Feature

A real editor, in a tab.

Aperture is a multi-lane NLE that happens to live in a browser. Every tool a desktop editor would give you is here — minus the download, the license server, and the workstation.

Five ideas. That's the whole vocabulary.

You don't need a course. Video editing is five ideas — and Aperture keeps each one obvious.

IDEA 01
Clips live on lanes

A lane is a row. Video on top, music underneath, captions below that. Things on higher lanes cover things below — like layers of paper.

IDEA 02
Cuts remove time

Split a clip where you want it to change (the razor), delete the part you don't want. What's left joins up — that's a cut.

IDEA 03
Fades make it smooth

A crossfade melts the end of one clip into the start of the next. Dip to black tells the viewer a chapter ended.

IDEA 03
Speed is a slider

¼× for drama, 4× for a timelapse. The audio stays honest or goes silent — you choose.

IDEA 05
Render makes it real

Your sequence is a recipe. Render = the server bakes it into one clean video file. You keep editing while it bakes.

Hands on

If you've edited before, your hands already know this.

  • J-K-L shuttle

    J rewinds, K stops, L plays. Tap twice for fast. Every pro's muscle memory, intact.

  • Arrow keys step frames

    Left and right move one frame at a time. Precision without zooming.

  • Snap on / snap off

    One toggle. Clips click to edges and playhead when it's on, float free when it's off.

  • Markers & zoom

    Drop a marker to mean "check this later". Zoom slider with a fit button keeps the timeline honest.

  • Undo everything

    Undo/redo with real depth. Copy, paste, duplicate clips (Ctrl+C/V/D). Shift-click multi-select for bulk fades or deletes.

  • Autosave always

    Dirty indicator, Ctrl+S anywhere, guard on close. Close the tab at the gate; resume at home.

Feature · Browser NLE

J-K-L: three keys, thirty years of muscle memory.

Your hands already know this editor — snap, markers, frame stepping, zoom-to-fit. The only thing we could not port from your workstation was the fan noise.

Feel the shuttle

Your laptop edits. Our server delivers.

Here's the trick that makes a browser feel like a workstation: two engines. The browser composites live, so playback feels instant. The server conforms with ffmpeg, so exports are consistent and professional — every time, on every machine.

  • Dip-to-black and slide transitions between clips — identical in preview and export
  • Position keyframes — capture +pos at the playhead; clips animate between keys in preview and export
  • Speed ramps from ¼× to 4×
  • Per-clip transforms: position, scale, rotation
  • Chroma key (green screen) at export
  • Text and title track — canvas in browser, drawtext on server
  • Freeze frames, image clips, speed ramps
  • Audio finishing: per-clip gain, fades, auto-duck under speech, clean-audio denoise at export
  • Loudness normalize at export — −14 LUFS / −1.5 dBTP (production render measured −13.8)
  • Draft renders for speed, master renders for delivery
  • Render history with progress and download

"A workstation used to be a machine. Now it's a tab — and the tower is in the cloud."
