+description: YouTube SBV subtitle correction and metadata generation for Jamie Clinic
+---
+
+# Jamie YouTube Subtitle Checker
+
+SBV subtitle file typo correction and YouTube metadata generation.
+
+## Triggers
+- "check subtitles", "subtitle QA"
+- "자막 교정", "SBV 파일"
+
+## Quick Commands
+
+```bash
+# SBV typo correction
+python scripts/sbv_corrector.py --input "subtitle.sbv" --output "subtitle_corrected.sbv"
+
+# Chapter extraction
+python scripts/chapter_extractor.py --input "subtitle.sbv"
+
+# Full workflow (correction + chapters + metadata)
+python scripts/process_subtitle.py --input "subtitle.sbv" --output-dir "./output"
+```
+
+## Workflow
+1. SBV parsing and text extraction
+2. Typo auto-correction (typo_dictionary.json)
+3. Medical terminology standardization
+4. Chapter timestamp extraction
+5. YouTube metadata generation
+
+## Key Typo Patterns
+
+| Category | Wrong | Correct |
+|----------|-------|---------|
+| Brand | 데이미, 재이미 | 제이미 |
+| Procedure | 쌍거풀, 쌍커풀 | 쌍꺼풀 |
+| Medical | 절계, 절게 | 절개 |
+
+## Output Files
+- `{filename}_corrected.sbv` -- Corrected subtitles
+- `youtube_video_info.md` -- YouTube metadata (title, chapters, description, hashtags)
+- `correction_report.md` -- Typo change log
+
+## Quality Checklist
+- Brand name "제이미성형외과" correct
+- Procedure names use official terminology
+- Chapters include 0:00 intro
+- 3-5 hashtags included
