OpenMontage
Reaching #1 on GitHub Trending with over 48,000 stars, OpenMontage is the first open-source agentic video production system — transforming AI coding assistants like Claude Code, Cursor, Copilot, Windsurf, and Codex into complete video studios that handle research, scripting, scene planning, asset generation, editing, and final rendering through natural language prompts. Twelve production pipelines cover animated explainers, cinematic trailers, documentary montages, talking heads, screen demos, podcast repurposing, character animation, localization and dubbing, avatar spokesperson videos, hybrid productions, clip factory batch processing, and animation workflows. Over 100 registered Python tools connect to 60+ providers including Kling, Runway Gen-4, Google Veo 3.1, FLUX, Google Imagen 4, ElevenLabs, and Suno AI for cloud generation, plus Piper TTS, WAN 2.1, Hunyuan, and CogVideo for fully local GPU rendering — while free footage from Archive.org, NASA, Wikimedia Commons, Pexels, and Unsplash powers the documentary montage pipeline's CLIP-indexed retrieval system for real-motion video without paid generation APIs. Two composition engines — Remotion for React-based programmatic video and HyperFrames for HTML/GSAP motion graphics — render final output with spring animations, word-level captions, kinetic typography, and SVG character rigs. A seven-dimension scored provider selector, pre-compose validation gates, post-render ffprobe self-review, slideshow risk scoring, configurable budget caps with per-action approval thresholds, and the Backlot live web dashboard for visual production monitoring enforce production-grade quality at every stage. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
Benefits
- Complete Zero-Cost Video Production
- Produce finished videos without any paid API keys using offline Piper TTS narration, Remotion composition, FFmpeg encoding, and free archival footage from Archive.org, NASA, and Wikimedia Commons.
- 60+ Providers with Scored Selection
- A seven-dimension scoring engine evaluates every provider across task fit, output quality, control, reliability, cost, latency, and continuity — automatically selecting the optimal tool with a full decision audit trail.
- Real-Footage Documentary Without Generation
- The documentary montage pipeline builds a CLIP-indexed semantic corpus from open archives and stock sources, retrieves actual motion clips by narrative slot, and cuts them into finished video essays.
- Production-Grade Quality Enforcement
- Pre-compose validation blocks broken plans, post-render self-review runs ffprobe and frame sampling, slideshow risk scoring prevents static renders, and human approval gates pause at every creative decision point.
Features
- 12 Production Pipelines
- End-to-end workflows for animated explainers, cinematic trailers, documentary montages, talking heads, screen demos, podcast repurposing, character animation, and localization.
- Dual Rendering Engines
- Remotion delivers React-based programmatic video with spring animations and word-level captions, while HyperFrames renders HTML/GSAP motion graphics and SVG character rigs.
- Backlot Live Dashboard
- Browser-based production monitoring board shows pipeline stages, storyboard contact sheets, creative approval gates, cost tracking, and full production replay with scrubbing.
- Reference-Driven Creation
- Paste a YouTube video, Short, Reel, or TikTok and the agent analyzes transcript, pacing, scenes, and style to produce differentiated production concepts with cost estimates.
- Budget Governance System
- Pre-execution cost estimation, spend caps with configurable modes, per-action approval thresholds at $0.50 default, and cumulative decision audit logging prevent surprise bills.
- Agent-Agnostic Architecture
- Compatible with Claude Code, Cursor, Copilot, Windsurf, and Codex through shared YAML manifests and Markdown skill files — no proprietary orchestrator or vendor lock-in.
