Downloading & Rendering

AETHER generates the animation code and previews it in the browser; the final MP4 is rendered on your own machine from a downloaded project. This is fast, free, and fully offline — the download is a complete, self-contained Remotion project with your assets bundled in.

Download the project

1. On the Animation tab, click Download Project (top-right of the Live Preview card).
2. A "Render on your machine" dialog opens with a download button for each OS: Windows, macOS and Linux.
3. Click your platform. The button shows a spinner while the ZIP is built, then your browser saves it (e.g. MyProject-windows.zip).

Each download is tailored to one OS and contains a single one-click launcher:

Nothing to download yet? Generate an animation first — see Creating Animations. The button needs a project in the workspace.

Render it (one-click)

You need Node.js 18 or newer installed.

1. Unzip the download.
2. Double-click the launcher for your OS (StartAnimation.bat / .command / .sh). It:
   • checks that Node.js is installed (and opens the download page if it isn't),
   • installs dependencies on first run (npm install — a one-time minute or two), and
   • opens Remotion Studio, where you can play, tweak and render your video.

macOS / Linux: if double-clicking is blocked or the file isn't executable, open a terminal in the folder and run chmod +x StartAnimation.command (or bash StartAnimation.sh) first.

Render it (manual / advanced)

Prefer the terminal? From the unzipped folder:

npm install        # first time only
npm run studio     # open Remotion Studio (preview + render)
# or render straight to a file:
npm run render     # writes out/video.mp4

npm run studio opens Remotion Studio — the local previewer where you press Render to export the MP4. npm run render renders directly to out/video.mp4.

What's in the download

• The full Remotion project: package.json, tsconfig.json, remotion.config.ts and src/….
• Your assets bundled under public/ (referenced via staticFile(...)), so the render matches the preview and works offline.
• A platform-specific README.md with these same instructions.

Next steps

• Creating Animations — refine before you export.
• Motion Director — plan a stronger video up front.
