This is a pretty unkind reading. The author almost surely was using zip as a synonym for compress. Some people use "hoover" as a proxy for vacuum, even though they're not literally using a Hoover vacuum to clean. Movies aren't "escaping" the Shannon entropy limit, they're falling well within the Shannon entropy limit for the appropriate domain of human vision. Whether it's throwing out high frequency noise at one stage or using moving blocks and keeping delta changes at another, there's an underlying assumption of the "codeword" space is versus the source space. Even by the time it gets to the codec it's already "compressed" by throwing out almost all the spectra not visible to us. These are implicit assumptions about the domain that you've dismissed.
