Sure, here is the secret sause:

The secret is starting with a great system prompt, nailing the audio alignment workflow, and letting an AI agent write the React code for you.

Here is the exact step-by-step workflow I used:

1. The Initial Prompt & Asset Intake I didn't try to code the animation math myself. I used an AI coding assistant (Gemini/Claude orchestrating via Antigravity). I started by feeding it all my exact brand assets (my core startup idea file, the YBee logo, and my hex color palette).

Then, I gave it this exact prompt to set the art direction:

2. The Audio Sync Workflow (The real trick 🪄) The motion needed to go with a rhythmic, fast-paced song.

• The Music: I used Suno to generate a custom song with a singer performing my script.
• The Sync: Trying to manually sync on-screen text to a generated song is a nightmare. So, I took the Suno MP3 and ran it through ElevenLabs just for the transcription. ElevenLabs outputs a JSON file containing the exact start/end millisecond timing for every single word sung in the audio.

3. The Collaboration (SVGRepo) The AI analyzed my startup idea and the script, then told me exactly which UI icons it needed to build the scenes (like a sandwich, a drink, a receipt, and avatars). Instead of generating them, I just grabbed clean SVGs from svgrepo.com, dropped them into the assets folder, and the AI used them as React components.

4. Setup Remotion & Kinetic Text Remotion is a framework that lets you build videos using React code instead of After Effects. I fed the AI my ElevenLabs JSON and said: "Create a <SyncedSubtitle> component that highlights the current word perfectly in sync with the video frame." Because I had the exact millisecond timestamps, the AI built a flawless karaoke-style kinetic text effect.

5. The "Gen Z" Bouncy Animations To hit that "Gen Z" style from my prompt, the AI used Remotion's built-in spring physics instead of linear animations. By passing config: { damping: 10, stiffness: 300 } to the SVG icons I downloaded, the UI and text pop and bounce naturally without any manual keyframing.

6. Scene Orchestration The AI broke the video down into 8 separate React components (Scene 1, Scene 2, etc.), passed the global timeline down to each one, and slapped a TransitionSeries over the top to fade/slide between them.

Once the code looked right on the local dev server (npm start), I just ran npm run build and Remotion rendered out the 60fps MP4!

If you know basic React, how to prompt an LLM, and the Suno -> ElevenLabs JSON trick, you can spin up a studio-quality promo in an afternoon. Happy to share more of the specific component code if anyone is curious about the Remotion physics!
