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 | ||
| Blue (Void And Cluster) | A form of noise, such that the power spectral density is directly proportional to the frequency of the signal. In video, this can be used to dither images, emulating equally spaced points: When blurred, it creates a much more even spread of intensity | Boiling water |  |
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.
