App Store app preview video specs: size, length, format and poster frame
Apple's app preview is a short video on your product page. Apple sets its size, length, frame rate, file type and audio. This guide lists them for iPhone and iPad. Everything below comes from Apple's own pages, read on 12 November 2026. Apple changes these pages, so check the links before you upload.
The short version
- Length: 15 to 30 seconds.
- Frame rate: 30 frames per second at most.
- File size: 500 MB at most.
- Format: H.264 (.mov, .m4v or .mp4) or ProRes 422 HQ (.mov).
- Audio: stereo.
- Number: up to three previews for each device size and language.
- A preview is optional.
Resolution
Apple says to use these sizes, not your device's screen size. Sizes are in pixels, portrait then landscape.
| Device | Portrait | Landscape |
|---|---|---|
| iPhone with Face ID or Dynamic Island (large and medium) | 886 x 1920 | 1920 x 886 |
| iPhone Home Button 5.5-inch and 4-inch | 1080 x 1920 | 1920 x 1080 |
| iPhone Home Button 4.7-inch | 750 x 1334 | 1334 x 750 |
| iPad 13-inch, 12.9-inch (2nd generation), 11-inch, 10.5-inch | 1200 x 1600 | 1600 x 1200 |
| iPad 12.9-inch (2nd generation), also accepted | 900 x 1200 | 1200 x 900 |
| iPad 9.7-inch | 900 x 1200 | 1200 x 900 |
Apple's page says app previews are not supported on the 3.5-inch iPhone. The same page lists sizes for Mac, Apple TV and Apple Vision Pro, which this guide leaves out. An iOS preview can be portrait or landscape.
File format and audio
For H.264, Apple lists a target bit rate of 10 to 12 Mbps, progressive video, up to High Profile Level 4.0, and .mov, .m4v or .mp4 files. For ProRes 422, only the HQ version is accepted, in a .mov file at about 220 Mbps. Both are capped at 30 frames per second and 500 MB.
Audio is stereo. For H.264 that means AAC at 256 kbps and 44.1 or 48 kHz. For ProRes, Apple lists PCM or AAC at 256 kbps. Stereo can be one two-channel track or two one-channel tracks, and Apple says all tracks should be enabled.
Poster frame
The poster frame is the still image people see on your product page and while the app installs. Apple's default is the frame at 5 seconds. To pick another, open the preview in App Store Connect, hold the pointer over it, choose Edit Poster Frame, move to the frame you want, choose Set Poster Frame, then Done. Apple's page says poster frames can't be edited after assets have been approved, so choose before you submit.
How many, and what scales
You can add up to three previews for each device size and language. If your app looks the same across device sizes and languages, Apple says to provide only the highest resolution required and the smaller sizes scale down. You can still upload a separate preview for any other size. If a preview is missing for a language, Apple uses the next best available one. Apple says previews always show before screenshots on iPhone, iPad, Mac and Apple TV. Uploads can take up to 24 hours to process.
Before you upload
- Export your video at one of the sizes in the table above.
- Trim to between 15 and 30 seconds and export at 30 frames per second or less.
- Export H.264 with stereo AAC audio, 500 MB or less.
- In App Store Connect, open your app's version page and upload the preview for the device size and language.
- Set the poster frame, then check the preview plays from the first second.
Apple says previews must meet App Review Guidelines 2.3.3 and 2.3.4. Read both before you cut the video.
