 "title": "Render one video in wide and tall sizes at once",
 "page_title": "How to render one video in wide and tall sizes at once with Explainroo",
 "summary": "Make one project into a YouTube video and a TikTok or Reels version in one step.",
 "who": "A creator who posts the same explainer to YouTube, Shorts, TikTok and Instagram and wants each size without re-editing.",
 "problem": "Each platform needs a different frame size, and reformatting a finished video by hand loses captions and timing.",
 "outcome": "Separate renders of one project in wide, tall and square sizes, each with word-by-word captions where the size supports them.",
 "steps": [
  "Set up Explainroo with `npm install` and `node bin/explainroo.js doctor --fetch` inside the repo folder",
  "Render the wide version and the tall version with `explainroo render videos/demo --size tiktok`",
  "Add `\"watermark\": false` to video.json only if you have a reason to remove the corner watermark",
  "Check small text for a phone screen with `explainroo check videos/  --view-width 854`",
  "Upload the MP4 with the .srt or .vtt subtitle file and the chapters the render writes"
 ],
 "agent_prompt": "In the explainroo repo at <repo folder>, render the project at videos/<project> in the wide size and the tiktok size. Expected output: two MP4 files next to each other. Verify that the tall version keeps your text clear of the platform buttons before you upload.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The README says the watermark helps other people find Explainroo, and removing it with \"watermark\": false is up to you.",
