How to make an App Preview video
An App Preview is the short video on your App Store product page. It autoplays, usually muted, so it has to work without sound and show the core action in the first seconds.
The specs to hit
- Duration: 15–30 seconds (outside that window, App Store Connect rejects the upload).
- Up to 3 preview videos per device size, per locale.
- Format: .mov, .mp4 or .m4v; H.264 or ProRes 422 HQ; frame rate up to 30 fps; max 500 MB.
- Audio: a stereo track is required, even if the video is watched muted.
- Resolution: match the target device's accepted size — do not assume one size fits every iPhone. Always re-check the current App Store Connect specification before export.
- Content: real footage of your app in use, not a brand commercial.
A workflow that fits in an afternoon
- Pick one core action — the thing a new user should understand in five seconds.
- Record that action on your iPhone, then trim it to 15–30 seconds.
- Frame it: put the recording inside an animated mockup so the product page reads as a finished promo, not a raw screen capture.
- Check it muted, on a phone-sized screen, before you upload.
