Turns app screenshots into polished MP4 walkthrough videos using Remotion. You feed it a series of screenshots (from a folder, a running app, or a live URL), describe each screen with titles and callouts, and it generates a React-based video composition with fade/slide transitions, zoom effects, text overlays, and a progress bar. The skill scaffolds the entire Remotion project, handles timing calculations, and gives you a live preview before rendering. Honestly most useful when you need a repeatable demo video that you can tweak and re-render as your UI changes, rather than recording and editing manually every time. Works best if you already have screenshots in a logical sequence.
