Jianying Headless: AI Video Editing Agent Skill for macOS
A local automation tool for Jianying Pro on macOS that generates editable multi-track video drafts from a structured JSON plan and exports MP4 via the native engine — with a built-in Agent Skill.
Jianying Headless is a local automation tool for Jianying Pro on macOS (Jianying is the desktop version of CapCut, used widely in China and internationally). You give it a JSON editing plan — video segments, multi-track layout, speed, volume, picture-in-picture, subtitles and titles — and it builds an editable Jianying draft in an isolated copy of your project. The native Jianying engine renders the final MP4. It also includes an Agent Skill that lets an AI agent call the editing process as a tool from within its own workflow. The project is not an official Jianying SDK and is an independent preview release. Verified on Jianying Pro 11.5.0 on macOS 26.5.1 with Apple Silicon.
Why a vibe-coder should care
If you produce video content with an AI agent and currently do the final editing assembly by hand, this bridges that gap. The Agent Skill means your agent can hand off a complete editing plan and get back a ready project. Saves the manual step of importing clips, placing them on tracks, and setting subtitles.
How to install
Copy this and send it to your agent — Claude Code, Codex, any of them:
Look at Jianying Headless: https://github.com/mcncarl/jianying-headless — a tool for automatically building Jianying Pro video projects. Install it on my Mac following the README, run the doctor check, and assemble a test project from examples/basic.plan.json; tell me if you need paths to local files.
macOS 26 with Apple Silicon only. Jianying Pro 11.5.0 must be installed. Does not run on Windows.
