FrameCastStudio
Free browser video editor that stays on your device
FrameCast Studio is a free editor in the browser: import a take, trim and split, reframe for Reels or YouTube, and export MP4 on your own device. Media is not uploaded to finish an edit.
Use it after a Mac recording, or bring in footage from elsewhere when you need a quick cut without installing a desktop NLE.
What you can do
- Import video and work on a timeline in the browser
- Trim, split, and reframe for common aspect ratios
- Export MP4 locally — the cut finishes on your machine
- Optional voice-over later from the Mac app when you want credits-based narration
When Studio fits
Fast social crops, lesson trims, and demo polish without opening a heavy editor. For floating camera capture, screen crop, captions, and briefs, start with the Mac menu bar app — Studio is the edit pass.
Privacy posture
Editing does not require a cloud media library. Sign-in matters when you buy voice credits or manage an account — not to keep a local MP4 export.
Takeaways
- • Studio is free browser editing with local MP4 export.
- • Nothing is uploaded just to cut and export.
- • Capture still happens in the Mac app; Studio is for the edit.
