OpenMontage（GitHub：https://github.com/calesthio/OpenMontage ，2026-03-29 创建，今晨抓取时已 76,536★）自称是第一个开源的 Agent 视频制作系统：12 条制作管线、100 多个工具、700 多个 Agent 技能与制作知识文件，目标是把你的 AI 编码助手变成一间完整的视频制作工作室。

用法是一句话说需求，Agent 接手调研、写脚本、生成素材、剪辑与最终合成；也可以从一个你喜欢的参考视频出发，Agent 先分析它的文案、节奏、分镜与风格，再给出 2–3 个差异化方案、诚实的工具路径、成本预估与小样，确认后才全量制作。配套的 Backlot 是本地实时看板：制作进行到哪一步、每个素材的成本与质量分、每次供应商选择的分项打分与决策记录都在墙上，素材生成还会在分镜联络表上暂停等你逐场审批，而不是渲完才发现不对。零 API Key 也能用：免费真实素材纪录片路径（从免费素材库与开放档案里找真实动态片段、剪成时间线、渲出成片）就是为此准备的；需要生成式供应商时，README 也会先报成本——示例里 60 秒动画短片 1.33 美元、50 秒竖屏成片约 4 美元——并有预算控制。支持 Claude Code、Cursor、Copilot、Windsurf、Codex 等助手。AGPL-3.0 开源。

为什么值得了解

• 做短视频、产品片、讲解视频的人最缺的不是模型，而是“制作流程”：脚本、分镜、素材、配音、字幕、合成、质检每一步都要有人管；OpenMontage 把这套流程做成了 Agent 能直接走的管线
• “先报成本、逐场审批、决策留痕”这三条对所有 Agent 制作类工具都值得借鉴：花钱之前先知道花多少，渲之前先看小样，事后还能查每一步为什么选这个供应商
• 零 Key 的真实素材路径对不想绑卡、不想被按量计费的人很友好：先用免费路径跑通一条成片，再决定要不要为生成式素材付费

OpenMontage (GitHub: https://github.com/calesthio/OpenMontage , created 2026-03-29, 76,536 stars at this morning’s fetch) calls itself the first open-source, agentic video production system: 12 production pipelines, 100+ tools and 700+ agent skill and production-knowledge files, aimed at turning your AI coding assistant into a full video production studio.

You describe what you want in plain language and the agent takes over research, scripting, asset generation, editing and final composition; or you can start from a reference video you love, and the agent first analyses its transcript, pacing, scenes and style, then offers 2–3 differentiated concepts, an honest tool path, a cost estimate and a sample before full production. The companion Backlot is a local live board: which stage production has reached, each asset’s cost and quality score, and the scored, auditable record behind every provider choice are all on the wall, and asset generation pauses on a scene-by-scene contact sheet so you approve visuals before the render, not after it is too late. Zero API keys also works: a free real-footage documentary path (finding real motion clips from free stock libraries and open archives, cutting them into a timeline and rendering a finished piece) exists for exactly that; when generative providers are needed, the README quotes costs up front — a 60-second animated short at $1.33 and a 50-second vertical film at about $4 in its examples — with budget controls. It works with Claude Code, Cursor, Copilot, Windsurf, Codex and other assistants. AGPL-3.0 licensed.

Why it’s worth knowing

• For anyone making short videos, product films or explainers, what is usually missing is not a model but a “production process”: script, storyboard, assets, narration, subtitles, composition and quality checks each need managing; OpenMontage turns that process into pipelines an agent can walk directly
• “Quote the cost first, approve scene by scene, keep an audit trail of decisions” are three practices worth borrowing for every agent production tool: know what you will spend before spending it, see samples before rendering, and be able to trace afterwards why each provider was chosen
• The zero-key real-footage path is friendly to anyone who does not want to link a card or be metered: run one finished piece through the free path first, then decide whether generative assets are worth paying for
