rea-video（GitHub：https://github.com/JuneYaooo/rea-video ，2026-10-29 创建，今晨抓取时已 4,491★）能逆向任何视频：逐个镜头判断它是实拍的、AI 生成的还是代码做出来的，再告诉你怎么复刻。

README 里举的例子很直观：左边是一条手机实拍的 TikTok 广告，右边是别人用 AI 翻拍的同款、换了个产品；rea-video 的结论是：左边全是实拍，一个场景、两个机位；右边全是 AI，8 个镜头、跨 3 次生成。它是为 AI Agent 而生的：在 Claude Code、Codex 或任何能跑命令的 Agent 里说一句“安装这个仓库，然后拆解这段视频”，Agent 就会装好 CLI、学好工作流、把整件事跑完。需要 ffmpeg 与 Python 3.10 以上，官网是 reavideo.ai，README 提供中、英、俄、日、韩、西、葡、法、德九种语言。

按 README 的说法，它不只给结论，还给复刻方法：每个镜头怎么拍、用什么生成、参数大概是什么，都拆给你看。对做短视频、广告、AI 视频的人来说，这等于把“别人这条爆款视频到底怎么做出来的”这个黑盒打开了。

为什么值得了解

• 视频已经是 AI 生成的重灾区：会看一条视频是实拍还是 AI 做的、再反推出制作方法，是做内容的人越来越需要的硬技能
• 它是典型的“给 Agent 用的工具”：不是让你自己点点点，而是让 Claude Code / Codex 替你把活干完，顺应了 Agent 时代工具的写法
• 中文作者，README 直接给了中文版；和之前推过的“逆向一切程序”的 REA 是同一条思路，只是战场从代码换成了视频

English Version

rea-video (GitHub: https://github.com/JuneYaooo/rea-video , created 2026-10-29, 4,491 stars at this morning’s fetch) reverse-engineers any video: shot by shot, it tells you whether it was filmed, AI-generated or coded — and how to remake it.

The README’s example makes it concrete: on the left, a TikTok ad shot on a phone; on the right, someone’s AI remake of the same ad with a different product. rea-video’s verdict: the left is all live footage, one set and two camera positions; the right is all AI, 8 shots across 3 generations. It is built for AI agents: in Claude Code, Codex or any agent that can run commands, say “install this repo, then break down this video” and the agent installs the CLI, learns the workflow and runs the whole thing. You need ffmpeg and Python 3.10 or newer; the website is reavideo.ai, and the README comes in nine languages including Chinese, English, Russian, Japanese and Korean.

Per the README, it doesn’t stop at a verdict — it also gives you the recipe: how each shot was filmed, what generated it, and roughly which parameters, all broken down for you. For anyone making short videos, ads or AI video, that opens up the black box of “how exactly was this viral video made”.

Why it’s worth knowing

• Video is now prime territory for AI generation: being able to tell whether a clip was filmed or AI-made — and reverse-engineer how it was produced — is becoming a hard skill for anyone making content
• It is a textbook “tool built for agents”: instead of clicking through it yourself, you let Claude Code or Codex do the work, which is how tools are increasingly written in the agent era
• A Chinese author with a Chinese README; it follows the same idea as the previously featured REA (“reverse engineer anything”), only the battlefield moves from code to video
