Barrier-Free Subtitle Studio

Derivation Chain

Step 1 Expansion of barrier-free film screenings
→
Step 2 Barrier-free content production Infrastructure
→
Step 3 Subtitle & audio description specialized production SaaS

Problem

As barrier-free film screenings expand nationwide, demand for audio descriptions, Korean subtitles, and sign language insertion is surging. However, small film festivals and municipal cultural foundations pay 2-5 million KRW (~$1,500-$3,750) per title to specialized production houses, with turnaround times of 2-4 weeks. Over 40% of annual screening budgets go to barrier-free post-production, creating a bottleneck that limits the number of films shown.

Solution

The platform provides AI speech-recognition-based automatic subtitle drafts, audio description script templates, and sign language video insertion with timecode synchronization—all in a single web editor. A professional reviewer Marketplace is integrated to ensure quality while reducing costs by 60%.

Target: Municipal cultural foundation staff, independent film festival teams (annual budget $75,000-$375,000), NGOs focused on media accessibility for people with disabilities
Revenue Model: SaaS Monthly Subscription at 99,000 KRW (~$74)/account (includes 5 titles/month), additional titles at 39,000 KRW (~$29) each. Reviewer Marketplace transaction fee of 15%.
Ecosystem Role: Supplier
