In today's digital world, video content is king. From social media to corporate presentations, video is an essential part of communication. Managing and processing this video content has become a complex task that requires an intelligent and comprehensive approach.

Enter Langchain, a cutting-edge application designed to streamline video management through a system of specialized tools. With an array of functionalities, ranging from video indexing to keyword research and classification, Langchain is set to redefine how we interact with videos.

Langchain Architecture

The architecture of Langchain is designed with modularity and flexibility in mind. Here's a look at the classes that make up the system:

Video Indexing

  • VideoIndex: Acts as a container for videos, holding an array of Video objects.
  • Video: Represents a video file, including its source path, target location, metadata, frames, and associated keywords.

Image Processing

  • Frame: Encapsulates an individual frame within a video.
  • ResNet50Tool: A tool for classifying frames, based on the ResNet50 architecture.

Metadata Management

  • VideoMetadata: Holds detailed metadata for a video, including editorial information, categories, keywords, and more.
  • LangchainMetadataTagger: A tool responsible for generating metadata based on classification.

Keyword Management

  • Keyword: Represents an individual keyword.
  • SerpAPITool: A tool for researching keywords based on metadata.

Data Storage and Backup

  • WeaviateTool: Responsible for storing video data along with metadata and keywords.
  • SupabaseTool: A tool for backing up video, metadata, and keywords.


  • StreamlitTool: A tool for displaying video, metadata, and keywords.


  • Langchain: Acts as the orchestrator, managing tools and executing tasks.
  • Tool: An abstract class that defines the execution method for tools.

Workflow Overview

  1. Video Indexing: Videos are indexed and categorized.
  2. Classification: Frames are classified using the ResNet50Tool.
  3. Metadata Generation: Metadata is generated based on classification.
  4. Keyword Research: Keywords are researched using the SerpAPITool.
  5. Storage & Backup: Video, metadata, and keywords are stored and backed up.
  6. Display: Video, metadata, and keywords are displayed using StreamlitTool.


Langchain represents a novel approach to video management, combining the power of machine learning, data storage, and visualization into a single coherent system. Its modular architecture ensures flexibility and scalability, making it suitable for various applications.

Whether you are a content creator, a media company, or a technology enthusiast, Langchain offers an intelligent and efficient way to manage and process video content.

Get ready to experience the next generation of video management with Langchain, where innovation meets functionality.
