Build a Realistic AI Podcast

An overview and tutorial for a free, open-source media-processing API (NCAA toolkit) that can run locally or on cloud providers like DigitalOcean, Google Cloud, or AWS. It handles audio and video tasks—transcoding, concatenation, transcription to text/SRT, and automatic captioning—while bundling local services (NADN and Min.io) to manage processing and file storage for cost-effective media workflows.

– Deployment & cost: Run locally for free or deploy on low-cost clouds (DigitalOcean, Google Cloud, AWS) to avoid per-request API fees.
– Core features: Audio and image processing, media transcoding, concatenating audio files, transcription to text/SRT, and automatic video captioning.
– Bundled services: Installs NADN locally and includes Min.io for file storage, removing the need for separate paid storage or transcription services.
– Use cases: Useful for creators and developers processing many media files who want a cost-effective alternative to multiple paid API services; the video references install instructions for common cloud platforms.

Quotes:

This is a free API you can run on the cloud or locally.

A really popular feature here is to caption your videos.

It’s a lot cheaper than signing up for a bunch of different API services.
