A short preview video can lift conversion meaningfully — it shows your app in motion in a way static screenshots can't. Here's how to make one that actually helps.
Keep it short Aim for 15–30 seconds. Apple caps previews at 30 seconds and most viewers drop off well before that. Show your best three moments and stop.
Hook in the first three seconds The opening frames decide whether anyone keeps watching. Lead with your core value in action — the "aha" moment — not a logo animation or a splash screen.
Show the real product Preview videos should feature genuine app UI, not abstract marketing footage. Users want to see what they'll actually get. Move through a real flow at a natural pace.
Design for sound off Most people watch with the sound muted. Add short on-screen captions so your story lands without audio, and never rely on a voiceover to carry the message.
Match your screenshots Use the same device frames, colors, and headline style as your screenshots so the whole listing feels cohesive. The video is the motion version of your first screenshot.
Export the right sizes Both stores have specific resolution and aspect-ratio requirements per device. Export the correct format so the upload isn't rejected.
MoonStart's video studio turns your screens into an animated promo — Ken Burns pans, zooms, and transitions — with a live preview, then exports the video ready for your listing. Free.
