Browser video editor
A browser video editor lets you cut, caption, and export video without installing software. FrameOS runs in the browser and handles the full short-form pipeline: finding clips in long recordings, reframing to vertical, captioning, and exporting without a desktop app.
Nothing to install
FrameOS loads in any modern browser. Upload a file or paste a link, and the full editing pipeline runs in the cloud — transcript generation, clip finding, reframe, and caption rendering all happen server-side so there is nothing to install, update, or troubleshoot on your machine.
What a browser editor can do for short-form
The most time-consuming parts of short-form production are finding clips in long recordings, reframing landscape footage to vertical, and placing captions. All three run in the FrameOS browser editor. You review the shortlist, adjust caption styles, and export — the heavy processing is done before you interact with a single frame.
Works on any computer
Because the editor runs in the browser and processing is cloud-based, it works on any machine that can run a browser — Mac, Windows, or Chromebook — without depending on local CPU or GPU. A laptop that would struggle through a local video export handles the review and approval stage without issue.
Editable timeline and captions
The review stage is a lightweight browser-based timeline: trim clips, adjust caption text, change styles, and reorder your shortlist. Rendering happens on export, not during editing, so the browser stays responsive even for long source videos.
