These details come from Apple's App Store Connect documentation as of November 2026. Apple's own warning is worth repeating: use the accepted resolution in that documentation, not the device's screen resolution.
The basic rules
- Length: 15 to 30 seconds.
- Count: up to 3 previews per device size and language.
- File size: up to 500 MB.
- Frame rate: up to 30 fps.
- Poster frame: the 5-second mark by default, and you can change it.
- Processing: up to 24 hours after upload.
Format and encoding
There are two options:
- H.264 in a .mov, .m4v or .mp4 file, targeting 10–12 Mbps. Audio in stereo, 256 kbps AAC, 44.1 or 48 kHz.
- ProRes 422 HQ in a .mov file, with PCM or 256 kbps AAC audio.
A silent preview is fine, but if there's an audio track it has to be stereo and every track has to be enabled. We've seen previews rejected for mono audio, so check that before you export.
Accepted iPhone sizes
- iPhones with Dynamic Island (large and medium), Face ID iPhones (large and medium) and iPhone Duo: 886 × 1920 portrait, 1920 × 886 landscape.
- Home button iPhone, large (5.5-inch): 1080 × 1920.
- Home button iPhone, medium (4.7-inch): 750 × 1334.
So one video at 886 × 1920 covers almost every iPhone in use today. If a size is missing, the App Store scales the preview from the nearest size.
iPad, Mac and the rest
- iPad 13-inch, 11-inch and 10.5-inch: 1200 × 1600 portrait, 1600 × 1200 landscape.
- iPad 9.7-inch: 900 × 1200.
- Mac and Apple TV: landscape only, 1920 × 1080.
- Apple Vision Pro: landscape only, 3840 × 2160.
How to put a good preview together
Apple wants footage captured from the app itself, and showing things the app can't do is a reason for rejection. Most of the video should be screen recording. That doesn't rule out a device mockup, but the balance matters.
The order we use:
- First 3 seconds: the strongest feature. In search results the preview plays muted, and most people scroll on after a few seconds.
- The middle 15–20 seconds: two or three flows, each a short scene that shows one thing. Short captions on screen are fine.
- The last few seconds: a calm ending on the app's main screen.
The poster frame matters too, because it's what people see before anything plays. Don't let it land on a loading screen.
Recording the screen
Record in the Xcode simulator or on a real device, with a clean status bar: 9:41, full battery, no notifications. Remember to bring the recording down to 30 fps. iPhones record at 60 or 120, and the App Store won't accept that.
Drag the recording into Mockup Center and it plays on the device's screen. When you export, set the frame to 886 × 1920 and the frame rate to 30. Templates suited to previews are collected on the app preview video page.
