OpenCut Browser Video Editor

OpenCut (https://opencut.app/) is an open-source, cross-platform video editor designed to be a free alternative to CapCut (the international version of 剪映). The project was started by a group of developers dissatisfied with CapCut's charging policies and promises a watermark-free, no-subscription, locally processed, completely free video editing experience.

核心特点

隐私优先：所有视频编辑操作均在用户设备本地完成，视频数据不会上传到云端，确保用户隐私安全。

完全免费：OpenCut不收取任何费用，没有"高级版"或"会员功能"，所有功能一律开放，无需登录和订阅。

开源可自托管：采用MIT许可证，任何人都可以fork、修改和部署自己的实例，支持私有部署或集成到自己的平台中。

跨平台支持：基于Web技术构建，支持Windows、macOS和Linux系统，打开浏览器即可使用。

主要功能

• Real-time preview — edit what you see

• Supports cutting, splitting, merging, and speed adjustments

• Supports importing and exporting common formats such as MP4, MOV, AVI, MKV

AI增强功能（部分功能仍在开发中）： • Multilingual video translation: supports translation between 100+ languages, automatically generates multilingual subtitles and AI voiceovers

发展现状

As of March 2026, OpenCut has over 46.7k stars on GitHub, 92 contributors, and an active community. The project is currently in Beta: core features like the timeline editor, multitrack support, and real-time preview are mostly complete, but advanced effects, a keyframe system, and complex filters are still under development.

The project is sponsored by companies such as Vercel and fal.ai, and is fully open-source, allowing users to freely modify and redistribute it. For users who prioritize privacy and want full control over their creative tools, OpenCut offers an appealing free option.
