Video Coding Basics - How is this so efficient?

Ever wondered how video coding works on the insides? I mean you might have used some video encoders and decoders but what is under the hood in the intestines of these modules? I am not going into detail on any specific codec but I try to cover the basic building blocks of encoders and decoders which are common to all popular video coding standards like h.264/AVC, h.265/HEVC, VP8, VP9, AV1 or even h.266/VVC. So after watching this you hopefully know the basics of how it is even possible to transmit stunning looking high quality video at such incredibly low bitrates.
