YouTube Transcript Downloader

유튜브 영상에서 자막을 추출하고 처리하는 스킬입니다.

Priority Order

1. yt-dlp 설치 확인
2. 사용 가능한 자막 목록 확인
3. 수동 자막 우선 시도
4. 자동 생성 자막 폴백
5. 최후 수단: Whisper 변환

Requirements

# macOS
brew install yt-dlp

# Linux
sudo apt install yt-dlp

# Universal
pip install yt-dlp

Workflow

Step 1: 자막 목록 확인

yt-dlp --list-subs "VIDEO_URL"

Step 2: 수동 자막 다운로드 (권장)

# 한국어 자막
yt-dlp --write-sub --sub-lang ko --skip-download "VIDEO_URL"

# 영어 자막
yt-dlp --write-sub --sub-lang en --skip-download "VIDEO_URL"

Step 3: 자동 생성 자막 (폴백)

yt-dlp --write-auto-sub --sub-lang ko --skip-download "VIDEO_URL"

Step 4: VTT → 텍스트 변환

# VTT 파일에서 타임스탬프 제거
sed '/^[0-9]/d; /^$/d; /-->/d' subtitle.ko.vtt > transcript.txt

Output Processing

중복 제거

자동 생성 자막은 progressive 캡션으로 인해 중복이 많음:

# 중복 라인 제거
seen = set()
unique_lines = []
for line in lines:
    if line not in seen:
        seen.add(line)
        unique_lines.append(line)

요약 생성

추출된 자막으로:

  • 핵심 내용 요약
  • 타임스탬프별 챕터 생성
  • 주요 키워드 추출

Examples

Example 1: 강의 영상 요약

User: 이 유튜브 강의 요약해줘 - https://youtube.com/watch?v=xxx

Claude:
1. yt-dlp로 자막 다운로드
2. VTT → 텍스트 변환
3. 핵심 내용 요약 생성
4. 타임스탬프별 목차 제공

Example 2: 다국어 자막 추출

User: 이 영상의 영어/한국어 자막 둘 다 추출해줘

Claude:
1. --list-subs로 가용 언어 확인
2. 각 언어별 자막 다운로드
3. 정리된 텍스트 파일 제공

Error Handling

에러원인해결책
yt-dlp not found미설치brew/apt/pip 설치
No subtitles available자막 없음Whisper 사용 제안
Invalid URLURL 오류URL 형식 확인
Video unavailable비공개/삭제사용자에게 알림

Whisper Fallback

자막이 전혀 없는 경우 (사용자 확인 필요):

# 파일 크기 확인
yt-dlp --print filesize "VIDEO_URL"

# 사용자 승인 후 오디오 다운로드
yt-dlp -x --audio-format mp3 "VIDEO_URL"

# Whisper로 변환
whisper audio.mp3 --language ko --model base

주의: 대역폭/처리 시간 소요로 사용자 확인 필수
