此技能專為自動化從教學影片中提取章節索引而設計。它結合 FFmpeg 進行音訊提取，OpenAI Whisper 進行語音辨識與逐字時間戳記生成，並利用模糊字串比對將辨識出的文字與預定義的章節標題進行語義對齊。這對於需要將長篇教學影片結構化、建立可跳轉目錄或標記關鍵教學點的開發者、教育者與內容創作者尤為有用。它支援 Claude Code 等 AI 代理平台，可無縫整合到影片處理工作流程中。其運作原理是：先從影片中抽取音軌，透過 Whisper 語音轉文字模型獲得帶有時間戳記的文字，再與章節清單進行比對，最終輸出結構化的章節時間索引。

This repo contains 3 individual skills — each has its own dedicated page.
Handles audio resampling, loudness normalization per ITU-R BS.1770-4, and LUFS measurement for TTS segments to ensure broadcast-quality output.
Muxes normalized TTS audio segments into the original video at precise time offsets using FFmpeg, and generates the JSON report with timing, drift, and loudness metadata.
Synthesizes target-language speech from text using Kokoro TTS, with speed/duration control to fit precise time windows. Handles SRT parsing, text extraction, and produces WAV segments.
Extract frames or short clips from videos using ffmpeg.
Summarize or transcribe URLs, YouTube/videos, podcasts, articles, transcripts, PDFs, and local files.
Use when testing, fixing, or extending the OpenClaw Control UI GUI with Vitest + Playwright end-to-end checks, mocked Gateway WebSocket flows, mocked dashboard runs, screenshots/videos, or agent-verifiable browser proof.
