Synthetic Screen Recording — render fake but perfect terminal demos via Remotion

[calesthio]

🎬 Your AI assistant now shoots flawless terminal demos — without touching your screen

New in OpenMontage: synthetic screen recording.

Tell the agent "walk me through the install" and it produces a terminal video like the one below — commands typing, output scrolling, notification pills popping — all rendered in Remotion. Nothing is captured. Your desktop, tray, and private windows stay private.

What this unlocks

• 🎯 Frame-perfect tutorials — every command lands exactly when the voiceover names it
• 🚀 Iterate in seconds, not hours — change a command, re-render. No reshoot, no OBS, no crop
• 🔒 Shareable by default — no taskbar, no notification leaks, no "let me cut that part out"
• ♻️ Deterministic — same input, same pixels, every time

Try it

clone the repo → open in your AI assistant → say: "make a 60-second install demo for X"

That's the whole loop. The agent knows when to use a real screen recorder vs the synthetic path. Pick a CLI tool, an npm package, a make target — anything terminal-driven is fair game.

Shipped in commit a36ce99. Reply with what you'd want to see demoed — we're collecting ideas for the next wave (chat transcripts, code editors, GitHub PRs…).

Here is a small demo of how I used this feature without screen recording anything for the project explainer video
