什么是 ChatCut Codex 插件
chatcut.io/codex 是 ChatCut 专门为 OpenAI Codex Agent 写的插件安装指引页面。
安装后,Codex Agent 可以通过 MCP(Model Context Protocol)工具调用 ChatCut 的全部编辑 API——这意味着你可以用对话的方式驱动专业级视频编辑器。
Agent 能做的事(通过插件):
- 导入本地或网络视频素材
- 读取/修改项目时间轴
- 生成并放置动态图形(Motion Graphics)
- 转录音频、添加字幕
- 生成 AI 配音并与画面同步
- 生成 AI 视频 / 图片素材并插入时间轴
- 导出成品视频,返回下载链接
这不是”帮你写剪辑脚本”——Agent 真正地在操作 ChatCut 项目,改动在编辑器里实时可见。

入门:如何接入 Codex
前置条件
- 已安装 Codex 桌面应用(OpenAI Codex Desktop App)
- 系统已安装
ffmpeg(ChatCut 媒体导入依赖) - ChatCut 账号(免费注册)
验证 ffmpeg:
ffmpeg -version
第一步:安装 ChatCut 插件
在 Codex 里打开一个对话,输入:
Turn Codex into a video editor, read chatcut.io/codex
Codex Agent 会读取安装指引并自动执行:添加插件 marketplace、安装 ChatCut 插件、发起 OAuth 登录。
或者手动执行(把 <bundled-codex> 替换为你的 Codex 内置 CLI 路径):
# 添加 ChatCut 插件 marketplace
<bundled-codex> plugin marketplace add https://github.com/ChatCut-Inc/agent-plugin.git --ref main
# 查看 marketplace 名称
<bundled-codex> plugin marketplace list
# 安装插件
<bundled-codex> plugin add chatcut@<marketplace-name>
# 登录 ChatCut
<bundled-codex> mcp login chatcut
第二步:验证安装
<bundled-codex> plugin list --marketplace <marketplace-name>
<bundled-codex> mcp get chatcut
ChatCut 一行显示 installed, enabled 即为成功。
第三步:开始剪辑
在 Codex 新对话里,直接用自然语言:
Import this video into my ChatCut project.
(把这个视频导入我的 ChatCut 项目)
Add a simple motion graphic overlay.
(添加一个简单的动效叠加层)
Generate a voiceover and background music.
(生成配音和背景音乐)
Transcribe this clip and add captions.
(转录这个片段并加字幕)
Export the current project.
(导出当前项目)
几个实际场景
场景一:口播视频快速清理
Clean up all the filler words in this talking head video,
add captions in TikTok Pop style.
(清理这个口播视频里的所有口癖词,加 TikTok Pop 风格字幕)
Agent 会:转录音频 → 识别 “um”/“uh”/“you know” 等 → 在时间轴上切掉对应片段 → 生成字幕并套用样式。
场景二:生成章节动效
Turn this rough creator edit into crisp chapters, charts,
and emphasized on-screen moments.
(把这段粗剪变成有清晰章节卡片、图表和重点强调的成品)
Agent 分析视频内容,生成章节卡片动效、数据图表动效,并放置在合适时间点。
场景三:补拍不到的 B-roll
Generate a cinematic shot of a busy Tokyo street at night
for the 0:30 mark.
(在 0:30 处生成一个东京夜晚街道的电影感镜头)
Agent 调用 Seedance 2.0 生成视频,直接插入时间轴指定位置。
场景四:AI 配音 + 同步
Generate a professional English voiceover for this product demo,
sync it with the on-screen content.
(为这个产品演示视频生成专业英文配音,与画面内容同步)
Agent 分析画面内容 → 生成旁白文本 → TTS 转为语音 → 按画面节奏对齐放置。

和其他 AI 视频工具的区别
| ChatCut | CapCut AI | RunwayML | Descript | |
|---|---|---|---|---|
| Agent 驱动编辑 | ✅ (Codex 插件) | ❌ | ❌ | ❌ |
| 文字剪辑 | ✅ | ⚠️ 有限 | ❌ | ✅ |
| AI 动态图形 | ✅ JSX 级别 | ⚠️ 模板 | ❌ | ❌ |
| AI 视频生成 | ✅ Seedance/Kling | ✅ | ✅ | ❌ |
| AI 音乐生成 | ✅ | ✅ | ❌ | ❌ |
| 浏览器内编辑 | ✅ | ✅ | ✅ | ✅ |
| MCP 工具集成 | ✅ | ❌ | ❌ | ❌ |
ChatCut 的核心差异点在于 Agent 可编程性——通过 MCP 协议,任何支持工具调用的 AI Agent 都可以驱动 ChatCut 做视频编辑,而不只是在 UI 里点来点去。
一句话总结
ChatCut 把视频编辑变成了一个可以被 Agent 调用的服务。你写提示词,Agent 在专业视频编辑器里真正地执行操作。
对于内容创作者:这是目前入门门槛最低的全功能 AI 视频编辑工具之一。 对于开发者/Agent 爱好者:这是第一个把视频编辑全流程暴露成 MCP 工具集的产品。

ChatCut × Codex: Edit Video with an AI Agent — Your Prompt Is the Timeline
If you use Codex (OpenAI’s agent tool), it can now edit video for you.
ChatCut has released an official Codex plugin that connects the entire video editing workflow to the Agent runtime. Type a prompt in Codex, and the Agent executes in your ChatCut project — trimming footage, adding captions, generating motion graphics, creating AI voiceovers, generating B-roll, and exporting the final cut.
Product: chatcut.io · Plugin install: chatcut.io/codex
What ChatCut Is
ChatCut is a browser-based AI video editor. Its pitch: tell it what you want, and it figures out how to do it.
Core capabilities:
- Text-based editing: transcript-driven editing — change a word, cut a sentence in the transcript, and the timeline follows
- AI captions: auto-generated in 100+ languages, 20+ style templates
- Motion graphics: generate chapter cards, charts, emphasis effects from a sentence — no After Effects, no keyframing
- AI image generation: generate thumbnails, B-roll reference images (GPT Image 2) inside your project
- AI video generation: generate B-roll and establishing shots you couldn’t film (Seedance 2.0 / Kling)
- AI voiceover: text-to-speech narration, synced to on-screen content
- AI music: describe the vibe, get a royalty-free track cut precisely to your video length
Free plan available, no credit card required.
What the Codex Plugin Does
chatcut.io/codex is the official install guide for the ChatCut Codex plugin. Once installed, the Codex Agent gets access to ChatCut’s full editing API via MCP (Model Context Protocol) — meaning you drive a professional video editor through conversation.
The Agent is genuinely operating ChatCut: changes appear live in the editor.
The plugin gives Codex 15 built-in skills:
| Skill | Covers |
|---|---|
chatcut-plugin-basics | Project model, data structures, operating rules |
talking-head-guide | Filler-word removal, transcript cleanup, captions |
create-motion-graphics | JSX-level direct authoring of motion graphic assets |
transcription | Audio transcription driving the text-edit workflow |
video-gen | Seedance 2.0 / Kling AI video generation |
image-gen | AI image generation with reference images |
voice | TTS voiceover, narration, video sync |
music | AI music generation matched to video duration |
export | Project export and progress tracking |
verification | Rendered screenshot confirmation of edits |
Getting Started
Prerequisites: Codex Desktop App installed, ffmpeg in PATH, ChatCut account (free).
Install in one prompt: Open a new Codex conversation and type:
Turn Codex into a video editor, read chatcut.io/codex
Codex reads the install guide and handles everything: adds the plugin marketplace, installs the plugin, opens the OAuth login flow.
Then start editing with natural language:
Import this video into my ChatCut project.
Add a simple motion graphic overlay.
Generate a voiceover and background music.
Transcribe this clip and add captions.
Export the current project.
Real Scenarios
Talking-head cleanup: “Clean up all the filler words and add TikTok Pop captions.” → Agent transcribes, identifies um/uh/you know, cuts them from the timeline, applies caption style.
Motion graphics: “Turn this rough edit into crisp chapters and charts.” → Agent generates chapter card and chart motion graphics at the right timestamps.
Missing B-roll: “Generate a cinematic Tokyo night street shot for the 0:30 mark.” → Agent calls Seedance 2.0, inserts generated clip at 0:30.
AI voiceover: “Add a professional English voiceover synced to this product demo.” → Agent analyzes the screen content, writes narration, generates TTS audio, aligns it to the visual beats.
Pricing
| Plan | Price | Key limits |
|---|---|---|
| Free | Free, no card | Trial credits for captions, images, music, motion graphics |
| Plus $25/mo | $25/mo | 100 credits — up to 166s of Seedance video, 454 GPT images |
| Plus $100/mo | $100/mo | 400 credits — up to 666s video, 1818 images |
All paid plans include full AI Agent editing capabilities.
Why It’s Different
ChatCut’s real differentiator isn’t any individual feature — it’s agent programmability. By exposing the full editing workflow as MCP tools, any AI agent with tool-calling support can drive ChatCut. Not clicking through a UI — actually operating the editor through code.
For content creators: probably the lowest-barrier full-featured AI video editor available right now.
For developers and agent enthusiasts: the first product to expose a complete video editing workflow as an MCP tool surface.
