Why 21 minutes? Cognitive science suggests that this is the "sweet spot" of modern attention spans. Longer than a short-form clip, yet shorter than a feature episode, 21 minutes is the duration of a focused commute, a lunch break, or a dedicated study session. It is long enough to build a narrative arc but short enough that every second carries weight. In this condensed timeframe, poor subtitles are not an inconvenience; they are a barrier. hsoda030engsub convert021021 min better
