How it works
01

Import

Drag from KroxDAM — proxy pipeline gives you 720p scrubbing instantly.

02

Arrange

Multi-track timeline with snap, split, ripple. Drag to slip clips.

03

Compose

Transform overlay on the program monitor — scale, rotate, crop, text.

04

Inspect

Every clip has an inspector — fade, opacity, transform, text content.

05

Export

WebM/VP9 via captureStream. Progress + cancel + quality presets.

What's inside

The NLE chops, without the desktop install

Multi-track timeline

Unlimited tracks, snap-to-clip (8px), split on playhead, context menus, keyboard shortcuts.

Canvas compositor

Video pool + image cache + RAF playback loop. Per-clip fade, crop, transform, text rendering.

Transform overlay

Drag, scale, rotate handles on the program monitor. Double-click to edit text inline.

Inspector panel

Context-sensitive per media type — audio volume, text styling, fade, clip transform.

Real export

captureStream + MediaRecorder. Download a WebM file. Safari check. Race-free teardown.

Zustand store

50-entry undo/redo, clip duplication, copy/paste, split, snap toggle, auto-save status.

Proxy pipeline

Every video asset has a 720p MP4 proxy — scrubbing never chokes on 4K source.

QA hardened

Every critical + high QA finding patched — TopBar selector, TransformOverlay, MediaTab auth, TextTab race.

KroxDAM

Drag clips straight from collections. The editor reads proxy_url for scrubbing, fullSrc for export.

KroxView

Ship a cut to review — comments come back as timeline markers at their timecodes.

→
KroxForge

Generated shots from the canvas land in the library and drop onto the timeline ready to cut.

→
Premiere CEP

Hand off to Premiere Pro when the job calls for a finishing pass. Selected clips export to Premiere XML.

KroxEdit

Edit in the browser. Ship faster.
