Subvert

Generate subtitles, chapters, and summaries of videos in seconds with the help of OpenAI.

🚧 This is very much a work-in-progress, please create issues for bugs if they appear 🚧

Getting started

You'll need:

• Docker installed on your local machine
• An OpenAI API key

Subvert is self-contained in a single Docker image and can be started with a one-line command:

docker run -it -p 80:8080 -e OPENAI_API_KEY=sk-123abc aschmelyun/subvert

This will boot up a server running the application and make it available to your machine at http://localhost.

How it works

After selecting a video file to process, you have the option of choosing whether you also want to generate chapters and a summary.

Your video is sent to an API where the audio is extracted from it using FFMpeg, and then sent to OpenAI's Whisper model for transcription into the common vtt format.

If you chose to select chapters or a summary, that transcript is then sent to a ChatGPT model for processing into concise chapters of the length you wanted, and a brief summary that would fit in something like a YouTube description.

Configuration

You can adjust a few parameters in the container by passing in environment variables with your command using additional -e flags. Here are the current ones you can add:

• OPENAI_API_KEY (required) - Sets the key responsible for communication with OpenAI's APIs. No default.
• UPLOAD_MAX_FILESIZE - Changes PHP's UPLOAD_MAX_FILESIZE setting. Default: 256M
• MEMORY_LIMIT - Changes PHP's MEMORY_LIMIT setting. Default: 512M

Starting from source

Alternative, if you have PHP 8.1+ and npm installed on your local machine, you can boot the application up directly from the source code instead.

First, check out this repo to your desired location. Then, navigate to the src directory and run:

./startup.sh

Alternatively, you can run the commands inside of the startup.sh script individually for the same result.

Deploying

Because this project is contained in a single Dockerfile, it can be deployed immediately to any server provisioned with Docker. Alternatively, the Subvert Docker image can be ran on cloud instances via AWS, Azure, GCP, Fly.io, etc.

Note: This image currently only exposes the insecure :80 http port.
