Showcasing OpenCut: A Lightweight Open-Source Video Editor Built with Python (And How You Can Help)
Hi DEV Community! 👋
I'm excited to introduce OpenCut — a simple, lightweight, and open-source video editor I'm building with Python and PyQt5. It's designed for beginners, low-end machines, and anyone who wants a no-fuss way to cut and trim videos.
🎬 OpenCut is 100% free, no watermarks, no ads — just clean, open-source code.
Why OpenCut?
Most video editors are either too heavy (like DaVinci Resolve) or too limited (like basic trimmers).
I wanted to create something in the middle:
- ✅ Lightweight (runs smoothly on older laptops)
- ✅ Cross-platform (Windows, macOS, Linux)
- ✅ Intuitive UI with standard keyboard shortcuts
- ✅ 10 beautiful themes (including dark mode and eye-comfort options)
- ✅ Thumbnail previews for media files
And yes — it's built entirely in Python. 🐍
🖼 Screenshots
Here’s what it looks like:

All 10 built-in themes — perfect for day, night, or sensitive eyes.
Current Development: Delta v1.0.0
We're in the Delta phase — active development and testing.
What's Done:
- 10 CSS-based themes
- Support for MP4, AVI, MOV, MKV, and more
- Media thumbnail previews
- Standard shortcuts (Ctrl+Z, Space, etc.)
- Extremely low resource usage
In Progress:
- 🔧 A custom timeline panel for precise editing
- ✨ Text and video effects (fade, blur, transitions)
- 🌍 Multilingual support (Arabic, French, Chinese coming in Beta v1.0.79)
- 🛠 Improving UI responsiveness
🤝 This Is a Community Project
OpenCut is not just my project — it’s by the community, for the community.
I’m actively looking for help from:
- 💻 Python/PyQt Developers – Help build the timeline, fix bugs, optimize code
- 🎨 Designers – Create new themes, icons, or improve the UI
- 🌍 Translators – Help translate the interface (Arabic, French, Chinese needed!)
- 🐞 Testers – Try the app, report bugs, suggest UX improvements
🚀 How to Try It
It’s easy to run locally:
bash
git clone https://github.com/KinanCodeaz/opencut.git
cd opencut
pip install -r resources/requirements.txt
python main.py
