How to Fix Pixelated Videos or Grainy Videos: A Step-by-Step Guide

Pixelated or grainy videos can ruin the visual experience, making them less engaging and professional. Whether you’re dealing with poor resolution, compression issues, or low-light conditions, learning how to fix pixelated videos can save your content. This guide explores effective tools and techniques, such as UniConverter AI Video Enhancer, to unpixelate a video or fix grainy videos for improved quality.

Section 1: Understanding Pixelation and Graininess in Videos 

Pixelation occurs when a video has a low resolution, causing individual pixels to appear visibly large, especially on larger screens. This often happens due to compression or scaling issues. On the other hand, graininess refers to the visual noise that appears in videos shot in low-light conditions or with inadequate camera settings. Both pixelation and graininess significantly affect the clarity and professionalism of your video content, reducing its appeal. Fortunately, advanced tools like Wondershare UniConverter and AI Video Enhancers are designed to address these issues, enabling you to enhance resolution, reduce noise, and restore your videos to pristine quality.

Method 2. Fix Pixelated Videos with After Effects

Adobe After Effects is a powerful tool designed for professional video editing and post-production. It provides advanced effects and settings to fix pixelated videos by smoothing out jagged edges and enhancing clarity. With its wide range of features, you can achieve high-quality results, making it an excellent choice for fixing pixelation in videos.

Steps to Fix Pixelated Videos Using Adobe After Effects:

Step 1: Import Your Video
Launch Adobe After Effects and create a new project. Import the pixelated video by dragging it into the project panel or selecting “File” > “Import.” Drag the imported video onto the timeline to begin editing.

Step 2: Apply a Blur Effect
Go to the “Effects & Presets” panel and search for the “Gaussian Blur” effect. Drag and drop it onto the video clip in the timeline. This effect helps to smooth out harsh pixelated edges. Adjust the blur intensity by increasing the “Blur Radius” value until the pixelation becomes less noticeable. Be cautious not to overdo the blur, as it might make the video appear too soft.

Step 3: Sharpen the Video
To restore the details after applying the blur, add a “Sharpen” effect. Search for “Sharpen” in the “Effects & Presets” panel and apply it to the same video clip. Adjust the “Amount” slider to enhance the edges and improve the overall clarity. Balance the blur and sharpen effects for the best results.

Step 4: Render and Save
Once you’re satisfied with the edits, render and save the video in high resolution. Go to “Composition” > “Add to Render Queue,” choose your preferred output settings, and click “Render.” Save the file in your desired format and resolution, such as HD or 4K, to ensure the best playback quality.

By combining blur and sharpen effects, Adobe After Effects allows you to effectively fix pixelation and produce a polished, professional-quality video.

Method 3. Fix Grainy Videos with VLC Media Player

VLC Media Player is not just a video player but also a versatile tool for basic video enhancements. It includes a “Denoise” filter to help reduce graininess in videos, making it a convenient option for quick fixes without requiring professional software. Best of all, it’s free and works on most platforms.

Steps to Fix Grainy Videos Using VLC Media Player:

Step 1: Open the Video in VLC
Launch VLC Media Player and load the grainy video you want to improve. You can do this by clicking on “Media” > “Open File” and selecting the video from your device. Ensure the video is playing to preview the changes as you make them.

Go to the menu bar and click on “Tools” > “Effects and Filters.” In the pop-up window, navigate to the “Video Effects” tab. This section contains various tools to adjust video properties, including brightness, contrast, and noise reduction.

Step 3: Reduce Noise
Within the “Video Effects” tab, locate and enable the “Denoise” filter. Adjust the denoise slider to reduce the graininess in your video. Start with a low setting and gradually increase it until the graininess is less noticeable. Be mindful not to overuse the filter, as excessive denoising can make the video appear unnatural.

Step 4: Save Your Settings
After applying the denoise filter, save the improved video. To do this, use VLC’s conversion feature:

1. Go to “Media” > “Convert/Save.”
2. Add your video file, click “Convert/Save,” and choose a destination file.
3. In the “Profile” settings, ensure the adjustments are preserved and select the desired output format (e.g., MP4).
