How to Convert Video UX Design Mockups To Remix Web Applications with ReplayAI UI Scaling

TL;DR: Replay lets you convert video recordings of UX design mockups into fully functional Remix web applications, complete with UI scaling and behavior-driven logic.

The age of static prototypes is over. Your UX design mockups are dynamic, interactive experiences—often captured as videos. But translating those video recordings into real, working code? That's traditionally been a massive bottleneck. Enter Replay, the video-to-code engine that understands user intent, not just pixels.

From Video to Remix: A Revolution in UI Development#

Manually transcribing UX video mockups into code is tedious, error-prone, and frankly, a waste of valuable developer time. Screenshot-to-code tools offer a partial solution, but they lack the crucial ability to understand the flow and behavior demonstrated in the video. They only see static images.

Replay changes the game. By leveraging Gemini's advanced video analysis capabilities, Replay reconstructs UI elements and their interactions, generating clean, maintainable Remix code directly from your UX video mockups. This means you can go from concept to working prototype in a fraction of the time.

Why Remix? The Perfect Partner for Replay#

Remix is a full-stack web framework that embraces web standards and provides a fantastic developer experience. Its focus on data loading, routing, and server-side rendering makes it an ideal target for Replay's code generation. With Remix, you get:

• •Server-side Rendering (SSR): Improved SEO and faster initial load times.
• •Data Loading and Mutations: Built-in mechanisms for managing data flow.
• •Nested Routing: Simplified navigation and URL structure.
• •Progressive Enhancement: Ensures your application works even with JavaScript disabled.

The Power of Behavior-Driven Reconstruction#

Replay's "Behavior-Driven Reconstruction" is what sets it apart. It doesn't just look at the visual elements in your video; it analyzes the actions performed by the user. This allows Replay to infer the intended behavior of the UI and generate code that accurately reflects that behavior.

For example, if your video shows a user clicking a button and navigating to a new page, Replay will generate the necessary Remix route and event handler to replicate that behavior. This goes beyond simple visual reproduction; it's about understanding the intent behind the interaction.

Step-by-Step: Converting Your UX Video to a Remix App#

Here's how to use Replay to convert your UX video mockup into a fully functional Remix web application:

Step 1: Prepare Your UX Video#

Ensure your video is clear, well-lit, and accurately represents the desired user flow. Focus on capturing the interactions and transitions between different UI states.

💡 Pro Tip: A well-scripted video with intentional pauses between actions will yield the best results.

Step 2: Upload to Replay#

Create a Replay account and upload your UX video. Replay supports various video formats, including MP4, MOV, and WebM.

Step 3: Configure Project Settings#

Specify the target framework (Remix), desired UI scaling options, and any relevant Supabase integration details.

📝 Note: Replay offers fine-grained control over the generated code, allowing you to customize the output to match your specific project requirements.

Step 4: Let Replay Work Its Magic#

Replay will analyze your video and generate the Remix code. This process may take a few minutes, depending on the length and complexity of the video.

Step 5: Review and Refine the Generated Code#

Once the code generation is complete, review the generated Remix code in the Replay editor. You can make adjustments, add custom logic, and refine the UI elements as needed.

typescript
// Example: A generated Remix route for handling a form submission
import { ActionFunctionArgs, json } from "@remix-run/node";

export const action: ActionFunctionArgs = async ({ request }) => {
  const formData = await request.formData();
  const name = formData.get("name") as string;
  const email = formData.get("email") as string;

  // Process the form data (e.g., save to database)
  console.log(`Name: ${name}, Email: ${email}`);

  return json({ success: true });
};

export default function ContactRoute() {
  return (
    <form method="post">
      <label htmlFor="name">Name:</label>
      <input type="text" id="name" name="name" />

      <label htmlFor="email">Email:</label>
      <input type="email" id="email" name="email" />

      <button type="submit">Submit</button>
    </form>
  );
}

Step 6: Deploy Your Remix App#

Download the generated Remix code and deploy it to your preferred hosting platform (e.g., Netlify, Vercel, Fly.io).

UI Scaling: Adapting to Different Screen Sizes#

Replay automatically handles UI scaling based on the observed dimensions and layouts in your video. This ensures that your Remix application looks great on a variety of devices, from smartphones to desktop computers.

You can further customize the UI scaling behavior by specifying breakpoints and responsive design rules in the Replay editor.

Supabase Integration: Seamless Data Management#

Replay seamlessly integrates with Supabase, allowing you to connect your Remix application to a powerful, open-source database. You can define your data models in Supabase and use Replay to generate the necessary code for interacting with your database.

⚠️ Warning: Ensure you have a Supabase account and API keys configured before enabling Supabase integration in Replay.

Product Flow Maps: Visualizing User Journeys#

Replay generates interactive product flow maps that visualize the user journeys captured in your video. These maps provide a clear overview of the different screens and interactions within your application, making it easier to understand and refine the user experience.

Benefits of Using Replay#

• •Accelerated Development: Go from video mockup to working prototype in hours, not weeks.
• •Improved Code Quality: Replay generates clean, maintainable Remix code.
• •Enhanced Collaboration: Share video mockups and generated code with your team for seamless collaboration.
• •Reduced Costs: Automate the tedious task of manual code transcription.
• •Focus on Innovation: Free up your developers to focus on higher-level tasks and innovation.

typescript
// Example: Injecting custom styles into a component
const MyComponent = () => {
  return (
    <div style={{ backgroundColor: 'lightblue', padding: '10px' }}>
      <h1>Hello from MyComponent!</h1>
    </div>
  );
};

export default MyComponent;

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for more advanced features and usage.

How is Replay different from v0.dev?#

While both aim to accelerate UI development, Replay uses video as its source of truth, focusing on behavior-driven reconstruction. v0.dev relies on text prompts and AI generation, which can sometimes lack the precision and context captured in a real-world UX video. Replay understands what users are doing, not just what they say they want.

What frameworks does Replay support?#

Currently, Replay supports Remix and Next.js, with plans to add support for other popular frameworks in the future.

What kind of videos work best with Replay?#

Videos that clearly demonstrate user interactions and transitions between different UI states work best. Avoid videos with excessive camera movement or poor lighting.

Can I customize the generated code?#

Yes, Replay provides a code editor that allows you to make adjustments and add custom logic to the generated code.
