A friend runs a Douyin multi-account matrix.
CapCut membership costs 30 RMB per month, 4 accounts = 120 RMB.
I thought: Do you really need paid software to edit videos? Can video editors be open source?
It’s 2026 now.
Video editors are open source, and can span Web/Desktop/Mobile with a single codebase.
OpenCut is being rewritten from scratch with a Rust core.
Currently available: http://opencut.app runs the old version (full-featured, old UI).
The new version will be moved to http://new.opencut.app after the rewrite.
The new version preview highlights 6 major capabilities:
One codebase across three platforms (Rust core)
Web/Desktop/Mobile compiled from the same code. Mobile is not a webview wrapper; desktop can leverage GPU acceleration.
Traditional open source video editors mostly support only desktop.
Plugin architecture as a first-class citizen
Third parties can integrate video filters, subtitles, transitions, and export formats. The Editor API allows programmatic access.
Plugins in traditional open source editors are just “add-on features.”
MCP server
AI agents can call it directly, e.g., “Help me batch add intros to these 100 clips.”
It’s not about adding an “AI feature” button to the video editor; it’s about exposing the editor itself to AI agents.
Headless mode
Command-line batch rendering. No GUI required; can run video processing in CI/CD.
Traditional video editors require opening the GUI.
Editor API
Third-party programmatic access.
In-editor script tag
Write JS scripts to directly drive the editor.

@0xluffy_eth: Someone created a free video editing tool for Claude Code... Insane. Just put raw footage and assets in a folder. That's it. It handles everything: - Clip segments - Remove filler words - Add subtitles - Apply color grading and filters - Handle animations - Render final video No timeline. No manual edits. No back-and-forth. Honestly, this surpasses tools like Remotion. It doesn't just help you make videos... it does the editing for you.
