If you have ever played a video that intermittently shows "polygon" like objects, that, my good friend, is what pixelation looks like. It frustratingly diminishes the quality of the video.

Nobody likes to watch a movie with polygons competing with actors for screen time-just a little joke. Once you get the hang of it, fixing pixelated videos is not exactly rocket science.

What Causes Video Pixelation?

Pixelation usually happens when you compress the data in video files to make the video files smaller and reduce memory usage.

This excessive compression, however, could negatively affect video quality. Some of the data encoded in the video are permanently erased, thereby creating the "pixelation" effect on the video.

But what can cause the video pixelation? There are several factors.

  • Shoot videos in low lighting conditions.
  • Use improper camera settings combination.
  • Shoot videos with a lower aperture setting.
  • Shoot videos in higher ISO settings.
  • Shoot videos with a camera that has a small sensor.
  • Convert a video file with tiny file size.

In most cases, pixelated videos can be repaired. Nevertheless, there are some extreme cases where it becomes impossible to fix the videos in any way.

It seems then that the only possible solution is to reduce the size of your playback window. This inadvertently reduces the grains and improves video clarity.


4 Methods to Fix Pixelated or Grainy Videos

Pixelated or Grainy videos are quite irritating as they make the video viewing experience less enjoyable. There are many reasons why your video footage may look grainy, but fortunately, there are several methods that allow you to rectify such errors.

So, sit back and relax as you are giving a guided tour on how to fix grainy videos.

Method 1. Recover from Original Video File

If it is the excessive levels of compression that result in pixelation, one way can help you. You could create a new video file provided that you have access to the original video file.

Simply discard the pixelated video and save the original video file with a lower level of compression. That should do the trick.

Method 2. Limited Hardware Processing Capacity

Sometimes, the problem is not necessarily with the video, but with the hardware processing the video. High-resolution videos consume significant computing resources. They will appear pixelated if the videos being played exceed the processing capacity of the hardware being utilized.

In this instance, the videos are not the culprits. The only solution would be to utilize a system that can handle such videos.

Method 3. Incompatible Video Player

When you are sometimes faced with a pixelated video, it might be a problem with the video player's incompatibility, rather than a problem with the video.

In some instances, videos are encoded with unique algorithms that make certain video players unable to render them efficiently.

You could try using a different video player to confirm if it plays the video without issues.

Method 4. Use Wondershare Repairit Video Repair Tool

Wondershare Repairit Video Repair is an advanced video repair tool that allows for the repair of corrupted videos caused by compression and many other issues. It can quickly rectify grainy, frozen, blurry, or flickering videos with a click of a button.

Bonus Tips Against Pixelated or Grainy Video

We usually refer to a pixel as the smallest unitary component of a digital image. The more pixels used to represent an image, the higher the resolution and quality of a video or image file.

The image resolution is the information an image or video holds. A higher resolution means more info the digital file contains.

If you capture a video in a dark environment or with a camera that has low-resolution footage, pixelated videos can occur. If you compress it to tiny file size or a low video resolution, it can also happen.

All essentially mean is that not enough information is present in the video file for it to run perfectly. You can prevent the problems associated with video pixelation by doing the following:

1. Ideal Lighting Conditions

Well, shooting videos in the correct lighting conditions may seem a bit too obvious. However, having adequate lighting is vital if you want to avoid grainy videos.

When shooting videos outdoors, natural daylight is perfect enough. When shooting indoors or at night, you can enhance the natural lighting with adequate artificial lighting.

2. Using the Correct Camera Settings

Prevention, as it is said, is always better than cure. It is especially true when shooting videos, as avoiding the situations that may create pixelated videos in the first place can save you from a lot of problems afterward.

The use of correct and ideal camera settings is your best bet in avoiding pixelated videos.

3. Using Lower ISO Settings

ISO in a camera measures the sensitivity of the image sensor. When shooting videos, it is always advisable to use a lower ISO setting. It can avoid excessive light from distorting your videos.

But there is a particular case. When shooting in low light conditions, it may be necessary to increase ISO to compensate for the lower lighting level.

4. Wide Aperture

The camera aperture determines the extent of light that enters your camera. In low light conditions, set your camera to wide aperture settings and reduce any possible distortion to your video.


Conclusion

Those evil polygons turn up and flood your video screen with their unwanted appearances. It is certainly not the best experience when you play a video.

But it's not all gloom as the pixelation can be fixed in most cases. With the use of the right software, like Wondershare Repairit, pixelated video files can easily be repaired.
