# bad_predator
|
||
|
||
## Description
|
||
Applies a stylized “bad Predator heat vision” effect to the input video.
|
||
This intentionally degraded thermal-vision look mimics the broken or low-budget interpretation of the thermal-view used in the *Predator* films — surreal color distortion, thermal-like banding, exaggerated edge detection, and unstable gradients.
|
||
|
||
## Purpose
|
||
`bad_predator` is designed for creators who want to:
|
||
- add a faux–heat vision aesthetic,
|
||
- produce psychedelic or thermal-like color distortions,
|
||
- disrupt realism with genre-coded VFX,
|
||
- introduce mood, abstraction, or sci-fi ambience,
|
||
- create an intentionally *wrong* or glitchy interpretation of cinematic thermal vision.
|
||
|
||
## How It Works
|
||
1. **Thermal Color Remapping**
|
||
The video is transformed into an artificial temperature-based palette, often with exaggerated reds, blues, greens, and neon ranges.
|
||
2. **Edge Boosting & Gradient Distortion**
|
||
Edges may “glow,” flatten, or warp, imitating digital thermal sensors or corrupted color channels.
|
||
3. **Contrast Folding**
|
||
Shadows and highlights are redistributed into stylized color bins rather than natural brightness patterns.
|
||
4. **Encoding**
|
||
Output is encoded using global Videobeaux settings (codec, CRF, pixel format).
|
||
|
||
## Program Template
|
||
videobeaux -P bad_predator \
|
||
-i input.mp4 \
|
||
-o output.mp4
|
||
|
||
## Arguments
|
||
- *(No additional program-specific arguments; uses global videobeaux options only.)*
|
||
|
||
## Real World Example
|
||
videobeaux -P bad_predator \
|
||
-i myvideo.mp4 \
|
||
-o bad_predator_styled.mp4
|
||
|
||
## Program Output
|
||
<video controls preload="metadata" style="max-width:100%; border-radius:8px; margin:1em 0;">

||
## Technical Notes
|
||
- The effect is purely stylistic — not physically accurate thermal imaging.
|
||
- Works best on footage with strong silhouettes or motion, where thermal-emulated contrast is most visible.
|
||
- If the global pixel format is set to low bit depth (e.g., 8-bit), banding interacts strongly with the effect, enhancing the “bad thermal” look.
|
||
- Use `chain_builder` to combine with other stylized processes for multi-layer sci-fi or horror visuals.
|
||
|
||
## Recommended Usage
|
||
- Music videos, experimental film, and glitch-aesthetic sequences.
|
||
- Sci-fi projects referencing Predator-style heat vision.
|
||
- Stylized surveillance overlays or false-sensor aesthetics.
|
||
- Abstract color grading for live visuals or performance art.
|
||
|
||
## Quality Tips
|
||
- Apply before compression-heavy steps to preserve the color distortions.
|
||
- Combine with `bad_contrast`, `hash_fingerprint`, or `bad_animation` for a fully degraded sensory aesthetic.
|
||
- Use lower CRF values to avoid washing out the neon tonal ranges.
|
||
- Consider pairing with `gamma_fix` to stabilize midtone visibility before applying the effect.
