: Highly compressed files designed for mobile viewing without losing significant quality.
At its core, the "300MB" format is an engineering feat of lossy compression. In regions where high-speed fiber is a luxury and mobile data caps are strict, the ability to shrink a two-hour high-definition film into a 300-megabyte container is the difference between consuming culture and being excluded from it.
