## Guides
- [Video API for Composition: The Full Guide](https://cueframe.ai/guides/video-composition-api): What a video composition API is, how it differs from generation and streaming APIs, and how to render production-quality video from a structured edit.
- [Add Captions to Video with a Video Editing API](https://cueframe.ai/guides/add-captions-to-video-api): How to add captions to video with a video editing API — transcription, timing, styling, and content-aware placement that keeps text off the speaker's face.
- [Agentic AI Video Editing: Workflow & Tools](https://cueframe.ai/guides/agentic-video-editing): What agentic AI video editing is, the discover-author-validate-render-verify loop an AI agent runs, and the tool properties that make it actually work.
- [AI Video Editing: Face-Aware Smart Crop](https://cueframe.ai/guides/face-aware-smart-crop-video-api): How face-aware smart crop, an AI video editing feature, reframes 16:9 video to 9:16 by tracking the subject and speaker, not a blind center-crop.
- [AI Video Generation vs. Video Composition API](https://cueframe.ai/guides/ai-video-generation-vs-composition-api): AI video generation synthesizes new pixels from a prompt; a composition API assembles known inputs into a precise, repeatable edit — when to use each.
- [Build an Automated Video Creation Pipeline](https://cueframe.ai/guides/automated-video-creation-pipeline): Build an automated video creation pipeline that renders finished video with no human editor — ingest, perceive, author, validate, render, deliver.
- [Headless Video Rendering for AI Agents](https://cueframe.ai/guides/headless-video-rendering-for-ai-agents): What headless video rendering is, why AI agents and CI pipelines need it, and how a programmatic video API renders video server-side with no timeline UI.
- [JSON to Video: Render Video from a JSON Edit](https://cueframe.ai/guides/render-video-from-json): How to go from JSON to video with a composition API — the document model, literal vs. intent-and-derived timelines, and the author-validate-render loop.
- [MCP Video Tools for AI Agent Editing](https://cueframe.ai/guides/mcp-video-tools): What MCP video tools are and how an MCP video server lets an AI agent do video editing — discover, author, validate, and render — and what to look for.
- [Video API Pricing Models Explained](https://cueframe.ai/guides/video-api-pricing-models): The common ways video APIs charge — per render, per minute, per second of compute, usage-based credits, and tiers — and how to predict and control spend.
- [Video API vs. No-Code Video Tool](https://cueframe.ai/guides/video-api-vs-no-code-tool): When a no-code video tool beats a programmatic video API, when it stops scaling, and how to tell which one your workflow — human or agent — actually needs.
- [Video API vs. Video SDK: Which to Use](https://cueframe.ai/guides/video-api-vs-sdk): The difference between a hosted video API and a self-run video SDK — operational burden, scale, determinism, cost, and which fits AI agents best.
- [Video APIs for AI Agents: What to Look For](https://cueframe.ai/guides/video-api-for-ai-agents): What matters when the caller is an AI agent, not a human — discoverability, free validation, determinism, explainable errors, and content-awareness.
