Questions

Here is what is worth knowing before spending an evening in it.

What it is

cutvid is a video editor that runs in a browser tab, with an MP4 at the end. It has a real timeline: ripple trim, nested sequences, keyframes, transitions, titles, an audio chain, transcription and captions. It is free, there is no account, and the footage stays on the machine.

The cutvid editor: a bin of clips, the program monitor on a forest scene, and a timeline with four clips, a title and a music track

What it does not do

  • Export is H.264 in MP4, MOV or MKV, VP9 in WebM, or the audio alone as M4A, Opus or WAV. No ProRes, no DNxHD, no H.265 out, no image sequences.
  • No team features: no cloud project, no review link, no comments, no shared library. A project lives in one browser and moves as a file.
  • No stock library and nothing generative: no stock clips, no music bed, no AI b-roll, no generative fill.
  • No third-party plugins: no OpenFX, no VST, no motion-graphics templates from another app.
  • Color is LUTs and the effect rail, not scopes, curves and secondaries. A .cube grades a clip; there is no vectorscope to grade against.
  • It runs in Chrome, Edge and the other Chromium browsers, and in Firefox, where it draws with WebGL2. Safari is not checked yet.
  • It runs in a tab, on one machine. A long 4K timeline is heavier here than in a native application on the same computer.

Questions

Is cutvid free?
Yes. There is no account, trial, paid tier or watermark. It runs on the machine that opens it.
Does it upload my video?
No. After the page loads there is no server behind it. The media, the render and the transcription all happen in the tab.
Do I need to install anything?
No. It is a web page. It can be installed as an app afterward, which is what makes it work offline.
Which browsers does it need?
A browser with WebCodecs: Chrome, Edge and the other Chromium browsers, or Firefox, where it draws with WebGL2. Safari is not checked yet.
What does it export?
H.264 in an MP4, MOV or MKV, or VP9 in a WebM, at a size and rate of your choosing, or the audio alone as M4A, Opus or WAV. Captions come out as .srt and .vtt beside it.
Can it open a Premiere, Final Cut or Resolve project?
No. Project files from other editors are not read.
What formats can it import?
It imports what the browser can decode, plus H.265 / HEVC, which is decoded by FFmpeg compiled to WebAssembly and kept as H.264, so a driver that chokes on it never sees it.
Where are my projects kept, and can I lose them?
They are kept in this browser’s storage on this machine. Clearing the browser’s data for the site deletes them, so back up anything that matters as a .cutvid file. It holds the document and every original it uses.
Is there a file size or length limit?
There is no limit set by a plan. The machine and the browser’s storage quota are the limits.
Can a script or an agent drive it?
Yes. window.editorAgent exposes every command the interface uses, documented at /AGENTS.md.
