Replay AI: Generate Blazor Components from a Video Recording

TL;DR: Replay uses AI to analyze video recordings of UI interactions and generate fully functional Blazor components, capturing not just the visual layout but also the intended user behavior.

Stop Designing, Start Replaying: Blazor Components from Video with Replay AI#

The traditional design-to-code workflow is broken. Hours are wasted translating mockups and wireframes into functional components, often losing crucial user interaction details in the process. Screenshot-to-code tools offer a marginal improvement, but they only capture static visuals, missing the dynamic behavior that defines a great user experience.

Enter Replay: a revolutionary video-to-code engine powered by Gemini. Replay doesn't just see pixels; it understands intent. By analyzing video recordings of UI interactions, Replay reconstructs working Blazor components, capturing the nuances of user behavior and generating code that's not only visually accurate but also functionally complete.

Why Video-to-Code? Behavior-Driven Reconstruction#

Replay's core innovation lies in its "Behavior-Driven Reconstruction" approach. Instead of relying on static images, Replay treats video as the source of truth. This allows the AI to understand:

• •User flows across multiple pages
• •Dynamic state changes triggered by user actions
• •The intended logic behind UI elements

This approach unlocks a new level of efficiency and accuracy in UI development, bridging the gap between design and implementation.

Generating Blazor Components: A Step-by-Step Guide#

Let's walk through the process of generating Blazor components from a video recording using Replay.

Step 1: Recording the UI Interaction#

The first step is to record a video of the UI interaction you want to reconstruct as a Blazor component. This could be a recording of:

• •A user flow in an existing application
• •A prototype demonstration
• •A whiteboard session outlining the desired behavior

💡 Pro Tip: Ensure the video is clear and stable, with consistent lighting. A screen recording tool like OBS Studio or even a quick recording on your phone is suitable. Narrating your actions in the recording can also significantly improve Replay's understanding of the intended behavior.

Step 2: Uploading and Processing with Replay#

Once you have your video, upload it to the Replay platform. Replay will then analyze the video, identifying UI elements, user actions, and state transitions. This process leverages Gemini's advanced video understanding capabilities to extract semantic information from the visual data.

📝 Note: The processing time depends on the length and complexity of the video. You'll receive a notification when the analysis is complete.

Step 3: Code Generation and Customization#

After processing, Replay generates the corresponding Blazor component code. This code includes:

• •HTML markup for the UI elements
• •C# code for handling user interactions and state management
• •CSS styles for visual presentation

You can then review and customize the generated code to fit your specific requirements.

csharp
// Example Blazor component generated by Replay
@page "/counter"

<h1>Counter</h1>

<p>Current count: @currentCount</p>

<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>

@code {
    private int currentCount = 0;

    private void IncrementCount()
    {
        currentCount++;
    }
}

⚠️ Warning: While Replay strives for accuracy, the generated code may require some manual adjustments to ensure optimal performance and maintainability. Consider it a highly advanced starting point, not a finished product.

Step 4: Integration with Your Blazor Application#

Finally, integrate the generated Blazor component into your application. This involves:

1. •Copying the generated code into your Blazor project.
2. •Adding any necessary dependencies.
3. •Modifying the component to fit your application's architecture and styling.

Advanced Features: Beyond Basic Code Generation#

Replay offers a range of advanced features that go beyond basic code generation:

• •Multi-Page Generation: Reconstruct complex user flows spanning multiple pages.
• •Supabase Integration: Seamlessly integrate with your Supabase backend for data management.
• •Style Injection: Apply custom styles to the generated components.
• •Product Flow Maps: Visualize the reconstructed user flows for better understanding and collaboration.

Replay vs. Traditional Methods: A Clear Advantage#

Let's compare Replay to traditional UI development methods:

Replay significantly reduces development time, improves accuracy, and facilitates collaboration by providing a shared understanding of user behavior.

Real-World Use Cases#

Replay can be used in a variety of scenarios, including:

• •Rapid Prototyping: Quickly generate working prototypes from video recordings of whiteboard sessions or user interviews.
• •Legacy System Modernization: Reconstruct UI components from existing applications without access to the original source code.
• •User Testing and Feedback: Analyze user recordings to identify areas for improvement and generate updated UI components.
• •Training Material Creation: Easily convert product demos into interactive training modules.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for higher usage and access to advanced features. Check the Replay pricing page for details.

How is Replay different from v0.dev?#

While both tools aim to generate code from visual input, Replay focuses on video as the primary input, enabling it to capture user behavior and generate more functional and dynamic components. v0.dev primarily relies on text prompts and image analysis. Replay's behavior-driven reconstruction provides a significant advantage in terms of accuracy and functionality.

What Blazor UI frameworks are supported?#

Replay can generate Blazor components compatible with various UI frameworks, including MudBlazor, Ant Design Blazor, and Bootstrap Blazor. You can specify your preferred framework during the code generation process.

What video formats are supported?#

Replay supports common video formats such as MP4, MOV, and AVI.
