If you have ever played a video that intermittently shows "polygon" like objects which frustratingly diminishes the quality of the video, that, my good friend, is what is pixelation looks like. Nobody likes to watch a movie with polygons competing with actors for screen time-just a little joke.

Despite being a common problem, the process of fixing pixelated videos is not well understood by many. Once you get the hang of it however, fixing pixelated videos is not necessarily rocket science.

Part 1: What causes video pixelation?

Pixelation usually happens when data in video files are significantly compressed in order to make the video files smaller and reduce memory usage.

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

Some of the factors that can cause pixilation have been detailed below:

  • Videos that are shot in low lighting conditions.
  • Improper camera settings combination
  • Videos shot with a lower aperture setting
  • Videos shot in higher ISO setting
  • Shooting videos with a camera that has a small sensor
  • Converting a video file with a very small file size

While in most cases, pixelated videos can be repaired, there are extreme cases where it becomes impossible to fix the videos no matter what is done.

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.

Part 2: How to Fix Pixelated or Grainy Videos

Pixelated or Grainy videos are quite irritating as the make the video viewing experience less enjoyable. There are a lot of reasons why your video footage may look grainy but fortunately, there are 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

1. Recovery from Original Video File

If your pixelated video is as a result of excessive levels of compression, you could easily 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

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 and would appear pixelated if the videos being played exceed the processing capacity of the hardware being utilized.

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

3. Incompatible Video Player

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

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

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

How to Fix Grainy Video Files in Advance Repair Mode

This mode is more suited to video files that are severely corrupted. Advance Repair accordingly allows you to repair it by adding a Sample File to it. A Sample File is a working file created from the same device and of the same format as the corrupted file.

Recorverit consequently uses the information from the working sample files and repairs the corrupted files. Follow the steps below to repair your video in this mode:

Step 1. Add some sample videos shot by the same device.

Part 3: Bonus Tips Against Pixelated or Grainy Video?

A pixel is usually referred to as the smallest unitary component of a digital image. The more pixels used to represent an image, the greater the resolution of the image and ultimate the quality of the image or video file.

The image resolution is the information an image holds and the higher the resolution, the more information the image holds.

Pixelation can thus occur if a video is captured using a camera that captures low-resolution footage, shooting in very low light or converting a movie file with a very small file size or very low video resolution.

What all these essentially mean is that not enough information is present in the video file for it to run perfectly. You can Prevent some the problems associated with Video Pixelation by doing the following:

  • Ideal Lighting Conditions
  • Well, shooting videos in the correct lighting conditions may seem a bit too obvious but having adequate lighting while shooting videos is vital if you want to avoid grainy videos. When shooting outdoors, natural daylight is epitome but when shooting indoors or at night, natural lighting needs to enhanced with adequate artificial lighting

  • Using the Correct Camera Settings
  • Prevention as it is said is always better than cure, this 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 afterwards.

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

  • Lower ISO
  • ISO in camera measures the sensitivity of the image sensor. When shooting videos, it is always advisable to use a lower ISO setting in order to avoid excessive light from distorting your videos. Although when shooting in low light conditions, it may be necessary to increase ISO in order to compensate for the lower level of lighting.

  • Wide Aperture
  • The camera aperture determines the extent of light that enters your camera. In low light conditions, it is advisable to set your camera to wide aperture settings in order to reduce any possible distortion to your video.

It is certainly not the best experience when you play a video and those evil polygons turn up and flood your video screen with their unwanted appearances but it's not all gloom as the problem of pixilation can be fixed in most cases. With the use of the right software, like Recoverit, pixelated video files can easily be repaired.

Case: I fixed my grainy videos, but just found some other videos that were playing choppily.
Fix: The solutions to choppy, jerkky or skipping videos.
