Claude Video Skill · sulemank137 bundle Build a short HD product film two ways: cut one from an existing screen recording with ffmpeg, or — when no usable recording exists — compose it frame by frame from offscreen captures of the real UI (Qt, web/Electron, or any X11 window) plus real camera footage. Covers auditing footage for dynamic moments, aspect-correct crops and push-ins, animated lower thirds, crossfades, light and dark cuts from one compositor, side-by-sides synced at cut time, metric charts that draw themselves, GL/3D window capture over X11, and a numeric check that a captured UI panel is animating rather than flickering. Use when asked to make a promo/teaser/demo video, cut a highlight reel, film a product "without screen capture", or fix pacing, zoom, aspect-ratio, caption or flickering-UI problems in an edit.
