中文影片逐字稿 — 沒字幕也能抓逐字稿
Get the transcript even when the video has no captions. 以中文為核心,也支援其他語言 / Chinese-first, works for any language.
Other transcript scrapers fail on most Chinese videos, because most Chinese videos simply have no captions to scrape. We measured it: only ~25–37% of Chinese YouTube videos have any caption track, and auto-captions are almost never generated for Chinese. This Actor scrapes the captions when they exist — and transcribes the audio with AI when they don't.
你會拿到什麼 / What you get
- 📝 完整逐字稿 — 有字幕就抓字幕(1–3 秒/支),沒有就 AI 轉錄。Full transcript either way.
- 🇹🇼 中文優先 — 繁中 → 簡中 → 通用中文 → 英文,依序挑選最合適的字幕軌。Traditional Chinese first, configurable.
- ✅ 品質過濾 — 每筆結果都經過內容檢查:太短、錯誤頁、抓錯語言軌,一律標為失敗而非混入有效資料。Quality-gated: bad results are reported as failures, never silently returned.

字幕優先取 json3 結構化格式(最穩),退回 vtt/srt 並自動清掉時間軸標記。失敗依狀態碼分流重試(404 立即放棄、429 拉長等待、403/5xx 退避重試),錯誤分為 proxy/rate-limit/blocked/network/other 五類統計於執行報告。建議開啟代理:YouTube 會擋機房 IP。
