In regions with expensive data (India, Brazil, parts of Africa) or for users archiving massive libraries of older TV shows (where one episode is ~150-200MB), the 300MB MKV remains the gold standard of efficiency.
Older codecs like x264 (AVC) required more data to maintain visual fidelity. HEVC (H.265) is much more efficient. It can deliver video quality comparable to x264 at roughly half the bitrate. This technological leap allowed encoders to shrink 720p or even 1080p movies into the 300MB range while maintaining a level of quality that is surprisingly watchable on smaller screens like smartphones and tablets. mkv 300mb
It allowed users to store hundreds of movies on a single affordable microSD card or a small hard drive. Mobile-First Viewing: In regions with expensive data (India, Brazil, parts
