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 AI co-pilot, and generative video. One tool, one keyboard.

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

AI co-pilot

Say what you want in plain language. 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 ASCII. Fade, split, normalize, scrub, and play in place.

gen ⋯

Generative pool

Generate title cards, tones, and video shots straight into your media pool with Azure Sora built in.

→ mp4

Render with ffmpeg

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

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 with Azure Sora, then drop it on the timeline like any other clip. This frame was generated inside the app.

Prefer a browser

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.
