rising-bot System Requirements Document

Introduction

The rising-bot project aims to develop a web application that allows users to download YouTube videos or shorts by pasting the video link. The primary focus is on video downloads, with potential additional features like audio extraction and multi-format export options being evaluated for inclusion.

System Overview

The rising-bot application will provide users with a simple interface to download YouTube videos by entering the video URL. The system will process the URL and offer download options based on the user's preferences. The core functionality will focus on video downloading, with the possibility of expanding to include audio extraction and multiple format options.

Functional Requirements

• As a User, I want to paste a YouTube video link to initiate the download process.
• As a User, I want to download the video in its original format.
• As a User, I want to choose from different video quality options for download.
• As a User, I want to extract audio from the video, if the feature is included.
• As a User, I want to download the video in different formats, if the feature is included.

User Personas

• General User: An individual looking to download YouTube videos or shorts for offline viewing. They may also be interested in extracting audio or downloading videos in different formats if these features are available.

Core User Flows

• User pastes YouTube link -> selects video quality -> downloads video.
• User pastes YouTube link -> selects audio extraction (if available) -> downloads audio file.
• User pastes YouTube link -> selects desired format (if available) -> downloads video in chosen format.

Signature Design Concept

The homepage of rising-bot will feature an interactive "Video Galaxy" concept. Users will see a dynamic galaxy map where each star represents a different feature or section of the website. Hovering over a star will highlight its connections, and clicking will open a detailed view of that feature. The galaxy will rotate as users drag their cursor across the screen, creating an engaging and exploratory experience. This will be implemented using @react-three/fiber for 3D rendering and gsap for smooth animations and transitions.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, providing a layered depth effect as users scroll. Decorative elements such as stars and nebulae will move at different speeds, creating a sense of immersion. Key content will remain in the natural flow, ensuring readability and accessibility.

Non-Functional Requirements

• The application should support high traffic and concurrent downloads without performance degradation.
• The system must ensure data privacy and comply with relevant legal regulations regarding video downloading.
• The user interface should be responsive and accessible across various devices and screen sizes.

Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MongoDB
