Zooming out, I discovered a web of contributors. One was an enthusiast who ripped a Blu-ray, re-encoded it to fit streaming bandwidth limits, and married NinaSub's .ass file with forced subtitles for Korean on-screen text. Another was a moderator of a subtitle review group, who ran blind tests: volunteer viewers compared five subtitle tracks without knowing their authorship, then rated clarity, faithfulness, and emotional fidelity. NinaSub’s file consistently scored highest.
