The world of video compression is constantly evolving, with new technologies emerging to improve visual quality, reduce file sizes, and enhance the overall viewing experience. In this article, we will delve into the latest video compression technologies, exploring their features, benefits, and applications.
Understanding Video Compression
Before we dive into the latest video compression technologies, it’s essential to understand the basics of video compression. Video compression is the process of reducing the size of a video file while maintaining its quality. This is achieved by removing redundant data, using algorithms to predict and encode the differences between frames, and applying various techniques to reduce the amount of data required to store or transmit the video.
Types of Video Compression
There are two primary types of video compression: lossy and lossless. Lossy compression discards some of the data in the video file, resulting in a lower quality video. Lossless compression, on the other hand, retains all the data in the video file, resulting in a higher quality video.
