Setup guide

From ZIP to first render in about 5 minutes

Everything you need to run your RenderComp templates. No coding experience required to get started.

  1. Install Node.js

    One time only

    Node.js is the free runtime that powers the templates. Skip this step if it is already installed.

    macOS

    Download the “LTS” installer from nodejs.org and run it. Keep every default option.

    Windows

    Download the “LTS” installer (.msi) from nodejs.org and run it. Keep every default option.

    nodejs.org →

    Check: open Terminal (Mac) or PowerShell (Windows) and run this — v18 or higher means you are ready.

    node -v

  2. Unzip your download

    Double-click the RenderComp ZIP from your download page (or email) to unzip it. Put the folder somewhere easy to find, like your Desktop.

  3. Open a terminal in that folder

    macOS

    Open Terminal (⌘+Space, type “Terminal”), type cd  (with a trailing space), drag the unzipped folder into the window, press Enter.

    Windows

    Open the unzipped folder in Explorer, click the address bar, type powershell, press Enter.

  4. Install and start

    Run these two commands, one after the other. The first install takes a few minutes.

    npm install
npm run dev

    Remotion Studio opens in your browser. If it does not, open the http://localhost:3000 link shown in the terminal.

  5. Pick, customize, render

    • ✓The left sidebar lists every template. Click one to play its preview.
    • ✓Change text and colors in the props panel on the right — or edit the template’s .tsx file.
    • ✓Click “Render” in Studio to export an MP4. Done.

    Only the very first render can take a few minutes — it downloads a render engine once. Every render after that is much faster.

If something goes wrong

“npm: command not found”

Node.js is not installed, or your terminal was opened before the install. Install the LTS version from step 1, then close and reopen the terminal and try again.

npm install fails partway

Check your internet connection and run npm install again. If you see a permissions error (EACCES), move the folder into your own user area (Desktop or Documents) and retry. Do not use sudo.

Windows says “running scripts is disabled”

Type cmd instead of powershell in the address bar to open Command Prompt, and run the same commands there.

The browser does not open / localhost:3000 does not respond

The terminal prints the actual URL (if another app is using port 3000, Studio picks a different one). Open that URL in your browser.

node -v shows an old version (below v18)

Install the latest LTS from nodejs.org and reopen the terminal.

Ask an AI (fastest route)

Copy the error message from your terminal, copy the help prompt below, and paste both into ChatGPT, Claude, or any AI assistant. It usually solves the problem in one reply.
