I built a Claude Code skill that turns an app's screens into a launch video. This is the Kerby launch it made. 40 seconds, Remotion, music generated in code. Took four rounds to get here. The first three told a player's story and kept coming back stale. Soft zooms, weak copy, music that didn't fit. For round four I pointed it at Raycast's launch films instead. One camera moving across real UI, push-ins that land on the beat, and the game's own Play button turning into the end card. Two rules did most of the work: 1. Capture the app at 2x. It records at 4K and won't zoom past a screen's real pixels, so every push-in stays sharp. 2. Use the product's own copy. "Hit the kerb." beats anything I could make up about the game.
