    Generally, the luminance noise looks more like film grain, while chroma noise looks more unnatural or digital-like. [2] Video denoising methods are designed and tuned for specific types of noise. Typical video noise types are the following: Analog noise Radio channel artifacts High-frequency interference (dots, short horizontal color lines, etc.)
