# double_cup
:contentReference[oaicite:1]{index=1}
## Description
Applies a syrupy, slowed, woozy audiovisual effect reminiscent of “purple drank” aesthetics.
The look emphasizes heavy color bleeding, slowed-feeling motion, chromatic haze, and a dreamlike viscosity often associated with chopped-and-screwed culture or psychedelic video distortion.
## Purpose
`double_cup` is ideal for creators who want to:
- introduce trippy, codeine-inspired visual atmosphere,
- slow or drag the *feeling* of motion without modifying frame rate,
- add soft-focus color diffusion with deep purples and magentas,
- evoke vaporwave, cloud-rap, chopped/screwed, or intoxicated digital moods,
- distort clarity into a smeared, syrup-soaked texture.
## How It Works
1. **Color Drenching**
Highlights and midtones are pushed toward purple, pink, and magenta tones.
2. **Soft Haze / Bloom**
The image takes on a velvety, low-contrast haze that reduces sharp edges.
3. **Viscous Motion Sensation**
Motion may *feel* slower due to subtle temporal diffusion and blending, even if FPS remains constant.
4. **Contrast Flattening**
Dark areas may lift while bright areas smear into a syrup-glow.
5. **Encoding**
Output is written using global Videobeaux codec and quality settings.

## Technical Notes
- The effect pairs best with footage containing midtone gradients or neon lighting.
- Compression interacts strongly with this aesthetic — higher CRF values intensify smearing and color wash.
- Strong purples and pinks may clip if global gamma settings are aggressive; consider pre-processing with `gamma_fix`.
- Works especially well in music video contexts.
## Recommended Usage
- Vaporwave, cloud rap, chopped-and-screwed visuals.
- Psychedelic edits and dream-sequence overlays.
- Live VJ loops and projection-mapped environments.
- Mood-setting transitions between high-energy and slow-motion scenes.
## Quality Tips
- Use a lower CRF (higher quality) to retain smooth haze gradients.
- Combine with `blur_pix` or `bad_contrast` for more degraded, syrup-soaked textures.
- For extreme purple saturation, apply `lut_apply` with a magenta-heavy LUT before this effect.
- If the image feels too dark, pair with `gamma_fix` for lifted midtones before applying `double_cup`.
