tube-crafter

Generate a video from a topic, or a script you already have.

Installation

npm install -g tube-crafter

Prerequisites

• ffmpeg must be installed
• OPENAI_API_KEY must be set in your environment
• Your machine must be able to access Google Cloud (instructions)

Usage

tube-crafter --topic "red squirrels"
tube-crafter --script my-script.md

When you run the command it will create an output directory in the current directory, and a timestamped directory inside for each run. The final video is located at e.g. output/2023-08-18T11-33-06-013Z/output.mp4.

How it works

1. Creates a video script from the topic provided (or uses provided script)
2. Splits the script into "text lines" (paragraphs and headings)
3. Creates a text-to-speech MP3 for each text line
4. Creates an image for each text line (if heading, text shown in image)
5. Creates a video for each text line (using the MP3 and image)
6. Concatenates all the videos into a single video
