How Modern Video Compression Algorithms Actually Work

Modern video compression algorithms aren’t the same as the image compression algorithms you might be familiar with. The additional dimension and time means different mathematical and logical techniques are applied to the video file to reduce the size while maintaining video quality. In this post we’re using H.264 as the archetypal compression standard. While it’s no longer the newest video compression format, it still provides a sufficiently detailed example for explaining big-picture concepts about video compression. What Is Video Compression? Video compression algorithms look for spatial and temporal redundancies. By encoding redundant data a minimum number of times, file size can be reduced. Imagine,… Read more
