soften, and edges blur as if dissolved by solvent.
|
|
3. **Temporal Softening**
|
|
Minor streaks or trailing may appear due to repeated repainting across frames.
|
|
4. **Encoding**
|
|
Output is encoded using global Videobeaux settings (codec, CRF, pixel format).
|
|
|
|
## Program Template
|
|
```bash
|
|
videobeaux -P repainting -i input.mp4 -o output.mp4
|
|
```
|
|
|
|
## Arguments
|
|
- *(No additional program-specific arguments; uses global videobeaux options only.)*
|
|
|
|
## Real World Example
|
|
```bash
|
|
videobeaux -P repainting \
|
|
-i myvideo.mp4 \
|
|
-o repainting_styled.mp4
|
|
```
|
|
|
|
## Program Output
|
|
<video controls preload="metadata" style="max-width:100%; border-radius:8px; margin:1em 0;">
|
|
<source src="https://github.com/user-attachments/assets/1770144d-4448-4719-8ef3-e44b720ec857" type="video/mp4">

## Technical Notes
|
|
- Works especially well on footage with bold shapes, faces, or brush-like motion paths.
|
|
- High-contrast imagery yields more pronounced smearing.
|
|
- Compression may increase the “wet paint” feel by interacting with soft, blended regions.
|
|
- Repainting is non-destructive in timing — cadence stays intact even while textures distort.
|
|
|
|
## Recommended Usage
|
|
- Abstract or painterly music videos.
|
|
- Alcohol-ink inspired motion design.
|
|
- Narrative moments needing dreamlike or smeared transitions.
|
|
- Experimental cinema and visual collage.
|
|
- Live VJ loops that benefit from organic, evolving texture.
|
|
|
|
## Quality Tips
|
|
- Lower CRF values maintain smooth, fluid repainted strokes.
|
|
- Higher CRF adds grit, giving the effect a rougher, stained appearance.
|
|
- Combine with `double_cup` for a liquified wash; combine with `blur_pix` for soft surface blending.
|
|
- Apply before LUTs if you want the grade to unify the smear colors; apply after LUTs if you want the smear to distort the grade itself.
|
|
- Up-scaling beforehand using `convert_dims` can produce smoother brush-like textures.
