The App Preview Video That Actually Converts

Not financial advice. Verify claims independently.

App Store preview videos are the most misunderstood creative asset:

What works:

  • First frame is the poster — users see a still before autoplay; it must stand alone
  • 15 seconds, not 30 — attention drops hard after that
  • Screen recording with UI callouts > motion graphics trailer
  • Muted-first — 80% watch without sound; text overlays carry the story

What kills:

  • App-store-generic music and swooshes
  • Intro/logo screens burning 5 seconds
  • UI captured on the wrong device (aspect mismatches look broken)

Stock Picks's preview is 14 seconds of a real trade being placed on paper — no trailer, no voiceover. It converts.
