It provides a rich set of cloud-based editing APIs and Skills, including features such as adding subtitles, illustrations, picture-in-picture (PiP), AI voiceovers, filters, and more. You can integrate our editing tools into any Agent-based environment, whether it’s a manually orchestrated workflow platform (such as **Coze, Dify, or N8N**) or an autonomous planning platform (such as **OpenClaw, Claude Code, or Trae**). This enables you to meet your needs for automated and bulk video production. We have open-sourced our interface code on GitHub, making it easy for various AI models to train on and learn our interfaces. Instead of fine-tuning models yourself, you can let the AI actively learn our API (feel free to give us a star to help AI index it even faster! 🀩). Enjoy It! πŸ˜€πŸ˜€πŸ˜€ [δΈ­ζ–‡θ―΄ζ˜Ž](https://github.com/sun-guannan/VectCutAPI/blob/HEAD/README-zh.md) ### Advantages 1. **API-Powered Editing:** Access all powerfull editing features, including multi-track editing and keyframe animation, through a powerful API. 2. **Real-Time Cloud Preview:** Instantly preview your edits on a webpage without downloads, dramatically improving your workflow. 3. **Flexible Local Editing:** Export projects as drafts to import into CapCut or Jianying for further refinement. 4. **Automated Cloud Generation:** Use the API to render and generate final videos directly in the cloud. ## Demos

System Requirements - Python 3.10+ - Jianying or CapCut International version - FFmpeg ### 2\. Installation and Deployment ```bash # 1. Clone the project git clone https://github.com/sun-guannan/VectCutAPI.git cd VectCutAPI # 2. Create a virtual environment (recommended) python -m venv venv-capcut source venv-capcut/bin/activate # Linux/macOS # or venv-capcut\Scripts\activate # Windows # 3. Install dependencies pip install -r requirements.txt # HTTP API basic dependencies pip install -r requirements-mcp.txt # MCP protocol support (optional) # 4. Configuration file cp config.json.example config.json # Edit config.json as needed ``` ### 3\. Start the service ```bash python capcut_server.py # Start the HTTP API server, default port: 9001 python mcp_server.py # Start the MCP protocol service, supports stdio communication ``` ## Skill Integration Guide [SkillδΈ­ζ–‡ζ–‡ζ‘£](https://github.com/sun-guannan/VectCutAPI/blob/main/vectcut-skill/README.md) [Skill Guide](https://github.com/sun-guannan/VectCutAPI/blob/main/vectcut-skill/README_EN.md) ## MCP Integration Guide [MCP δΈ­ζ–‡ζ–‡ζ‘£](https://www.google.com/search?q=./MCP_%E6%96%87%E6%A1%A3_%E4%B8%AD%E6%96%87.md) β€’ [MCP English Guide](https://www.google.com/search?q=./MCP_Documentation_English.md) ### 1\. Client Configuration Create or update the `mcp_config.json` configuration file: ```json { "mcpServers": { "capcut-api": { "command": "python3", "args": ["mcp_server.py"], "cwd": "/path/to/VectCutAPI", "env": { "PYTHONPATH": "/path/to/VectCutAPI", "DEBUG": "0" } } } } ``` ### 2\. Connection Test ```bash # Test MCP connection python test_mcp_client.py # Expected output βœ… MCP server started successfully βœ… Got 11 available tools βœ… Draft creation test passed ``` ## Usage Examples ### 1\. API Example Add video material ```python import requests # Add background video response = requests.post("http://localhost:9001/add_video", json={ "video_url": "https://example.com/background.mp4", "start": 0, "end": 10 "volume": 0.8, "transition": "fade_in" }) print(f"Video addition result: {response.json()}") ``` Create stylized text ```python import requests # Add title text response = requests.post("http://localhost:9001/add_text", json={ "text": "Welcome to VectCutAPI", "start": 0, "end": 5, "font": "Source Han Sans",read "font_color": "#FFD700", "font_size": 48, "shadow_enabled": True, "background_color": "#000000" }) print(f"Text addition result: {response.json()}") ``` More examples can be found in the `example.py` file. ### 2\. MCP Protocol Example Complete workflow ```python # 1. Create a new project draft = mcp_client.call_tool("create_draft", { "width": 1080, "height": 1920 }) draft_id = draft["result"]["draft_id"] # 2. Add background video mcp_client.call_tool("add_video", { "video_url": "https://example.com/bg.mp4", "draft_id": draft_id, "start": 0, "end": 10, "volume": 0.6 }) # 3. Add title text mcp_client.call_tool("add_text", { "text": "AI-Driven Video Production", "draft_id": draft_id, "start": 1, "end": 6, "font_size": 56, "shadow_enabled": True, "background_color": "#1E1E1E" }) # 4. Add keyframe animation mcp_client.call_tool("add_video_keyframe", { "draft_id": draft_id, "track_name": "main", "property_types": ["scale_x", "scale_y", "alpha"], "times": [0, 2, 4], "values": ["1.0", "1.2", "0.8"] }) # 5. Save the project result = mcp_client.call_tool("save_draft", { "draft_id": draft_id }) print(f"Project saved: {result['result']['draft_url']}") ``` Advanced text effects ```python # Multi-style colored text mcp_client.call_tool("add_text", { "text": "Colored text effect demonstration", "draft_id": draft_id, "start": 2, "end": 8, "font_size": 42, "shadow_enabled": True, "shadow_color": "#FFFFFF", "background_alpha": 0.8, "background_round_radius": 20, "text_styles": [ {"start": 0, "end": 2, "font_color": "#FF6B6B"}, {"start": 2, "end": 4, "font_color": "#4ECDC4"}, {"start": 4, "end": 6, "font_color": "#45B7D1"} ] }) ``` ### 3\. Downloading Drafts Calling `save_draft` will generate a folder starting with `dfd_` in the current directory of `capcut_server.py`. Copy this to the CapCut/Jianying drafts directory to see the generated draft in the application. Draft output is selected by `draft_profile` in `config.json`: - `capcut_legacy`: existing CapCut template. - `jianying_legacy`: existing Jianying template. - `jianying_pro_10`: Jianying Pro 10.x Windows-style folder layout using `draft_content.json`. ## Pattern You can find a lot of pattern in the `pattern` directory. ## Community & Support We welcome contributions of all forms\! Our iteration rules are: - No direct PRs to main - PRs can be submitted to the dev branch - Merges from dev to main and releases will happen every Monday ## Contact Us ### 🀝 Collaboration - **Video Production**: Want to use this API for batch production of videos with AIGC? - **Join us**: Our goal is to provide a stable and reliable video editing tool that integrates well with AI-generated images, videos, and audio. If you are interested, submit a PR and I'll see it. For more in-depth involvement, the code for the MCP Editing Agent, web-based editing client, and cloud rendering modules has not been open-sourced yet. **Contact**: abelchrisnic@gmail.com ## πŸ“ˆ Star History
