Ragtube

Ragtube

Ragtube is an intelligent video processing and question-answering system that leverages advanced AI models to transcribe audio, analyze content, and provide insightful answers to user queries about video content.

Features

  • Audio transcription from video URLs
  • Text chunking for efficient processing
  • Integration with advanced language models for question answering
  • S3 storage for temporary audio files
  • YouTube video downloading capabilities

How It Works

  1. Video Download: The system downloads the audio from a given YouTube video URL.
  2. Audio Transcription: The audio is transcribed using a fast Whisper model.
  3. Text Processing: The transcription is chunked into manageable pieces.
  4. Vectorization and Storage: The chunks are vectorized and stored in a vector database for efficient retrieval.
  5. Question Answering: Users can ask questions about the video content. The system queries the vector database to retrieve relevant context and uses a large language model (Meta-LLaMA 3.1) to generate answers based on this context.

Usage

To use Ragtube, you'll need to set up the necessary environment and dependencies. Here's a basic guide:

Setup

  1. Create the infrastructure first by running:

    make create-stack

  2. Set the following environment variables in a local.env file in the project root:

    REPLICATE_API_TOKEN=your_replicate_api_token
PINECONE_API_KEY=your_pinecone_api_key
VIDEO_BUCKET=your_s3_bucket_name
SQS_QUEUE_URL=your_sqs_queue_url
SQS_QUEUE_ARN=your_sqs_queue_arn

    Replace the placeholder values with your actual credentials and resources.

  3. Install the required packages (exact requirements to be specified in a requirements.txt file).

  4. Set up your AWS credentials for S3 access.

  5. Ensure you have the necessary API keys for the AI models used (Replicate API key).

  6. Run the application using the following make commands:

    • To start the development server:

      make dev

    • To run tests:

      make test

    • To deploy the application:

      make deploy

    • To clean up deployment resources:

      make clean

These commands simplify the process of running, testing, and deploying the Ragtube application. Make sure you have make installed on your system and that you're in the project's root directory when running these commands.
