System Requirements Document (SRD)

Project Name: golden-video

1. Introduction

The golden-video project aims to create a fully functional AI Video Dubbing Web App, inspired by Crayo AI, with a clean, modern UI and responsive design. This application will allow users to upload videos, select dubbing languages and voices, and generate professionally dubbed videos without watermarks. The focus is on simplicity, speed, and user experience, with temporary history storage for recent projects.

This document outlines the system requirements for the golden-video project, tailored for Arman Khan in India, ensuring locale-specific considerations such as language preferences (Hindi, Chinese, English) and responsive design for mobile devices.

2. System Overview

The golden-video platform will provide users with a seamless experience for dubbing videos into multiple languages using AI technologies. The system will feature:

• A drag-and-drop interface for video uploads.
• AI-powered speech-to-text, translation, and text-to-speech pipelines.
• Temporary history storage for recent projects without requiring user accounts.
• A modern, glassmorphism-inspired UI with dark mode support.
• Backend processing using FFmpeg and open-source APIs for audio/video manipulation.

The system will prioritize speed, functionality, and ease of use, ensuring users can quickly upload, process, and download their dubbed videos.

3. Functional Requirements

Core Features:

• As a User, I should be able to upload videos via drag-and-drop or file selection.
• As a User, I should be able to preview uploaded videos before processing.
• As a User, I should be able to select dubbing languages (Hindi, Chinese, English).
• As a User, I should be able to choose AI-generated voices (Male/Female).
• As a User, I should be able to start the dubbing process with a single button click.
• As a User, I should see a progress bar showing real-time processing status.
• As a User, I should be able to download the final dubbed video without watermarks.
• As a User, I should be able to view a temporary history of recently dubbed videos during my session.
• As a User, I should experience smooth animations and responsive design on both desktop and mobile devices.

Additional Features:

• As a User, I should be able to toggle between light and dark mode.
• As a User, I should see error messages for unsupported file formats or file size limits.
• As a User, I should experience fast processing with proper error handling.

4. User Personas

1. General User

• Description: Individuals looking to dub videos for personal or professional use.
• Goals: Upload videos, select dubbing options, and download dubbed videos quickly.
• Pain Points: Long processing times, complex UI, and watermarked outputs.

2. Guest User

• Description: Casual users exploring the platform without creating accounts.
• Goals: Test the dubbing functionality and download videos temporarily.
• Pain Points: Limited history storage and no permanent account features.

5. Visuals Colors and Theme

Color Palette:

The golden-video project will feature a unique, modern color palette inspired by the theme of "golden creativity and AI innovation":

• Background: #1E1E2F (Deep Midnight Blue)
• Surface: #2A2A40 (Charcoal Gray)
• Text: #F5F5FA (Soft White)
• Accent: #FFD700 (Golden Yellow)
• Muted Tones: #6C6C80 (Muted Slate)

This palette ensures a professional yet inviting aesthetic, with high contrast for readability and vibrant accents for interactive elements.

6. Signature Design Concept

Concept: Interactive "Golden Circuitry" Landing Page

The homepage will feature a dynamic, animated golden circuit board design that visually represents AI-powered innovation.

• Visuals:

  • A glowing circuit board pattern that pulses gently in golden hues (#FFD700).
  • Interactive nodes on the circuit board that light up when hovered over, revealing tooltips about features (e.g., "Upload Video," "Start Dubbing").
  • A central glowing orb that acts as the drag-and-drop upload zone, surrounded by animated ripples when a file is dragged over it.

• Animations:

  • Smooth transitions between sections as users scroll, with circuit lines connecting features dynamically.
  • Subtle particle effects that mimic sparks of creativity.

• Micro-Interactions:

  • Buttons with gradient fills that shift slightly when clicked.
  • Progress bar with a glowing effect that moves fluidly as the video processes.

This design will make the platform feel futuristic and engaging, leaving users with a memorable first impression.

7. Non-Functional Requirements

• Performance:

  • Process videos within 2-5 minutes for files under 100MB.
  • Ensure responsive design across devices (desktop, tablet, mobile).

• Scalability:

  • Support concurrent processing for multiple users.
  • Implement a queue system for large workloads.

• Security:

  • Ensure secure file uploads and temporary storage.
  • Automatically delete old files after processing.

• Reliability:

  • Handle errors gracefully with clear messages for users.
  • Maintain uptime of 99.9% for backend services.

8. Tech Stack

Frontend:

• React (Web)
• Tailwind CSS

Backend:

• Node.js (Express)

Database:

• MongoDB

Video Processing:

• FFmpeg

AI Models:
