Standard 480p or 720p episodes of a 22-minute sitcom usually range from 150 MB to 400 MB. A file uses aggressive compression to reduce that size by nearly 70–80%.

The MKV (Matroska Video) format was a revelation. Unlike the clunky AVI container, MKV was flexible and supported advanced compression codecs like H.264. Encoder groups—internet heroes who remain largely anonymous—began experimenting with aggressive compression techniques. They realized that by resizing 720p video to something closer to 480p (or even 360p), lowering the bit rate, and using highly efficient audio compression (often AAC), they could shrink a 40-minute sitcom episode down to an astonishing 60 to 70 MB.
