Remotion Antigravity: Free AI Video Creation

Remotion Antigravity is the free combo that lets you build AI animations and videos inside Google's free IDE — here's the walkthrough.

If you want free AI video creation inside Google's ecosystem, this is the setup.

This post covers:

What Remotion Antigravity is.
How to combine them.
Building your first animation.
Real examples of what's possible.

The Quick Pitch

Two free tools, combined.

Google Antigravity

Google's free IDE.

Built-in agent capability.

Free credits/tokens.

Remotion

Free open-source video creation library.

Code-based animations and videos.

Combined: free AI video creation inside a free IDE.

For solo operators on a budget, this is the cheapest path to AI video.

Why This Combo Works

Three reasons.

1 — Free + free = free

No subscriptions.

Google Antigravity is free.

Remotion is free.

Total cost: $0.

2 — Antigravity has built-in AI

You don't need a separate Claude Code subscription.

Antigravity's AI agent handles the build.

3 — Local + free credits

Antigravity gives you free credits to use.

For solo operators, this stretches further than paid tools.

Setting Up Remotion Antigravity

Quick walkthrough.

Step 1 — Install Google Antigravity

Free download from Google.

Install like any IDE.

Step 2 — Open Antigravity

Pick a project folder.

Or create new.

Step 3 — Install Remotion skill

In Antigravity's chat, paste the Remotion skill install command:

npx skills add dev/skills/skill/remotion

Antigravity's agent runs the install.

If it gets stuck, you can also use Claude Code in a separate terminal as backup.

Step 4 — Create A Remotion Project

npx create-video latest

Then:

npm install

Step 5 — Build Your First Animation

In Antigravity's chat:

"Create a beautiful video animation for [topic]. Make it modern and engaging."

Antigravity's agent generates the Remotion code.

Live preview appears.

Step 6 — Iterate

Don't like something?

"Make the title bigger."

"Change to dark mode."

"Add a transition between scenes."

Antigravity updates code in real time.

Step 7 — Render

When happy:

npx remotion render

You get a finished MP4.

Building Animations From Existing Designs

A specific use case.

1 — Take a screenshot of an existing design

E.g. a website you want to promote.

2 — Paste in Antigravity chat

"Create a beautiful video animation for this page."

Reference the screenshot.

3 — Antigravity generates the animation

Based on what it sees in the design.

Brand colours preserved.

Layout informed.

4 — Render and embed

You can drop the video back into the website.

Promotional video done.

Vibe Coding Animations

This is the broader pattern.

You don't write code.

You describe what you want.

Antigravity's agent + Remotion build it.

This is similar to Claude Code Remotion but using Google's free IDE.

Two Terminals For Stability

Pro tip from real testing.

Sometimes Antigravity's chat struggles.

Run Claude Code in a separate terminal as backup.

If Antigravity fails:

Try Claude Code with the same prompt.
One usually succeeds.

This gives you redundancy.

Real Examples Of What You Can Build

From the video.

Logo animations

Take your existing logo.

"Animate this for an SEO-themed video."

Get a clean animated version.

Page promo videos

Screenshot a website page.

"Create a 30-second video promoting this."

Get a finished promo.

5-second intros

"Create a 5-second coffee shop introduction video."

Quick branded intros.

Custom animations

Anything you can describe.

Why Free Matters

Three implications.

1 — Solo operators can afford it

No subscription = no monthly cost.

For tight budgets, this is essential.

2 — More iteration

Free = unlimited (within Antigravity's free credits).

Generate variants.

A/B test.

3 — Lowers barrier to professional video

Used to need expensive software.

Now needs a free IDE.

What You Get After Setup

A complete free AI video pipeline:

Antigravity for IDE + AI agent.
Remotion for video framework.
Claude Code as backup.

Total cost: $0.

Total capability: real video production.

What This Replaces

Free Remotion Antigravity replaces:

Premiere Pro subscription (£20/month).
Final Cut Pro (£300 one-time).
Hiring video editors (£200-2,000/video).

For most solo operators, the savings are significant.

Common Setup Issues

1. Antigravity chat fails on install.

Use Claude Code in separate terminal as backup.

2. Remotion preview won't open.

Make sure no other apps using port 3000.

3. Render fails.

Check disk space.

Check Remotion project structure.

4. Antigravity runs out of free credits.

Either upgrade or switch to Claude Code temporarily.

Daily Reality

What it looks like running daily.

Idea → 1 minute.
Prompt Antigravity → 1 minute.
Build → 2-5 minutes.
Iterate → 5-10 minutes.
Render → 1-2 minutes.

15-20 minutes per video.

Free.

Multiple per day if needed.
