Fix Pixelated Grainy Videos

Part 1. Pixelated & Grainy Videos: Explanation and Their Causes

What Are Pixelated & Grainy Videos?

A pixelated video is one where you can see visible square blocks or broken edges instead of smooth details. This gives the footage a blurry, blocky, and low-resolution look. On the other hand, a grainy video often shows tiny specks or visual noise, especially in dark scenes or low-light conditions. Both pixelation and grain make your footage appear unclear and unprofessional.

To fix pixelated or grainy videos, you can use an AI video enhancer to upscale video resolution, restore lost details, and reduce noise automatically, making the video sharper, cleaner, and more realistic.

Causes of Pixelated & Grainy Videos

Pixelation and graininess usually occur due to low resolution, excessive compression, or poor recording settings. When a video is heavily compressed, many image details are lost, and each pixel becomes more noticeable. Low lighting, high ISO levels, or old camera sensors can also introduce digital noise, leading to a grainy video effect.

To prevent these issues, always record in high resolution, avoid over-compressing during export, and enhance your footage later using AI-powered video restoration tools to maintain professional-quality visuals.
