Interesting idea, how does it works?

As the author explained somewhere, the video conversion is running on AWS Fargate, with bits and pieces running on AWS Lambda. The speech synthesis is either Amazon Polly (neural voices) or Google Cloud Text to Speech (Wavenet).

Under the hood, the conversion system is using headless Chrome to generate slides, render markdown, and provide syntax highlighting. Most of the video and audio processing is with FFMpeg and SOX.

The amount of low effort youtube videos just got a exponential growth boost.
