5 Common Types of Video Noise [With Samples]
Here are some common types of video noises you must know in order to record a glitch-free video.
1). Digital Noise & Flickers
Digital cameras’ sensor limitations, severe grains, high ISO settings, and low-light conditions, all these issues could explain why your videos are always full of digital noise and flickers.

2). Block Noise & Mosquito Noise
Compression is the ENEMY. Yes, sometimes, it's inevitable to compress a video, but over-compression results in video noise, which is called block noise.
Ever seen a low-quality video? You must have seen ugly pixel blocks around either subtitles or any fast-moving object. It's because of the compression.

Mosquito noise is also a result of over-compression. You must have seen it in low-quality extra-compressed YouTube videos. Those faint little artifacts that seem to buzz just like a mosquito can be noticed in the darker areas of highly compressed videos.

3). Dynamic Noise
You'll experience a pixelated grain every time when the light is low. This degrades all the shadows and darker tones in the video, known as Dynamic Noise.
So that’s why we say dynamic noise is all about LIGHT. The more the light fluctuates, the more thriving the dynamic noise will be.

4). Exposure Noise
Filmmakers aim for crisp motion. But is it possible to do it with an improper shutter speed? Nope. Especially when shooting an action-packed scene, it is the shutter speed that promises a non-blurred smooth, and fast motion. In case of an incorrect shutter speed, one will experience exposure noise.

Exposure noise simply means blurred and distorted frames. The way to fix it is just to take care of the shutter speed.
Mainly in high-speed scenes, to ensure a higher shutter speed. For example: 1/120s for 60fps.
5). Low-Resolution Noise
Due to low-bitrate encoding and poor upscaling, you may experience unwanted grain in those old videos.
Now, what about the 90’s old videos, can they be recovered? Of course! Never mind how unclear the details are, some AI video denoise softwares can beat low-resolution noise.
