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.

Connected to the rest of KroxFlow

Not an island — a surface of the OS

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.

Multi-track. Canvas compositor. Real export. Everything the job asks of a modern NLE — with none of the install friction.
