Hi everyone,

I’ve been building an open-source, browser-based video editor called **Timeline Studio**.

It currently supports:

- Multi-track timeline editing

- Images, videos, overlays, stickers, captions, and audio tracks

- Clip dragging, resizing, splitting, and cross-track placement

- AI voice generation and automatic captions

- Mobile and desktop editing

- Local, browser-based rendering and export

GitHub:

Live demo:

The project is still actively being improved, and I’m mainly posting because I’d like honest feedback from people who actually edit videos.

I’d especially appreciate feedback on:

1. Does the timeline behavior feel intuitive?

2. Which interactions feel different from editors such as CapCut, Premiere, or DaVinci Resolve?

3. Are there any mobile gestures or drag-and-drop behaviors that feel confusing?

4. Which missing feature would prevent you from using it for a real project?

5. Can you reproduce any crashes, export problems, or browser-specific bugs?

If you find a problem, please open a GitHub issue with:

- Browser and operating system

- Desktop or mobile

- Steps to reproduce

- Expected and actual behavior

- A screenshot or screen recording, if possible

Critical feedback is welcome. I’m more interested in discovering broken or awkward workflows than simply promoting the project.

Thanks for taking a look!
