-## Why this exists
+## 为什么做这个
-HTML→Video is a real category — but every engine is opinionated, and each wants you to learn *its* authoring model:
+HTML→Video 是个真实存在的品类 —— 但每个引擎都各有主张，且都要你学*它自己*的创作模型：
-| Engine | Paradigm | Tradeoff | In html-video |
+| 引擎 | 范式 | 取舍 | 在 html-video 中 |
|---|---|---|---|
-| [Hyperframes](https://github.com/heygen-com/hyperframes) | HTML + CSS + GSAP, agent-skill driven | Single rendering paradigm | ✅ **Shipped** — the default engine; renders real MP4 via headless Chromium + ffmpeg |
-| [Remotion](https://www.remotion.dev/) | React components | Source-available, paid above 4 devs | 🗺️ Planned |
-| [Motion Canvas](https://github.com/motion-canvas/motion-canvas) · [Revideo](https://github.com/redotvideo/revideo) | TypeScript generators on canvas | Best for explainers, code-first | 🗺️ Planned |
-| [Manim](https://github.com/3b1b/manim) & friends | Math / 3D first | Niche | 🗺️ Researching |
+| [Hyperframes](https://github.com/heygen-com/hyperframes) | HTML + CSS + GSAP，agent skill 驱动 | 单一渲染范式 | ✅ **已发布** —— 默认引擎；经无头 Chromium + ffmpeg 渲染出真实 MP4 |

+| [Motion Canvas](https://github.com/motion-canvas/motion-canvas) · [Revideo](https://github.com/redotvideo/revideo) | canvas 上的 TypeScript 生成器 | 最适合解说类、代码优先 | 🗺️ 计划中 |

-Picking the right engine per use case, learning each model, and stitching them into one workflow costs real engineering time. Most teams pick one and live with its limits.
+按场景挑引擎、学每一种创作模型、再把它们拼成一条工作流，都要耗真实的工程时间。多数团队挑一个、然后忍受它的局限。
-**html-video is the meta-layer that sits above all of them.** You talk to your agent; it picks the engine, picks the template, fills in your content, and renders the video. The engine is an implementation detail behind a single adapter interface — one `render(input, ctx)` contract that any backend can satisfy. Add a new engine and every template, every agent, and the whole studio workflow get it for free. No new DSL to learn, no rewrite when you switch engines.
+**html-video 是凌驾于它们之上的 meta-layer。** 你跟 agent 对话，它挑引擎、挑模板、填进你的内容、渲染视频。引擎只是一个适配器接口背后的实现细节 —— 一份 `render(input, ctx)` 契约，任何后端满足它即可接入。加一个新引擎，所有模板、所有 agent、整条 studio 工作流就都自动用上了。不用学新的 DSL，换引擎也不用重写。
-The same idea powers [Open Design](https://github.com/nexu-io/open-design) in the *design* space — an agent meta-layer over many tools. html-video is the *motion* counterpart from the same team.
+同一套思路也驱动着 [Open Design](https://github.com/nexu-io/open-design) 在*设计*领域的产品 —— 凌驾于众多工具之上的 agent meta-layer。html-video 是同一团队在*动态视频*这一面的对应物。
-> **Status:** the pluggable-engine architecture is in place, and the **Hyperframes engine is fully wired up and renders real MP4** — headless Chromium records the animated HTML frame-by-frame and ffmpeg encodes it (libx264). Remotion, Motion Canvas / Revideo, and Manim are on the roadmap: the adapter interface is designed for them, but their adapters aren't built yet. The "In html-video" column above is the single source of truth for what's actually runnable today.
+> **状态：** 可插拔引擎架构已就位，**Hyperframes 引擎已完整接通、能渲染出真实 MP4** —— 无头 Chromium 逐帧录制带动画的 HTML，再用 ffmpeg 编码（libx264）。Remotion、Motion Canvas / Revideo、Manim 在路线图上：适配器接口已为它们设计好，但适配器本身还没写。上表「在 html-video 中」这一列，是当下真正可运行内容的唯一权威来源。

-## How it works
+## 它如何工作
-One sentence (or one link) goes in; a real MP4 comes out. The pipeline is the same whether you start from a prompt, an article, or a repo:
+一句话（或一个链接）进去，一支真实 MP4 出来。不论你从一句 prompt、一篇文章还是一个仓库开始，管线都是同一条：
```
- prompt / link / repo
+ prompt / 链接 / 仓库
│
▼
- ① source fetch studio pulls the URL or repo server-side, flattens it to Markdown
+ ① 来源抓取 studio 在服务端拉取 URL 或仓库，扁平成 Markdown
│
▼
- ② agent loop your agent reads the material + the picked template's style and emits
- │ a content-graph (the storyboard) + one HTML block per frame
+ ② agent 循环 agent 读素材 + 所选模板的风格，产出一份
+ │ content-graph（故事板）+ 每帧一个 HTML 块
▼
- ③ content-graph multi-frame IR — nodes (entity / data / text) + edges (sequence /
- │ dependency / contrast); topo-sorted into frame order & timing
+ ③ content-graph 多帧中间表示 —— 节点（实体 / 数据 / 文本）+ 边（顺序 /
+ │ 依赖 / 对比）；拓扑排序成帧序与时长
▼
- ④ per-frame HTML each node becomes a self-contained animated HTML frame on disk
+ ④ 逐帧 HTML 每个节点变成一个自包含、带动画的 HTML 帧，落到磁盘
│
▼
- ⑤ Hyperframes render headless Chromium loads each frame, records it (auto-extending to
- │ cover the frame's own animation), → webm per frame
+ ⑤ Hyperframes 渲染 无头 Chromium 加载每一帧并录制（会自动延长时长
+ │ 以覆盖该帧自身的动画）→ 每帧一个 webm
▼
- ⑥ ffmpeg each webm → mp4 (libx264), then concat into one video;
- │ optional MiniMax music + narration mixed in
+ ⑥ ffmpeg 每个 webm → mp4（libx264），再 concat 成一支视频；
+ │ 可选混入 MiniMax 的音乐 + 旁白
▼
- your.mp4
+ 你的.mp4
```
-Steps ②–④ are where the "meta-layer" lives: the agent decides the storyboard and the engine decides how to draw it, and neither leaks into the other. Step ⑤ is engine-specific — swapping in Remotion or Motion Canvas later replaces only that box, leaving the storyboard and the agent loop untouched. Everything runs on your machine; the only network calls are the optional source fetch and the optional soundtrack.
+第 ②–④ 步正是「meta-layer」所在：agent 决定故事板，引擎决定怎么画，两者互不渗透。第 ⑤ 步是引擎相关的 —— 以后换成 Remotion 或 Motion Canvas，只替换这一个环节，故事板和 agent 循环原封不动。全程在你本机运行；唯二的网络调用是可选的来源抓取和可选的配乐。
-Single-frame videos take a fast path that skips the content-graph — one template, one HTML, straight to render.
+单帧视频走一条快速路径，跳过 content-graph —— 一个模板、一个 HTML，直接渲染。
---
-## Turn a link into a video
+## 把链接变成视频
-This is what most people reach for: hand your agent a link, get a video back. The agents run as local CLIs with no network access of their own, so the studio fetches the source **server-side** and feeds the real content into the generation prompt — no copy-pasting article bodies, and pages behind a login-free server render (like WeChat 公众号) just work.
+这是大多数人最想要的用法：丢一个链接给 agent，拿回一支视频。agent 作为本地 CLI 运行、自身没有联网能力，所以 studio 在**服务端**抓取来源、把真实内容喂进生成 prompt —— 不用手动复制正文，像微信公众号这种无需登录的服务端渲染页面也直接能用。
```
-You: 做一个解读视频 https://mp.weixin.qq.com/s/…
-Agent: 好，我读完了《用嘴剪视频的时代来了？…》这篇文章 — 这就基于它生成。下一步选风格。
-→ multi-frame explainer, built from the article's actual points
+你： 做一个解读视频 https://mp.weixin.qq.com/s/…
+Agent：好，我读完了《用嘴剪视频的时代来了？…》这篇文章 — 这就基于它生成。下一步选风格。
+→ 一支多帧解说视频，基于文章的真实要点
```
-- **Web article** → fetched and flattened to Markdown. Server-rendered pages like **WeChat 公众号** articles work out of the box.
-- **GitHub repo** → description, top-level structure, and README pulled via the public API — great for "explain this open-source project" videos.
-- **Just a prompt** → describe the topic and the agent writes the content from scratch.
+- **网页文章** → 抓取并扁平成 Markdown。像**微信公众号**这种服务端渲染的页面开箱即用。
+- **GitHub 仓库** → 通过公开 API 拉取简介、顶层结构、README —— 很适合做「解读某开源项目」的视频。
+- **只给一句话** → 描述主题，agent 从零写内容。
-Whatever the source, it becomes the material the video is actually built from — not decoration around a canned template. The agent reads the fetched content, decides how many scenes it needs, and writes a **content-graph storyboard**: the key points become frames, the relationships between them (this follows that, this contrasts with that) become edges, and the picked template's visual style is applied per frame. So a 1,500-word article turns into a paced multi-scene explainer whose every line traces back to something in the source, and a repo turns into a structured walkthrough of what the project actually is.
+无论哪种来源，它都会成为视频真正依据的素材 —— 不是套模板时的摆设。agent 读取抓来的内容，自己决定需要几个场景，写出一份 **content-graph 故事板**：要点变成帧，要点之间的关系（这个承接那个、这个对比那个）变成边，再把所选模板的视觉风格逐帧应用上去。于是一篇 1500 字的文章变成一支有节奏的多场景解说，每一句都能追溯回原文的某处；一个仓库变成一段「这个项目到底是什么」的结构化讲解。
