But serving the same 20 minute video over torrent is cheap (just get a seedbox and put the content there). Also people don't know how to compress things while retaining quality, a 20 minute video could be under 100MB and still be 4k, especially videos where the majority of the content is just a guy talking on camera. Anime episodes compressed properly tend to be 100-200MB @ 1080 (sometimes < 100) and those have a much harder job than compressing a video with a giy talking in front of a camera about the news (or whatever)
