Create videos with one command.

Pick a template, hand it your data, get an MP4 back — or a PNG — from your terminal or straight from your browser. Run it again tomorrow and you get the same pixels, frame for frame.

// how it works

One string is the whole layout

Rectangles subdivide a canvas — no pixels, no coordinates, just structure. The entire surface:

N() column split

N[] row split

F tile (rendered content)

> donates space forward

- intentional gap

X{Y} overlay

Your data fills the tiles

Every rectangle is a content slot: images, video, text, colors — or another template. Templates map JSON props to geometry, so a chart is data in, motion out.

--props '{"values": [72, 45, 88, 31, 66]}'

ffmpeg compiles it to pixels

The engine builds a deterministic render plan and ffmpeg executes it. Same inputs, same bytes — on your laptop or in CI. Output is an MP4 or PNG small enough to email. No browser in the pipeline.

// pricing

Free. No card, no account.

The full engine, every template, every resolution — nothing is locked behind a plan. Free renders carry a QR mark in the corner; $15/mo removes it.

// templates, by agent

Templates are agent-writable. Most of ours were.

A template is a file; the gate reviews it. That’s a loop a coding agent can run — and did, for the shipping library. With receipts.

See the receipts →

// one a day

An agent ships one template a day. Watch it work.

Scout, plan, build, critique, ship — and a gate that is code. Every template explains itself: the problem it found, the sources, how it was made, what it cost. Add the repo to Mosaic Desktop and use them.

// m0 & m0saic

m0 is the open layout language.

m0saic is the engine that compiles it — open language, open formats, open templates; commercial engine.

m0saic is not a video editor. It is a video compiler.
