Full Guide on How to Denoise Video Using an AI-Powered Tool

Video noise refers to grainy or static-like patterns appearing in video frames. It is typically caused by insufficient light received by the camera sensor, excessively high ISO (International Organization for Standardization) settings, or internal electronic interference within the sensor. Noise becomes particularly noticeable when the sensor cannot capture enough photons to generate a sharp signal, especially in shadow areas.

Video noise significantly degrades overall video quality and clarity, distracting viewers. Fortunately, modern AI-powered video noise reduction technology can intelligently analyze video and remove noise while preserving detail, thus restoring the video quality.

What Is Video Denoise and Video Denoiser

Video denoising refers to the process of removing unwanted noise and grain from videos to create cleaner, sharper, and more professional-looking videos. Modern video denoising technology relies on artificial intelligence. Video denoisers are software or plugins that use these advanced AI technologies to remove video noise.

How to Denoise a Video

This section outlines the key considerations for choosing an AI video denoiser and explains how to use MiniTool Video Converter (a free video denoise software) to remove video noise.

How to Choose the Right Video Denoiser

Choosing the right video noise reduction tool can streamline the workflow and improve efficiency. Here are several factors worth evaluating during the selection process:

1. High Detail Retention: High-quality noise reduction tools remove noise while preserving texture details such as hair and skin tone. Avoid tools that produce overly smooth effects.
2. Performance and Speed: Fast processing speed is crucial for video denoising. Insufficient processing speed will reduce overall efficiency.
3. Price: Evaluate whether the video enhancer is free or if a subscription fits your budget. It’s best to choose a tool that offers free video enhancement options.

Taking the above three aspects into account, I ultimately chose a video enhancer that preserves the original details and has a fast processing speed: MiniTool Video Converter.

After using the Video Enhancer feature of MiniTool Video Converter, the video noise was significantly reduced.

Difference Between Noise and Grain

When discussing video denoising, many people confuse noise and grain. Visually, both of them appear grainy, but they are not the same thing.

Noise refers to unwanted digital interference that occurs when recording video in low-light conditions. It usually appears as colored specks. Grain, also called film grain, is a visible grainy texture in video. These grains often resemble fine organic grains or sand grains and are generally considered more aesthetically pleasing. Noise degrades image quality, while film grain is often associated with a vintage style.

Besides, the sources and distribution of noise and film grain are quite different. Digital noise originates from sensor interference and is often concentrated in shadow areas, while film grain is caused by physical silver halide particles formed during the developing process, which are usually more noticeable in midtones and highlights.

Tips on How to Avoid Video Noise

To minimize video noise during recording, keep the following key points in mind.

1. Increase Lighting

Ensure sufficient lighting during shooting. A well-lit environment allows the sensor to capture clear, detailed images, reducing the need for camera light compensation.

2. Lower ISO

ISO determines the sensor’s sensitivity to light, but higher ISO values ​​result in significant image quality loss. Therefore, lowering the camera’s ISO setting as much as possible can reduce digital noise.

3. Use a Wide Aperture

In low-light conditions where adding additional lighting is inconvenient, open the lens aperture to increase the amount of light entering the camera, thereby lowering the ISO setting. This is also a way to reduce digital noise.

Bottom Line
