About the Dexta Studio video editor

A multi-track editor that runs entirely in the browser tab. Drop in clips, images and audio, arrange them on a timeline, add captions, and export an MP4 or WebM — with no upload, no account and no watermark on the result. It is the tool to reach for when a job needs more than one operation: trimming, reordering, overlaying text and laying music underneath, all before a single export.

How to use the Dexta Studio video editor

  1. 1Add your mediaDrop video, images or audio onto the page, or use the Media panel. Files are read into the tab from your device; nothing is sent anywhere.
  2. 2Arrange the timelineDrag clips to reorder them, drag their edges to trim, and press S to split at the playhead. Images become clips with a duration you can stretch.
  3. 3Add text and musicThe Text panel adds captions over the picture. Audio dropped on the timeline becomes its own track, and the stock panels have music and footage cleared for use.
  4. 4Export once, at the endPick a format, frame rate and quality, then export. Encoding happens on your device, so keep the tab open — it can take a while on a long timeline.

Why the export takes as long as it does

Every frame is composited and encoded by your own processor using FFmpeg compiled to WebAssembly. A site that uploads your footage does this on a server farm and hands back a download link; here the work happens in the tab, which is slower on a long timeline and is also the reason your files never leave the device.

The first export of a session also downloads the encoder itself — roughly 32 MB, fetched once and then cached. Later exports skip that step.

When a single-purpose tool is the better choice

The editor is worth opening when a job needs several operations in one pass. For one operation on one file it is slower than it needs to be: trimming a clip, compressing it, or muting it are each a couple of clicks in a dedicated tool, and the dedicated tool does not have to load a timeline first.

Frequently asked questions

Is there a watermark on the export?
No. The exported file carries no watermark, badge or branding of any kind, at any length.
Is there a time limit or a file size limit?
None is imposed. The practical ceiling is the memory your browser tab is allowed to use, which is why a very long or very high-resolution timeline can run out of memory on a modest device.
Do I need an account?
No. There is no sign-up, and nothing to pay.
Does my footage get uploaded?
No. The files are read into the tab and processed there. The page does load ads, and the first export fetches the encoder from a public CDN, but your footage is not part of either request.
Can I come back and finish later?
No — the timeline lives in the tab. Closing or reloading the page clears it, because nothing is stored on a server. Export before you leave.

Single-purpose tools

If you only need one job done, these are quicker than opening the full editor.
