I Built a YouTube Shorts Generator with AI — Here's How

Source: Dev.to

The Problem

Creating YouTube Shorts consistently is time‑consuming. You need to design animations, render videos, and repeat the process for every single short. I wanted a pipeline where I could just change the data and get a brand‑new video automatically.

The Solution: Remotion + Claude Code

I combined two powerful tools:

• Remotion – A React‑based framework that lets you create videos programmatically using code. Think of it as writing React components, but the output is an MP4 video instead of a web page.
• Claude Code – Anthropic’s AI coding assistant that lives in your terminal. I used it to build the entire Remotion project through natural‑language prompts.

How It Works

1. Set up a Remotion project and define your video template with React components.
2. Use Claude Code to iterate on the design—adding smooth animations, emojis, particle effects, and custom colour schemes through simple conversational prompts.
3. Feed a JSON file with your content, and Remotion renders it to MP4.

The best part? Changing the JSON data gives you a completely new video—no recoding needed.

What I Covered in the Full Tutorial

The full video tutorial covers everything from setting up the Remotion project, walking through Remotion Studio, a live building session with Claude Code, iterating on animations and visual effects, and rendering the final MP4 output.
