OpenMontage by Calesthio
Open-source system that turns an AI coding assistant into a video production studio: you describe the video in plain language and the agent researches, writes the script, generates or gathers assets (including free stock footage and open archives), edits a timeline and renders the result, showing a contact sheet with per-asset cost before the final render. The project lists 12 production pipelines, 100+ tools and 700+ skill and production-knowledge files.

How fresh these numbers are
