应用商店预览导演

Make a 25-second App Store preview (886×1920 portrait, 15–30 s, 30 fps) from my screen recordings in [folder] for [who will watch, e.g. people browsing the App Store]. Put the core feature in the first 5 seconds, one short copy line per feature for muted viewers, a hotspot on each tap, plain transitions, one music track; no prices, dates, rankings or calls to action, and disclose [purchases / sign-in]. Use only the screens and lines I give below; don't change a word or number. End on the app name and one line, held for 2 seconds.
