By reducing the file size, … Video and audio compression works very differently. Unlike with text where you can have lossless compression, and no data is lost, with images we have what’s called “Lossy Compression” where you do lose some data. And the more you compress, the more data you lose. This is what leads to those horrible-looking … See more To answer that question would involve explaining some very complicated math, certainly more than we can cover in this article, but you don’t need to understand precisely how it works … See more Video works a bit differently from images. You’d think that they would just compress each frame of video using JPEG, and they certainly do that, but there’s a better method for video.
