Part 1. What Is Video Compression and Why Should You Compress Video?

Video compression is a process that reduces the file size of a video to optimize data storage and transfer. When we post a video, it takes hosting storage resources. The larger the video size, the more storage resources it will take, and it also makes your website load slower, which isn’t good for user experience. That’s why we need to compress videos to reduce their cost for storage or transmission.

There are two types of video compression: Lossy compression and lossless compression. The former reduces your file size by removing some of the original data, which makes the video even smaller but downgrades its visual quality, while the later compresses video without losing quality by removing only unnecessary metadata. Lossless compression typically results in larger file sizes compared to lossy compression, but it is perfect for situations where maintaining high visual fidelity is crucial.
