THE EDITOR · THE FREE, OFFLINE HALF

A non-linear editor that earns the name.

Multitrack timeline, the pro trims, a full colorist surface, keyframe automation, a real mixer, and structured captions — on a GPU playback engine that scrubs without pre-rendering. All of it free, offline, and account-less. The Director is optional.

THE PRO TRIMS

The muscle memory you already have.

Slip, roll, slide, ripple, blade — the same trim grammar the pro tools use, as typed operations in the engine. Blade and ripple are on the keys today; slip, roll and slide ride the Director, with their drag surfaces on the way. Teal is what moves; grey holds.

Slip

In and out move together — content shifts, the clip’s position holds.

Roll

The shared edit point moves — one grows, one shrinks, total length fixed.

Slide

The clip slides along the lane — its neighbors absorb the difference.

Ripple ⇧⌫

Delete a clip and the gap closes — everything downstream ripples in.

Blade S

Split a clip cleanly at the playhead — the fastest cut there is.

COLORIST

A real color page. Wheels, LUTs, scopes.

Lift-Gamma-Gain wheels and scalar grade controls, .cube LUTs, all read against a live waveform and vectorscope. This is the surface that separates a real editor from a filter stack.

MULTITRACK · AUDIO BUSES

Every bus has its own identity.

Video, dialogue, music, SFX and ambient — each lane carries a role color so a full mix stays legible at a glance.

Dialogue Music SFX Ambient
KEYFRAME AUTOMATION

Animate anything, on real curves.

Transform, grade, opacity, audio — every parameter takes keyframes with editable easing.

THE MIXER

Faders, ducking, loudness.

Per-bus channel strips, music that ducks under dialogue, and one meter that matters — peak on the master — read against your loudness target in the server render.

STRUCTURED CAPTIONS

Captions with structure, not guesses.

15 caption types with timing you edit by hand — burn them to the master, or ship a .srt sidecar.

GPU PLAYBACK ENGINE

Fast enough to stay in flow.

WebCodecs decode and WebGPU compositing mean grades, effects and generated clips composite on the fly — frame-accurate scrubbing, no pre-render.

168 fps
A spike from the Phase-0 playback gate — 1080p, four plain tracks, no effects or grade, on a discrete-GPU machine.
Frame-accurate scrub
Land on the exact frame every time — no rounding, no drift.

FREE · OFFLINE · ACCOUNT-LESS

All of this is the free half.

Everything on this page — the timeline, trims, colorist, keyframes, mixer, captions, the engine — runs on your device with no sign-in and no connection. Clips decode locally; nothing leaves your machine. The Director is the upgrade you can add, never the toll.
