Understanding Pixelation
Pixelation is a phenomenon that occurs when a video is displayed at a lower resolution than its original recording. This can happen due to various reasons, such as low-quality recording equipment, insufficient storage space, or inefficient video compression algorithms. When a video is compressed, the compression algorithm discards some of the data to reduce the file size. If the compression is too aggressive, it can lead to a loss of detail and a blocky appearance, which is known as pixelation.
Causes of Pixelation
There are several factors that contribute to pixelation in videos. Some of the most common causes include:
Pixelation can occur due to the resolution of the recording device. If the device has a low resolution, it will capture fewer pixels, resulting in a blocky or grainy appearance. Additionally, video compression can also lead to pixelation. When a video is compressed, the algorithm discards some of the data to reduce the file size. If the compression is too aggressive, it can lead to a loss of detail and a blocky appearance.
