Building a REST API to scale processing

Tim McAleer is a producer at Ken Burns’s Florentine Films who is responsible for the technology and processes that power their documentary production. Rather than using AI to generate creative content, Tim has built custom AI-powered tools that automate the most tedious parts of documentary filmmaking: organizing and extracting metadata from tens of thousands of archival images, videos, and audio files. In this episode, Tim demonstrates how he’s transformed post-production workflows using AI to make vast archives of historical material actually usable and searchable.

What you’ll learn:

1. How Tim built an AI system that automatically extracts and embeds metadata into archival images and footage
2. The custom iOS app he created that transforms chaotic archival research into structured, searchable data
3. How AI-powered OCR is making previously illegible historical documents accessible
4. Why Tim uses different AI models for different tasks (Claude for coding, OpenAI for images, Whisper for audio)
5. How vector embeddings enable semantic search across massive documentary archives
6. A practical approach to building custom AI tools that solve specific workflow problems
7. Why AI is most valuable for automating tedious tasks rather than replacing creative work
