I vibe-coded this cli tool because most screen recording tools (with crop, zoom, effects etc) are GUI-based and my coding agent doesn't have any way of interacting with them. With it I was able to recreate all of the screenshots and recordings for the website of my Mac app, Grasmere (https://grasmere.app) in an hour or so.
