Replay: The Ultimate Solution for Converting Video Designs to Production-Ready Code

TL;DR: Replay uses video analysis with Gemini to reconstruct functional UI code, understanding user behavior beyond just visual representations.

Stop Designing in a Vacuum: Convert Video Mockups to Code with Replay#

We've all been there: painstakingly crafting UI mockups, only to face a frustrating translation process to actual, functional code. Static screenshots and design tools often fall short, missing the crucial nuances of user interaction and intended behavior. The result? Wasted time, misinterpretations, and a final product that doesn't quite hit the mark.

Replay changes the game. It's a video-to-code engine that leverages the power of Gemini to reconstruct working UI directly from screen recordings. It's about more than just visual conversion; Replay understands how a user interacts with the design, allowing for behavior-driven reconstruction.

The Problem with Screenshot-to-Code#

Screenshot-to-code tools have limitations. They can generate basic visual layouts, but they lack the contextual understanding of user flows and dynamic interactions. They see a static image; they don't understand the intent behind the clicks, hovers, and form submissions. This often leads to incomplete or incorrect code generation, requiring significant manual rework.

Consider this scenario: A user clicks a button, which triggers a modal window to appear. A screenshot-to-code tool might only capture the final state with the modal open. It won't understand the button click that triggered it, the animations involved, or the data flow behind the scenes. Replay, on the other hand, captures the entire sequence, allowing it to reconstruct the interaction accurately.

Replay: Behavior-Driven Reconstruction#

Replay takes a fundamentally different approach. By analyzing video recordings of user interactions, Replay understands the behavior driving the UI. This allows it to generate code that not only looks right but also functions as intended.

Here's a breakdown of how Replay's behavior-driven reconstruction works:

1. •Video Analysis: Replay analyzes the video, identifying UI elements, user actions (clicks, hovers, scrolls, form inputs), and state changes.
2. •Intent Inference: Using Gemini, Replay infers the user's intent behind each action. For example, it can distinguish between a simple click and a double-click, or recognize a form submission based on the entered data.
3. •Code Generation: Based on the analyzed behavior and inferred intent, Replay generates clean, functional code in your preferred framework (React, Vue, etc.).
4. •Refinement: Replay provides tools to refine the generated code, customize styling, and integrate with your existing codebase.

Key Features That Set Replay Apart#

Replay offers a range of powerful features designed to streamline the design-to-code workflow:

• •Multi-Page Generation: Replay can handle complex, multi-page applications, accurately capturing and reconstructing the navigation flow between pages.
• •Supabase Integration: Seamlessly integrate Replay with Supabase to generate code that interacts with your database.
• •Style Injection: Customize the look and feel of your generated UI by injecting custom CSS or using your preferred styling library (Tailwind CSS, Material UI, etc.).
• •Product Flow Maps: Visualize the user flow through your application, providing a clear overview of the interactions captured in the video.

Replay vs. the Competition#

Let's compare Replay to other popular code generation tools:

Getting Started with Replay: A Step-by-Step Guide#

Here's a simple example of how to use Replay to generate code from a video recording:

Step 1: Upload Your Video#

Upload your screen recording to the Replay platform. Ensure the video clearly captures the user interactions you want to reconstruct.

💡 Pro Tip: Record your video in high resolution for optimal results.

Step 2: Define the Target Area#

Use Replay's tools to define the specific area of the video you want to analyze. This helps to focus the reconstruction process and improve accuracy.

Step 3: Generate the Code#

Click the "Generate Code" button. Replay will analyze the video and generate the corresponding code.

Step 4: Review and Refine#

Review the generated code and make any necessary adjustments. You can customize the styling, add event handlers, and integrate with your existing codebase.

Step 5: Integrate with Your Project#

Copy the generated code into your project and start building!

Example Code Snippet#

Here's an example of code generated by Replay from a video recording of a simple form submission:

typescript
// React component generated by Replay
import React, { useState } from 'react';

const ContactForm = () => {
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');
  const [message, setMessage] = useState('');

  const handleSubmit = async (e) => {
    e.preventDefault();
    // Simulate API call
    try {
      const response = await fetch('/api/submit', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({ name, email, message }),
      });

      if (response.ok) {
        alert('Form submitted successfully!');
        setName('');
        setEmail('');
        setMessage('');
      } else {
        alert('Form submission failed.');
      }
    } catch (error) {
      console.error('Error submitting form:', error);
      alert('An error occurred while submitting the form.');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name:</label>
        <input
          type="text"
          id="name"
          value={name}
          onChange={(e) => setName(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <input
          type="email"
          id="email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="message">Message:</label>
        <textarea
          id="message"
          value={message}
          onChange={(e) => setMessage(e.target.value)}
        />
      </div>
      <button type="submit">Submit</button>
    </form>
  );
};

export default ContactForm;

This code accurately captures the form structure, input fields, and submission logic from the video recording. Replay even infers the need for state management using

hooks.

⚠️ Warning: While Replay generates high-quality code, it's essential to review and test the generated code thoroughly before deploying it to production.
