calesthio/OpenMontage
OpenMontage is the world's first open-source, agentic video production system designed to leverage AI coding assistants for comprehensive video content creation. It boasts 12 pipelines, 52 tools, and over 500 agent skills, enabling users to generate videos from plain language prompts. The system handles various stages of video production, including research, scripting, asset generation, editing, and final composition. Unlike tools that merely animate still images, OpenMontage can produce "real video" by sourcing actual motion clips from free stock footage and open archives, editing them into a timeline, and rendering a finished piece. The platform supports starting video production from a reference video (YouTube, TikTok, local clips), where an agent analyzes the transcript, pacing, scenes, keyframes, and style to generate differentiated concepts, tool paths, and cost estimates. It integrates with various AI coding assistants such as Claude Code, Cursor, and Copilot. OpenMontage automates tasks like web search for topic research, AI image generation, script writing and narration with voice direction, background music selection, word-level subtitle burning, and final video rendering. It includes a multi-point self-review system for quality assurance, encompassing ffprobe validation, frame sampling, audio level analysis, and subtitle checks. The system also audits provider selections across seven dimensions, ensuring transparency and control over creative decisions.
