JustEdit Video Editor

Professional Browser-Based Video Editing. A powerful video editing suite that runs entirely in the browser. Cut, trim, transform, add effects, and export — no downloads, no uploads, just edit.

Problem

Many video tools require uploads, installs, or heavyweight workflows. JustEdit explores professional editing directly in the browser.

Architecture

  • Browser-based editing surface with timeline, clip operations, overlays, and export flow.
  • Local media handling through browser APIs so files stay on the user device.
  • Canvas, WebCodecs, and FFmpeg.wasm provide the technical foundation for client-side media work.

Evidence

  • Live app: https://justedit.markvizion.com/
  • Live hosted browser video editor.
  • Timeline editing, effects, text overlays, audio handling, and export-oriented workflow.
  • Demonstrates creative tooling, browser media APIs, and production workflow understanding.

Tradeoffs

  • Browser performance varies by device and video size.
  • Client-side privacy adds engineering constraints around memory, encoding, and export speed.

Outcome

A functional creative tool that turns production pain into a direct browser workflow.
