What Are Pixelated Videos?

Pixels are the smallest unitary elements of a digital image in a video. The more pixels a video has, the higher the quality and resolution of a video file. Pixelated videos appear visually grainy, blurry, and distorted due to displaying irregular shapes and objects such as polygons and square-like pixel blocks.

These irregularities occur due to insufficient information required to run it smoothly in the video file. Instead of a perfect playback, these irregular objects distort the video image, reducing the video's quality and blurring the content captured in every video frame.

Because of that, pixelated videos cause digital eye strain and obstruct the viewing experience for your target audience.

What Causes Pixelated Videos?

The most common cause of video pixelation is incorrect or excessive use of video compression. When you compress a video file, you compress the fragment data in the video itself. Compression can help reduce memory usage by making your video files smaller, but it can also reduce the quality and clarity of your video.

Excessive compression permanently deletes certain portions of file data encoded in the video, creating a grainy and blurry effect on the video called video pixelation. In addition, excessive file compression also downgrades the video's audio quality.

Other common causes of pixelated videos include:

• Media player incompatibility issues – Playing high-bitrate, high-resolution videos with an incompatible media player could result in pixelation due to missing codecs and the inability to support the present video settings.
• Incorrect camera settings – Using improper camera settings, shooting in higher ISO settings, or recording with lower aperture settings will result in pixelated videos.
• Shooting videos in low light conditions – Shooting videos in low light environments require high ISO and wide aperture settings. However, mixing these settings can produce unwanted outcomes, including pixelated videos.

How to Prevent Pixelated Videos

If you shoot a video using the wrong aperture, low-resolution settings, and insufficient lighting, you'll end up with pixelated video files.

Here's how to prevent this:

• Use the correct camera settings – Adjust the camera settings according to your specific requirements to ensure optimal outcomes. Stick to high ISO and wide aperture if you're shooting in low light. If you're shooting during the daylight, go with the opposite.
• Ensure you have adequate lighting – Avoid grainy videos by ensuring you have natural daylight for outdoor shooting or enhanced artificial lighting for shooting at night or indoors.
• Use lower ISO settings – ISO represents the image sensor sensitivity during a video shoot. Using lower ISO settings can help prevent video distortion by avoiding excessive light.
• Stick to the wide aperture – The wider the aperture, the more light your camera captures. If you're shooting in low light conditions, stick to wide aperture settings to avoid video distortion.
