Summary This post demonstrates how to automatically transform a scientific paper (or any text/audio content) into a YouTube video using AI. We’ll leverage several powerful tools, including large language models (LLMs), Whisper for transcription, Stable Diffusion for image generation, and FFmpeg for video assembly. This process can streamline content creation and make research more accessible. Overview Our pipeline involves these steps: Audio Generation (Optional): If starting from a text document, we’ll use a text-to-speech service (like NotebookLM, or others) to create an audio narration.
