It really is mind blowing to see how much smaller a file with newer compression can be. Had to convert some videos to a codec that would work on my kids chromebook recently. What was a 300 meg video ballooned up to 2 gigs. One of the videos was 130 megs that jumped up to 3.2 gigs. Time lapse video, so I'm sure it had some of the sweet spots for compression. Still, was dramatic how much a modern codec can get that down.
