Show HN: E3d-pod2vid – AI pipeline that turns podcasts into YouTube-ready videos (github.com)

E3d Maps has launched an innovative AI pipeline called E3d-pod2vid that transforms podcast audio files into YouTube-ready videos. The system utilizes advanced technologies such as speaker diarization from AssemblyAI and content generation from GPT-4o-mini to select semantically relevant B-roll footage from Pexels for each segment of audio. This fully automated pipeline includes features like burned-in subtitles, optional text-to-speech (TTS) voice replacements for original audio, and straightforward social media posting capabilities across platforms like Discord, Telegram, X, and LinkedIn. This announcement is significant for the AI/ML community as it streamlines the podcast-to-video conversion process, saving creators time and effort while enhancing content accessibility and engagement. The pipeline’s architecture, which allows caching of queries and results, promotes efficiency and cost-effectiveness by minimizing API calls during re-runs or modifications. With simple commands for setup and execution, this tool democratizes video production for podcasters, making it easier to reach broader audiences on YouTube and social media while maintaining quality and coherence in visual storytelling.
