Noise, also known as Static is a video and audio distortion technique that involves 'fuzzing' of the footage.
This is often seen in analog distortion effects and re-creations.
Types of Noise
There are five major types of noise. https://en.wikipedia.org/wiki/Colors_of_noise
| Color | Technical Description | Sounds Like | Looks Like | Usage |
|---|---|---|---|---|
| White | Example | Radio Static | MNoiseGenerator | |
| Purple | Example | Example | ||
| Red (Brownian) | Example |  |
||
| Pink (Fractal) | Noise with a frequency spectrum such that the power spectral density (power per frequency interval) is inversely proportional to the frequency of the signal | A waterfall |  |
Fractal Noise in After Effects |
| Grey | Example | Example |
Usage
Digitally
The process of adding noise to audio or video are practically identical; most of the time, you simply need to apply an effect that adds it in for you.
Video Effects
- Noise HSL and its variants in Premiere Pro and After Effects
- Add Noise and Film Grain in Vegas.
Via Analog Distortion
Adding static to an analog signal is as simple as messing with the signal itself - putting things in the way, magnets, moving it too far away/weakening the signal, etc.
