Step 4 Multilingual subtitle auto-synchronization

Problem

University and regional opera companies—like Keimyung University's Turandot production—need Korean subtitles for Italian and German performances, but professional subtitle production costs $1,500–$3,000 (200–400만원) per show and takes 2–3 weeks. Small companies either perform without subtitles due to budget constraints or have staff manually create them, consuming over 100 hours. Frequent cue timing mistakes during live performances also break audience immersion.

Solution

Upload an opera libretto and AI automatically generates Korean and English subtitles with cue timing synchronized to the musical score. Provides real-time fine-tuning during rehearsals and one-click cue execution on performance day.

Target: University opera departments (~20 nationwide), regional opera companies and choirs, performance production companies (annual revenue $750K–$7.5M)
Revenue Model: Per Transaction $150/show (199,000원) (under 120 min), Annual Subscription $1,120 (1,490,000원) (unlimited), 40% university discount
Ecosystem Role: Education
MVP Estimate: 2_weeks
