System Requirements Document (SRD)

1. Introduction

This document outlines the system requirements for the development of a project aimed at creating AI-generated videos based on user-provided stories or scenarios. The project will focus on enabling users to input their stories and generate visually appealing, animated videos using AI technologies.

2. System Overview

The system will allow users to input a story or scenario, which will then be processed by AI models to generate an animated video. The system will include features for story input, video generation, customization, and sharing. It will cater to various user personas such as general users, administrators, and guests. The system will leverage advanced AI models for video generation and user-friendly interaction.

3. Functional Requirements as Story Points

• As User I should be able to input a story or scenario in text format.
• As User I should be able to select themes or styles for the video (e.g., cartoon, realistic, artistic).
• As User I should be able to preview the generated video before finalizing.
• As User I should be able to download or share the generated video directly from the platform.
• As Admin I should be able to manage user accounts and monitor system usage.
• As Admin I should be able to update AI models and themes available for video generation.
• As Guest I should be able to explore sample videos and understand the system's capabilities.
• As User I should be able to receive a confirmation message or notification when the video is ready.

4. User Personas

1. User

• Primary user of the system.
• Inputs stories and generates videos.
• Can customize video themes and styles.
• Downloads or shares videos.

2. Admin

• Manages the system backend.
• Updates AI models and themes.
• Monitors user activity and system performance.

3. Guest

• Explores sample videos.
• Learns about the system's features.
• Limited access without registration.

5. Visuals Colors and Theme

The system will use a vibrant and engaging color palette to appeal to users of all ages, especially children and creative individuals. Suggested color theme:

• Primary Colors: Sky Blue (#87CEEB), Sunshine Yellow (#FFD700), Grass Green (#32CD32)
• Secondary Colors: Coral Pink (#FF7F50), Lavender Purple (#E6E6FA), Soft Orange (#FFA07A)
• Background: White (#FFFFFF) or Light Gray (#F5F5F5)
• Text: Dark Gray (#333333) for readability

6. Non-Functional Requirements

• The system should generate videos within 2-5 minutes of story submission.
• The system should support high-resolution video output (1080p or higher).
• The system should ensure data security and privacy for user-submitted stories.
• The system should be scalable to handle multiple video generation requests simultaneously.
• The system should have a user-friendly interface with intuitive navigation.

7. Tech Stack

Frontend

• React for Web

Backend

• Python
• FastAPI

Database RDBMS

• MySQL, using Alembic for migrations

AI Models

• Google Nano Banana for image generation
• Gemini 3 Pro for friendly response
• GPT 5.2 for user-friendly interaction

AI Tools

• Langchain
• Litellm for LLM Routing

Local Orchestration

• Docker
• docker-compose

Server-side Orchestration

• Kubernetes

8. Assumptions and Constraints

• The system assumes users will provide stories in text format only.
• The system assumes users will have access to stable internet for video generation.
• The system is constrained by the capabilities of the AI models used for video generation.
• The system will initially support English and Hindi languages for story input.

9. Glossary

• AI Video Generation: The process of creating animated videos using artificial intelligence technologies.
• Story Input: Text-based user-provided content that serves as the basis for video generation.
• Themes: Visual styles or aesthetics applied to the generated video.
• Preview: A temporary version of the video shown to the user before finalizing.
• LLM Routing: Large Language Model routing for efficient AI model selection.

This updated SRD incorporates the new requirement for AI video creation functionality and aligns with the user's request.
