GitHub - calesthio/OpenMontage: World's first open-source, agentic video production system. 12 pipelines, 52 tools, 500+ agent skills. Turn your AI coding assistant into a full video production studio

OpenMontage is an open-source, agentic video production system that turns AI coding assistants (Claude Code, Cursor, Copilot, Windsurf, Codex) into full video production studios. It offers 12 production pipelines (animated explainers, documentary montages, cinematic trailers, talking heads, etc.), 52 tools, and 500+ agent skills. The system supports both free/local workflows using Piper TTS, FFmpeg, Remotion, and open stock footage from Archive.org/NASA/Wikimedia, as well as paid cloud providers (FLUX, Kling, Runway, ElevenLabs, Suno). Key features include reference-video-driven creation, live web research before scripting, scored provider selection across 7 dimensions, budget governance with cost estimation, and production-grade quality gates including pre-compose validation and post-render self-review. Videos can be produced for as little as $0.15 using AI-generated images animated via Remotion, or up to ~$3 for full motion-video productions.
