README
sum-the-yt
把 YouTube 影片濃縮成**繁體中文(台灣用語)**摘要的 Python pipeline。 字幕優先、Whisper 備援、用本機 `claude` CLI 摘要(**不需 API key**)。
流程
- 抓字幕:用
yt-dlp取得字幕。優先人工字幕;無人工字幕時抓原始語言的自動字幕軌(*-orig),因為 YouTube 對「機器翻譯字幕軌」會嚴重限流(HTTP 429),原始 ASR 軌則穩定,翻譯交給後面的claude。 - Whisper 備援:若完全沒有可用字幕,下載音訊並用
faster-whisper(CPU / int8)轉錄(可用--no-whisper關閉)。 - 摘要:把逐字稿丟給
claude -p輸出繁中摘要;逐字稿過長時自動 map-reduce(分段摘要再彙整)。
產出
產物依**上傳日期**分層,再以標題 slug 命名:
videos///
├── subtitle.srt # 帶時間軸的字幕(原始語言;Whisper 路徑則為轉錄結果)
├── transcript.txt # 純逐字稿
└── summary.md # 繁體中文摘要 + metadata(頻道/時長/上傳日期/ID)
取不到上傳日期時會落在 `videos/unknown-date/`。

cp .env.example .env # 設定(建議填 SUMYT_COOKIES_FROM_BROWSER=chrome)
# 單部
uv run sum-yt "https://www.youtube.com/watch?v=VIDEO_ID"
# 多部(一次給多個 URL)
uv run sum-yt URL1 URL2 URL3
# 從檔案讀清單(每行一個 URL,# 開頭為註解)
uv run sum-yt -f urls.txt
# 強制重跑(預設會跳過已存在的 summary.md)
uv run sum-yt URL --force

已知行為
- YouTube 對翻譯字幕軌限流很兇(常 429);本工具改抓原始語言軌並讓
claude翻成繁中,既穩定又更準確。 - 帶
--cookies-from-browser通常能避開大多數限流。 - 完全無字幕的影片才會走 Whisper(較慢、首次需下載模型);用
--no-whisper可讓這類影片直接失敗。
