Show HN: Egaki – create videos with code and MDX files

- Egaki is a new open-source tool (by developer Yusuke Mori) that lets you create videos programmatically by writing code and MDX files — a blend of Markdown and JSX — instead of using traditional video-editing software. - MDX is an extension of Markdown that allows you to embed interactive JSX (React) components inside documents, commonly used in documentation sites like Docusaurus or Next.js blogs. - The project was posted on Hacker News as a "Show HN" — a community self-promotion format on the tech news aggregator Hacker News (run by Y Combinator's venture fund), where founders and developers share their side projects and startups for feedback. - This fits a growing trend of "programmatic video" tools (e.g., Motion Canvas, Remotion) that treat video as code, enabling version control, automation, and precise, reproducible edits — appealing to developers who find GUI-based editors cumbersome.
