App Previews look simple—a 15–30 second clip on your product page—but App Store Connect only accepts a fixed set of accepted resolutions. Apple notes that most previews come from screen recordings, so you export to the accepted size for that display class, not necessarily the phone’s native pixel grid.
We already cover storytelling and “should you bother with video?” in the preview design guide and the video vs screenshots framework. This article is the spec sheet: numbers from Apple’s App preview specifications.
| Rule | Spec |
|---|---|
| Length | 15–30 seconds |
| Count | Up to 3 previews per device size and localization |
| File size | ≤ 500 MB each |
| Frame rate | Up to 30 fps |
| Codecs | H.264 (.mov, .m4v, .mp4) or ProRes 422 HQ (.mov only) |
| H.264 bitrate (guidance) | About 10–12 Mbps, progressive, up to High Profile Level 4.0 |
| Audio | Stereo; AAC ~256 kbps at 44.1 / 48 kHz (PCM allowed with ProRes) |
| Default poster frame | Around second 5 (changeable in Connect) |
| Processing | Up to about 24 hours after upload |
| iMessage apps | Previews not available |
Orientation: portrait or landscape for iPhone/iPad; landscape only for Mac, Apple TV, and Vision Pro. Previews appear before screenshots on the product page. If the preview aspect ratio differs from your screenshots, it may show in “A Closer Look”.
For modern Face ID / Dynamic Island phones, portrait uploads converge on:
| Display class | Portrait accepted | Landscape accepted |
|---|---|---|
| iPhone Duo | 886 × 1920 | 1920 × 886 |
| Dynamic Island (large), including Air / Pro Max / Plus | 886 × 1920 | 1920 × 886 |
| Face ID (large) | 886 × 1920 | 1920 × 886 |
| Dynamic Island (medium) | 886 × 1920 | 1920 × 886 |
| Face ID (medium), including 16e / 17e | 886 × 1920 | 1920 × 886 |
| Home Button (large) | 1080 × 1920 | 1920 × 1080 |
| Home Button (medium) | 750 × 1334 | 1334 × 750 |
Duo’s device resolutions (for example ~2034 × 1398 / 2853 × 2007) are not the preview export sizes. Do not ship a 1398 × 2034 screenshot canvas as a preview file.
| Platform | Portrait | Landscape | Notes |
|---|---|---|---|
| iPad 13″ / 12.9″ / 11″ / 10.5″ classes | 1200 × 1600 | 1600 × 1200 | 9.7″ also lists 900 × 1200 / 1200 × 900 |
| Mac | — | 1920 × 1080 | Landscape only |
| Apple TV | — | 1920 × 1080 | Landscape only |
| Apple Vision Pro | — | 3840 × 2160 | Landscape only |
If UI is consistent, supply the highest required size and let Connect scale down; upload per-size sets only when you need different compositions.
From Apple’s App Previews page:
ffprobe.Static canvases can be drafted in a screenshot editor such as AppShot Maker, then edited into a preview—but always re-check Apple’s table before you upload.
Can I upload a native 2796×1290 screen recording as-is?
Usually no. Scale to the accepted size for that class (886 × 1920 portrait for most modern iPhones).
Are previews required?
No. Screenshots are. See the required screenshots / iPad FAQ.
Does Google Play use the same file upload?
No. Play uses a YouTube URL—see the Play promo video guide.
