Having a noisy or grainy video after you’ve done your best to capture clear footage can be a total bummer. The quality of your video can significantly impact viewer engagement and the overall professional appeal of your content. For this issue, you will need a video editor that can remove background noise effectively.
While overcoming background noise may be a tricky task, these editors can make a significant difference in enhancing your video quality with ease. Learn more about how to remove background noise from video and find out what you need to know about background noise and how to tackle the issue in our discussion below.

Part 1. Different Types of Background Noise in Videos
Noise in videos comes from a few sources, mainly the sensor and the analog-to-digital conversion process. There are two main types of noise: internal and interference.
Internal Noise
This type of noise comes from within the camera and is caused by factors like electricity, heat, and light levels. Common types include:
- Gaussian Noise: Appears as constant fluttering, often blue, in underexposed frames where ISO is high.
- Fixed-Pattern Noise: Results from sensor manufacturing flaws, causing different pixels to have varying sensitivity.
- Salt and Pepper Noise: Shows as randomly bright or dark pixels, similar to dead pixels but occurring randomly.
- Shot Noise: Causes "blockiness" in shadows of underexposed or over-volted shots and can escalate to Salt and Pepper noise.
Interference Noise
Interference Noise is caused by external factors like strong radio transmissions. It's less common in modern cameras but can still affect the final image. Some of the common types include Periodic noise, which usually appears as a fixed pattern overlay on top of the desired image.
Part 2. When Should I Remove Background Noise from Video?
Removing background noise from videos is often necessary to improve clarity and overall viewer experience. But sometimes, the noise in a video is used deliberately for aesthetic purposes, especially if you want to achieve a vintage or gritty look. This intentional use of noise can add character and atmosphere to the footage.
So, when should you remove background noise from a video? Usually, image noise comes when you are shooting on one of the scenarios below:
- Videos that are shot in low light, especially in darker areas of the frame.
- Underexposed footage that is underexposed may be noisy when brightened in post-processing.
- Videos that have been heavily compressed (such as for streaming or online sharing).
- Outdoor night shots
In short, the decision to remove background noise should consider its impact on the video. You need to remove background noise when it distracts from the main content or detracts from the professional quality of the video.
In the next section, we will give you recommendations for video editors that can remove background noise from a video.
