OpenMontage hit #1 on GitHub Trending (Repository of the Day) and it's fully open-source under AGPL-3.0. Here's the repo and everything you need to run it today:

"Turn your AI coding assistant into a full video production studio. Describe what you want in plain language — your agent handles research, scripting, asset generation, editing, and final composition." — OpenMontage README, github.com/calesthio/OpenMontage
What it made · real movies

Actual movies. Real motion, real sound — one sentence each.

This is the real thing. Each film was one sentence. OpenMontage wrote the story, filmed every shot with Google Veo 3.1 — genuine motion footage with synchronized audio — then laid the storyline and title cards over the top in Remotion, exactly like its "Signal From Tomorrow" demo. Turn your sound on and click play.

Dragon's Shadow
"A lone knight on a storm-lashed cliff as a dragon descends from the thunderclouds."
Veo 3.1 motion · Remotion storyline
Abandoned Odyssey
"An astronaut drifts toward a derelict alien ship as a light ignites inside."
Veo 3.1 motion · Remotion storyline
Blossom's Edge
"A samurai in a storm of cherry blossoms draws his katana as shadows close in."
Veo 3.1 motion · Remotion storyline
Abyssal Reverie
"A diver descends past a sunken city as a colossal whale emerges from the dark."
Veo 3.1 motion · Remotion storyline
Also made · cinematic trailers from AI stills

And film-grade trailers. From a single sentence each.

Don't have a video-gen key? OpenMontage still makes these — no motion model needed. One line each: it painted every frame with gpt-image-2, added cinematic camera motion, dramatic title cards, a color grade, and a score — then rendered it through its own CinematicRenderer. Not slideshows. Trailers. Click play on any of them.

Burning Bamboo
"A lone samurai walks through a burning bamboo forest at night, embers in the wind."

Derelict
"A colossal derelict spaceship drifting through the rings of a gas giant."
gpt-image-2 · CinematicRenderer
Frostfire
"An ancient dragon awakens inside a vast frozen mountain cathedral."

Neon Rain
"A lone figure walks through a neon-drenched, rain-soaked future Tokyo at night."

The Abyss
"A bioluminescent leviathan rises from the black abyss beneath an arctic ice shelf."

Signal From Tomorrow
OpenMontage's flagship — Veo motion clips + Hans-Zimmer-style score + Remotion composition.
motion-clip path · Veo
Thinking it?
"There's no way that's one prompt."
It is. Each trailer started as a single sentence. OpenMontage's agent turned it into a 5-shot plan, generated every frame with gpt-image-2, gave each shot real camera motion, dropped in the title cards, scored it, and rendered the whole thing through CinematicRenderer — the same composition behind "Signal From Tomorrow." One line in, a finished trailer out.

My story · why this got me

Making video used to be the worst part of my week.

Before

I wanted videos for my content, my products, my ads.

So I paid for three different SaaS tools.

I'd jump between tabs — script here, voiceover there, captions somewhere else.

Every clip was an upload-download-re-upload nightmare, and hours gone.

And half the "AI video" tools just slow-zoomed over stills and called it a video.

Then I pointed my coding agent at OpenMontage and typed one sentence.

After

Now I describe the video I want and walk away.

My agent researches it, writes it, finds the music, builds the scenes, and renders it.

The simple ones cost me nothing. The fancy ones cost a dollar or two.

No tab-juggling. No three subscriptions. One prompt, a finished file.

You can do this today. It's free, it's open, and it runs on the agent you already use.

Who's telling you this

Why I jumped on this one fast.

I run an AI-first SEO agency and teach thousands of operators how to wire AI into real businesses. Video is the channel everyone wants and nobody has time for. A free, open-source tool that turns my agent into a video team is exactly the kind of unlock I look for — so I tested it the day it trended.

Before you scroll on —

Commit to making one video today.

You've seen the proof. Real videos, made from a sentence, most of them free.

Here's the deal I want you to make with yourself.

Before you sleep tonight, you're going to clone OpenMontage, run one setup command, and ask your agent for one short video.

Just one. The free path. No keys, no spend.

Because the moment you watch your own agent hand you a finished video, the whole "I don't have time to make video" story is over.

The people who start today are the ones shipping daily video by next week. The people who bookmark it are the ones still paying three subscriptions in six months.

Be one of the people who starts.

Commit to making one video today. Free path. One prompt. Start tonight.

What it costs

Free out of the box. Cents if you want more.

With zero API keys, make setup already gives you real narration (Piper TTS), open archival footage (Archive.org, NASA, Wikimedia), Remotion + HyperFrames composition, FFmpeg post-production, and auto subtitles. Add a key and the price barely moves — these are OpenMontage's own published example costs:

Real videos, real costs — from OpenMontage's own examples
published per-video cost · axis floor $0 · these are full finished videos, not single clips
Ghibli-style anime
$0.15
Product ad (1 key)
$0.69
Pixar-style short
$1.33
My zero-key videos
$0.00

And a built-in budget governor means no surprise bills: it estimates cost before it spends, pauses for your OK above $0.50, and caps the whole job at $10 by default.

How video gets made now

The old way vs the new way.

Here's the shift OpenMontage forces, laid out plainly.

The old way
~hours, 3 subscriptions
  • Pay for a script tool, a voice tool, a caption tool
  • Jump between 4–5 tabs to make one clip
  • Upload, download, re-upload between every step
  • Settle for stills with a slow zoom and call it "AI video"
  • Pay per render, every time, forever
  • Result: hours gone, money out, generic output
The new way
~one prompt, $0–$2
  • Describe the video in one plain sentence
  • Your agent runs research → script → assets → edit → render
  • It picks the best tool for each step and logs why
  • Real footage or real animation — a slideshow gate blocks the cheap trick
  • The free path costs nothing; keys add cents, not subscriptions
  • Result: a finished video, on your terms, that you own
Run it yourself

Three lines and a sentence.

You need Python, FFmpeg, Node, and an AI coding assistant you already use (Claude Code, Cursor, Copilot, Windsurf, or Codex). Then:

# clone + set up — zero keys needed git clone https://github.com/calesthio/OpenMontage.git cd OpenMontage && make setup # open the folder in your AI coding assistant and just ask: "Make a 45-second animated explainer about why the sky is blue" "Make a 90s documentary montage about a city at 4am. Real footage only, no narration." "Here's a YouTube Short I love. Make me something like this, but about my product."

That's it. It researches with live web search, writes and narrates the script, finds royalty-free music, burns in word-level subtitles, and renders — then self-reviews the output before it ever shows you a frame.

Thinking it?
"I'm not technical enough to run a GitHub repo."
You're not running it — your agent is. You paste three lines once, then you talk to it in plain English like you already do. If you can open a folder in Cursor or Claude Code and type a sentence, you can run OpenMontage. The agent reads the instructions, picks the tools, and does the work.
The agent is the studio — give it a brain

Make OpenMontage part of a system that knows your business.

Agent OS — Claude, OpenClaw and Hermes connected

OpenMontage is only as good as the agent driving it. The Agent Operating System inside the AI Profit Boardroom connects Claude, OpenClaw, and Hermes into one dashboard with shared memory — so the agent making your videos already knows your brand, your voice, your goals, and your other tools. I've wired OpenMontage straight into it.

  • The full Agent OS zip — every prompt, the memory setup, the dashboard
  • Four live coaching calls a week with operators building with AI in production
  • Daily tutorials — including how to wire tools like OpenMontage in
  • A 30-day roadmap to set the whole system up step by step
  • A community of 3,600+ founders across 38 countries, online 24/7
  • A member map to connect with builders near you

Three beliefs to drop

What's been stopping you making video.

Wrong: "Making good video needs expensive tools and editing skills."

Right: OpenMontage is free and open-source, and your agent does the editing. The three videos above cost me nothing and never touched a timeline by hand.

Wrong: "Free AI video always looks like a cheap slideshow."

Right: OpenMontage refuses to ship a slideshow — a delivery-promise gate and slideshow-risk score block it. You get real animation or real footage, scored and self-reviewed before you see it.

Wrong: "I'll wait until there's a polished paid app for this."

Right: The paid apps lock you into one look, one provider, and a monthly fee. This is open, swaps any of 14 video providers freely, and the people learning it now will be making daily video while everyone else is still comparing subscriptions.

Don't take my word for it

158 pages of members who stopped paying for scattered tools and built one system instead — real businesses, real wins, written in their own words.
