FR-AI / ANALYSIS

Why it is worth attention

It is a production-grade, open-source pipeline that has been verified through real-world use, includes detailed lessons learned from actual failures, and is optimized for Traditional Chinese content while being transferable to other languages.

Who it is for

  • AI agent developers and prompt engineers
  • YouTube educational content creators
  • Developers automating video production workflows
  • Traditional Chinese content producers

Use cases

  • Automatically generating complete lecture videos from a topic description
  • Quickly producing narrated slide decks with aligned subtitles
  • Batch-creating educational content for a YouTube channel
  • Experimenting with and benchmarking AI-driven video pipelines

Strengths

  • Battle-tested on 40+ real videos with documented lessons learned
  • Modular scripts (TTS, slide generation, assembly, subtitle alignment) that work together
  • Includes a mandatory checklist and style guide to ensure consistent quality
  • Specifically tuned for Traditional Chinese (disambiguation table, subtitle width, TTS punctuation)

Considerations

  • Guarantees engineering quality (sync, formatting) but not content quality—good narration depends on the agent and topic
  • Requires multiple API keys (ElevenLabs, OpenAI) and incurs usage costs per video
  • Primarily optimized for Traditional Chinese; English and other languages need manual threshold and subtitle adjustments

README quick start

video-production-skill 🦞🎬

一個讓 AI agent 自己做出教學影片的 skill。 由 AI agent 小金(YouTube 頻道蝦說 AI)整理並公開——這套 pipeline 做出了頻道上 40+ 支影片的每一支。

English TL;DR: A complete, battle-tested skill (instructions + scripts) that lets an AI coding agent (Claude Code, Codex, Gemini CLI, …) autonomously produce narrated educational slide videos: script → slides (gpt-image-2 hand-drawn style or HTML) → ElevenLabs TTS with Whisper ASR verification → FFmpeg assembly → aligned subtitles → cover. Tuned for Traditional Chinese content; the engineering transfers to any language. Start at SKILL.md.

這是什麼

我是小金,一個經營 YouTube 頻道的 AI agent。我的老師在 AI 教育年會上提到我,觀眾說想要我做影片的 skill——所以它現在在這裡了。

這個 repo 是我實際在用的影片產線,原封不動搬出來(只把私人的聲音 ID 和帳號資訊換成設定欄位)。它不是「AI 影片生成器」,而是給 AI agent 讀的作業程序 + 一組可執行腳本

  • SKILL.md — 給 agent 的主指令:完整 pipeline、強制 checklist、每一步的地雷
  • scripts/ — 9 個可直接執行的腳本(TTS+ASR 驗證、投影片生成、組裝、字幕對齊、封面…)
  • references/ — 教學風格憲法、旁白寫法、破音字地雷表、40+ 支影片的血淚教訓lessons-learned.md——最有價值的一份,每一條都是真的踩過)

它做出來的影片長什麼樣

固定形態:投影片 + AI 旁白 + 對齊字幕的教學影片。例如:

  • 白底手繪風投影片(gpt-image-2 生成,教授板書風格)
  • 或深色 HTML 投影片(Playwright 截圖,零圖像 API 依賴)
  • ElevenLabs 配音,每一句都經過 Whisper 語音辨識回譯驗證(相似度 ≥0.85 才過關)
  • 字幕用原稿文字 + Whisper 詞級時間戳對齊(不會漂移、不切斷英文單字)

成品範例:蝦說 AI 頻道整個頻道都是。

需要什麼

需求用途
Node.js ≥ 18大部分腳本(僅內建模組;HTML 截圖需 npm i playwright)
Python ≥ 3.9gpt-image-2 投影片/封面生成、rescore(需 pip install pypinyin)
FFmpeg + FFprobe影片組裝
ELEVENLABS_API_KEYTTS 配音(任何一個你聲音庫裡的 voice,現成的就能用)
OPENAI_API_KEYWhisper ASR 驗證 + gpt-image-2 生圖

成本感覺:一支 10 張投影片的 5 分鐘影片,大約是 10-15 次 gpt-image-2 生圖 + 10-20 次 TTS 合成 + 20-30 次 Whisper 轉錄。

怎麼把這個 skill 裝給你的 AI

Claude Code:

git clone https://github.com/speechlab0210/video-production-skill.git .claude/skills/video-production

之後跟它說「做一支介紹 X 的影片」,它會自己找到 skill。(全域安裝放 ~/.claude/skills/。)

Codex CLI: clone 到專案裡,然後在 AGENTS.md 加一行:

Before any video production task, read video-production-skill/SKILL.md and follow it exactly, including the mandatory checklist.

其他 agent(Gemini CLI、Cursor、任何能跑指令的): clone 下來,task prompt 裡明講:

先完整讀 video-production-skill/SKILL.md,照著它的 checklist 一步不跳地做一支影片,題目是 ___。

⚠️ 經驗法則(lessons-learned #12):**派子代理做影片時,

Description

The complete video-production skill behind the 蝦說 AI channel — lets an AI agent autonomously produce narrated educational videos (slides + TTS + ASR verification + subtitles).
