What is video compression?

Video compression is the process of reducing the size of a digital video file by removing redundant or unnecessary data. This makes it easier to store and transmit videos over the internet or between devices without significantly sacrificing quality. There are two main types of compression: lossy, which discards some data to reduce file size, and lossless, which preserves all the original information. Common video compression standards include H.264, H.265 (HEVC), and VP9. Efficient video compression is crucial for streaming, broadcasting, and video conferencing applications.
