Video compressor

This article by Simon Willison describes how he created a video compression tool using the WebAssembly build of FFMPEG. He recorded a short demo video of his Equal Earth animation on his phone and needed an optimized version for his blog. Using Claude Fable 5.1 in Claude Code, he built a web-based tool that runs FFMPEG in the browser, allowing efficient video compression without server-side processing. The post includes technical details and links to related tags like ffmpeg, webassembly, and claude-code.
