Video noise is often characterized by a buzzing pattern that rapidly shifts from one frame to the next. To illustrate this clearly, we included some real-world examples below.

Noise typically appears in low-light conditions, such as nighttime, dusk, indoor settings, or cloudy days. Higher-quality cameras, which tend to be more expensive, generally produce videos with less noise due to their larger sensors and lenses that allow for greater light capture.

In contrast, mobile devices have significantly smaller sensors and are more susceptible to noise when lighting conditions are not ideal (e.g., indoors or on cloudy days). Zooming into a photo taken indoors with your phone will clearly illustrate this issue.

To determine if you need to apply the noise reduction filter, please open the video in your preferred video player and play it. If you notice a subtle buzzing pattern, we recommend using the noise reduction filter.

Noise and grain look very similar, but are caused by different things.

Grain is typically associated with older film formats like 32mm, 16mm, and 8mm. It's a characteristic element that contributes to the unique "film look" and is generally considered desirable.

In contrast, noise is unwanted and occurs when the camera signal is disrupted. Unlike grain, which is almost always colorless, noise can manifest in color.

The left side of the picture shows grain, while the digital noise is on the right. You can clearly see the noise has color, while grain has no color.
