White Noise

What is White Noise in Video Editing?

White noise in video editing refers to a random signal having equal intensity at different frequencies, giving it a constant power spectral density. This term is often used in the realm of audio, where it can help to mask unwanted background noise, but it can also be applied to video. In video editing, white noise can be seen as grainy or snowy patterns that appear over a video due to signal degradation or high ISO settings in cameras.

Understanding the Impact of White Noise on Videos

White noise can have a significant impact on the quality of your video. It can cause a distraction and degrade the overall viewing experience. If a video has too much white noise, it can be challenging for viewers to focus on the main subject or storyline.

White Noise Causes

  • Signal Degradation: If the signal between the recording device and the display device is weak or compromised, it can lead to white noise.
  • High ISO Settings: Using high ISO settings in low-light conditions can increase the amount of noise in your video.
  • Compression: Over-compression of a video can also cause white noise as it reduces the video’s quality.

How to Reduce White Noise in Videos

It is essential to know how to handle white noise when it occurs in your videos. Here are some suggestions:

Use Noise Reduction Tools

Several video editing software offer noise reduction tools that can help reduce the appearance of white noise in your videos. Examples of such software include Adobe Premiere Pro and Final Cut Pro.

Adjust Camera Settings

Lowering your camera’s ISO setting can help reduce the amount of noise in your video. However, this may also reduce the brightness of your video, so it’s a delicate balance to maintain.

Proper Lighting

Ensuring proper lighting when filming can significantly reduce the need for high ISO settings, thereby reducing the potential for white noise.


While white noise can potentially degrade the quality of your video, understanding its causes and knowing how to deal with it can significantly improve your video editing skills. By using proper noise reduction tools and filming techniques, you can ensure your videos are of high quality and appealing to your viewers.
