video-spec-builder vs VideoAgent
A director-skill for Claude Code/Codex: interrogates your vague video idea until it's a second-by-second storyboard spec (video-spec.md), ready for HyperFrames to render. — versus — All-in-one agentic framework for video: understanding and summarization, clip editing, and generative remaking, driven end-to-end through natural-language conversation.
Two philosophies for idea→video: video-spec-builder forces a human-approved storyboard spec before any rendering; VideoAgent owns the whole pipeline conversationally. Spec-first control vs all-in-one convenience.

video-spec-builder — the curator's take
Built on a sharp observation: the hard part of making a video isn't rendering, it's knowing what you want. Install the skill, say 'I want to make a video', and it grills you like a director — audience, length, the one takeaway line, which shot carries the weight — until a precise spec exists. The spec-first discipline is the value even if you never render. NOT a renderer (it hands off to HyperFrames) and the project's home base is Chinese-language — English docs work but the community and examples skew zh.
VideoAgent — the curator's take
From HKUDS (the lab behind LightRAG): describe what you want — 'summarize this lecture', 'cut the highlights', 'remake this as a trailer' — and the agent plans tool use across understanding, editing and generation in one conversational loop. The breadth is the differentiator; nothing else open-source covers understand+edit+remake together. NOT a video model itself — it orchestrates underlying multi-modal models, so quality and cost track what you plug in; young codebase from an academic group, expect research-grade edges rather than product polish.
