JianYing Bridge

安全地把一个紧凑的 JSON 剪辑计划编译成可继续编辑的剪映专业版草稿。

A local Codex plugin and MCP server that compiles one compact JSON edit plan into a new, editable JianYing Pro draft.

非剪映官方项目。当前实机验证环境:macOS + 剪映专业版 11.4.2。

为什么做它

很多剪映自动化项目仍输出旧版 draft_content.json,或直接修改用户已有工程。JianYing Bridge 选择了更保守的边界:

  • 只创建新草稿,不覆盖、删除或修补现有草稿;

  • 先在沙盒生成并校验,再显式发布到剪映草稿库;

  • 视频、音频会复制进草稿自身,降低 macOS 权限和源文件移动导致的丢失风险;

  • 一次提交完整 manifest,避免“一个片段一次工具调用”的高频往返;

  • 全程使用本地素材和本机工具,本身不消耗图片/视频生成额度。

已验证能力

  • 剪映专业版 11.4.2(macOS)可发现并打开生成的草稿;

  • 视频、BGM、中文字幕可正常进入时间线并播放;

  • 剪映打开后会将草稿迁移为原生 Timelines/project.json 布局;

  • 同名工程会被拒绝,绝不静默覆盖;

  • MCP stdio 初始化、工具发现和调用通过;

  • 5 项本地回归测试通过。

MCP 工具

用途

jianying_doctor

检查剪映、草稿目录、FFmpeg 和安全边界

jianying_build_project

在沙盒目录新建可编辑草稿

jianying_validate_project

检查项目身份、时间线和本地素材引用

jianying_publish_project

将已校验的新草稿复制到剪映项目库

快速开始

依赖:macOS、剪映专业版 11.4.x、Python 3.11+、uv、FFmpeg/FFprobe。

git clone https://github.com/DeathKnight88/jianying-bridge.git
cd jianying-bridge
./scripts/launch_jianying_bridge

若作为 Codex 插件使用,可把仓库目录注册为本地插件源;.mcp.json 已配置好 stdio 服务入口。新安装的插件需要在新的 Codex 任务中加载。

Manifest 示例

{
  "version": 1,
  "project": {
    "name": "My_New_Project",
    "width": 1920,
    "height": 1080,
    "fps": 30
  },
  "video": [
    {
      "path": "/absolute/path/clip.mp4",
      "start": 0,
      "source_start": 0,
      "duration": 3,
      "track": "VideoTrack",
      "transition": {"name": "叠化", "duration": 0.3}
    }
  ],
  "audio": [
    {
      "path": "/absolute/path/music.mp3",
      "start": 0,
      "duration": 3,
      "track": "BGM",
      "volume": 0.2
    }
  ],
  "text": [
    {
      "content": "字幕",
      "start": 0,
      "duration": 3,
      "track": "Subtitles"
    }
  ]
}

时间单位统一为秒。相对素材路径以 manifest 所在目录为基准。完整模板见 assets/example-manifest.json。

推荐工作流

本地素材
  → FFprobe / Whisper / BaoCut / auto-editor(可选)
  → 一份 edit manifest
  → JianYing Bridge 沙盒生成 + 校验
  → 发布到剪映
  → 人工预览与导出

桥接器只负责执行已经确定的剪辑计划。转写、脚本判断、镜头选择等工作建议在生成 manifest 前一次性完成。

当前限制

  • v0.1 仅支持新建草稿,不编辑剪映 11.x 已有加密工程;

  • 发布时要求剪映主进程关闭,避免项目索引并发写入;

  • 最终预览和导出仍需在剪映中完成;

  • 当前只在 macOS 剪映专业版 11.4.2 做过端到端验证;Windows 和其他版本欢迎测试反馈;

  • 剪映内部格式属于非公开实现,版本升级可能导致兼容性变化。

    A3.5/5.0

    Scored across 4 tools

    Disambiguation5/5

    Each tool targets a distinct stage: environment check, build, validate, and publish. No overlap in purpose or output.

    Naming Consistency5/5

    All names use the consistent prefix jianying_ followed by a clear action (doctor, build, validate, publish). Style is uniform and predictable.

    Tool Count5/5

    Four tools form a tight, well-scoped lifecycle for the server's purpose: checking prerequisites, building, validating, and publishing drafts. No redundancy or bloat.

    Completeness5/5

    The domain is a build-and-publish bridge for JianYing drafts. The four tools cover the full pipeline from environment check to final publication, with no obvious missing operations.

      Enables MCP clients to build CapCut video draft projects on disk — adding video and image clips, audio with fades, text overlays, SRT subtitles, filters, transitions, animations and keyframes, then saving the draft for editing and opening in CapCut. It also lists existing drafts, browses available effects and fonts, and summarizes track, duration and segment details.
