Well, the desktop version of Wondershare Repairit provides two methods of video correction. The first is ‘quick repair’ which can fix minor video issues. The second option is ‘advanced repair’, which can be used to repair videos with serious issues such as blurriness, corrupted data, etc. Normally, this tool uses the first option of repair. If the video is severely corrupted, you can use the advanced mode.

Step 1: First open Wondershare.

Then, add the video you want to fix into the cuboid area.

Steps to Fix Pixelated Video Files in the Advance Repair Mode:

Advance Repair allows you to repair corrupted video by adding a Sample file to it. This mode is better suited for several corrupted video files.

A Sample File is a working file that was created from the same device and in the same format as the corrupted file. As a result, Wondershare Repairit uses the data from the functional sample files to fix the damaged files.

Step 1: Add some sample videos taken by the same device.

Method 3: Fix Pixelated Videos with VLC Media Player

Apart from being an open-source and free multimedia player, the VLC media player proves to be a beneficial tool. It has several unique features, such as converting audio and video files to a different format and fixing minor errors in videos. But, it usually only supports a few video file formats, including AVI for repairing. And, if you play an MKV file, it may display the ‘VLC not playing MKV file’ error.

To fix pixelated videos, follow these steps:

  1. Launch the VLC media player on your computer.
  1. Select ‘Preferences’ from the ‘Tools’ menu.

  1. Navigate to the ‘Inputs/Codecs’ tab. Then, select ‘Always fix’. Finally, click ‘Save’ to save the changes.

Method 4: Multimedia Players’ Incompatibility

There is a good chance that the videos are perfectly fine but might be incompatible with the multimedia player you are using. This could result in a grainy or pixelated video. So, right-click on the video and open it in another video player that supports all video formats.

Method 5: Reset the Size to its Initial Setting

Video compression is often used to reduce the size of video files when memory cards are running low on storage space. But, this decreases the quality, resulting in pixelated videos. To start, video conversion is done using online conversion tools, which reduces video quality. I recommend you shift back to the original size and quality to avoid future errors.

Part 3: What Causes A Pixelated Video?

To start with, it is crucial to understand the root causes of why videos are pixelated. Having the exact knowledge can also help you solve the problem of your video not playing.

The general rule for image and video clarity is that the more pixels there are, the clearer the picture or the video will be. The video becomes unclear or not up to standard when the pixel rate is lower. As a result, the video becomes pixelated. Using a defective camera is another reason for pixelation. The quality of the videos may also suffer if the camera lens gets scratched or dirty.

Some other factors that contribute to this issue are shooting videos in low lighting conditions and with a lower aperture setting, and reducing the file size of a video file.


  • Q 1. What is the cause of video pixelation?

  • A1: Pixelation occurs when video files are compressed to make them smaller and use less memory. However, excessive compression may harm video quality.

  • Q 2. Exactly, how do I get rid of pixelation?

  • A2: Using AI-based solutions is the only practical method of addressing pixelation. The edges of a picture are only slightly smoothed out by conventional image editors like Photoshop. This gives the impression of blurriness. Then, using AI that has been trained on millions of images can genuinely recover the details by replacing the mixing pixels.

  • Q 3. How can you prevent the video pixelation problem?

  • A3: You can avoid the problems associated with video pixelation by following the tips:

    1. Use the correct camera settings.

    2. Use lower ISO settings.

    3. Shoot videos in the correct lighting conditions.

  • Q 4. Why is my 4K video pixelated?

  • A4: Your ISO is too high. The image sensors in your smartphone or camera are too small. Moreover, the video compression rate is insufficient.


Without any doubt, watching pixelated videos is boring. No matter how hard you try, it will inevitably happen. The good news is that there is a solution for every issue; you just need to look for it.

In this article, I showed you how to fix pixelated video online for free. From all the methods I mentioned above, Wondershare Repairit is the most recommended for its powerful function. So, without wasting too much time and effort, use this tool to unpixelate your video online.
