Parallel Synthesis Studios

Edit film, audio, and generated
media in the terminal

A keyboard-first clip and timeline editor. A multitrack arrangement, a session grid, real audio waveforms, a built-in co-pilot, and generative video. One tool, one keyboard.

Every frame of this reel was arranged and rendered in Parallel Synth.

What it is

A studio that lives in your terminal

Every video, voice take, music bed, and generated shot is a clip on a track. You build and refine three ways at once, driven by keys, not menus.

▓▓▓░░▓▓

Multitrack timeline

Arrange clips on video and audio lanes. Gaps fill with black. Non-destructive from end to end.

▶ ▶ ▶

Session grid

Named scenes you fire together. Build an opener, an act, an outro, and trigger them as blocks.

: talk

Plain-language co-pilot

Say what you want in plain words. Watch it call the same edit tools you use and build the timeline live.

▁▂▃▅▇█

Real audio waveforms

Decoded from the actual samples and drawn in text. Fade, split, normalize, scrub, and play in place.

gen ⋯

Generative pool

Generate title cards, tones, and video shots straight into your media pool, ready to drop on the timeline.

→ mp4

Render with ffmpeg

One command renders your program to a finished file. No timeline export dance, no round trips.

How it works

From blank to finished in three moves

01 · talk

Say it or type it

Talk to the co-pilot in plain words, or drive it with terse commands. Both edit the same timeline, and you watch every step land.

02 · build

Generate and arrange

Start from a template, pull in footage, generate slates, tones, and shots, and lay them on the tracks. Undo anything.

03 · ship

Render or serve

One command renders a finished file. Or serve the whole studio to a browser tab for anyone who does not live in a terminal.

Parallel Synth waveform view
See what you hear

Waveforms, in text

Select any clip and its waveform fills the scope. Audio lanes render their own waveform inline, so the timeline shows you the sound, not just a block.

Generative, built in

Shots you did not have to film

Describe a shot and generate it into your pool, then drop it on the timeline like any other clip. This frame was generated inside the app.

The same studio, in a tab

Not a terminal person? Parallel Synth runs in the browser too, from the exact same engine. Nothing to install for your team.

Made by the same hands

One person, one toolchain

Parallel Synth is built by Michael Crowe, who also runs Southwest Mushrooms and builds the Crowe Logic platform. The launch films for those products are cut in this editor. From the grow room to the timeline, it is all the same workshop.
