For example, the iPhone 16 Pro Max records at 1320×2868, but App Store Connect requires 886×1920 for the iPhone 6.9-inch slot. A full table of accepted resolutions is provided for iPhone, iPad, Mac, Apple TV, and Apple Vision Pro slots. The fix is scaling and cropping the recording to the exact target resolution using an ffmpeg command (scale then crop to avoid distortion or black bars), or using a paid Mac app built by the author, App Preview Converter, which automates resolution conversion plus frame rate, duration, audio track, and codec fixes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does App Store Connect reject my app preview video even though it matches my device's screen resolution? App Store Connect requires an exact pixel resolution for each device slot, and no device actually records video at those exact sizes. For instance, an iPhone 16 Pro Max records at 1320×2868, but the iPhone 6.9-inch preview slot requires exactly 886×1920, so a raw screen recording will always fail no matter which device it was captured on. _Developers troubleshooting App Store Connect rejections can find fixes and version-specific gotchas on daily.dev._ ### What resolution does App Store Connect require for an iPhone 6.9-inch app preview video? App Store Connect requires exactly 886×1920 for portrait or 1920×886 for landscape in the iPhone 6.1-6.9 inch device slot. Other slots include 1080×1920 for iPhone 5.5 inch, 750×1334 for iPhone 4.7 inch, 1200×1600 for iPad 11-13 inch, 900×1200 for iPad 9.7 inch, and 1920×1080 for Mac and Apple TV. _Anyone shipping iOS app previews can track resolution requirements like these on daily.dev._ ### How do I convert a screen recording to the exact resolution App Store Connect requires without distorting it? Use ffmpeg to scale the video to fill the target resolution while preserving aspect ratio, then crop the overflow so the output matches exactly: ffmpeg -i input.mov -vf "scale=886:1920:force_original_aspect_ratio=increase,crop=886:1920" -c:v libx264 -preset slow -crf 18 -r 30 -c:a aac -ar 48000 output.mp4. Scaling alone either distorts the video or adds black bars, both of which can trigger rejection. _Developers automating App Store submission workflows can find practical ffmpeg fixes like this on daily.dev._ ## Similar posts on daily.dev - [How to fix "The frame rate of your app video preview is too high" error](https://daily.dev/posts/how-to-fix-the-frame-rate-of-your-app-video-preview-is-too-high-error-8piggfctk) · Sarunw · 0 upvotes · 0 comments - [How to fix app preview video that is too long or too short](https://daily.dev/posts/how-to-fix-app-preview-video-that-is-too-long-or-too-short-6evubygmj) · Sarunw · 0 upvotes · 0 comments - [How to fix app preview stuck on "Processing" in App Store Connect](https://daily.dev/posts/how-to-fix-app-preview-stuck-on-processing-in-app-store-connect-eeqsnfgau) · Sarunw · 0 upvotes · 0 comments - [Recording a Physical iPhone for App Preview Videos](https://daily.dev/posts/recording-a-physical-iphone-for-app-preview-videos-wuwiokhaz) · SwiftLee · 0 upvotes · 0 comments --- Tags: [#backend](https://daily.dev/tags/backend), [#ios](https://daily.dev/tags/ios) [View this post on daily.dev](https://daily.dev/posts/how-to-fix-app-preview-wrong-resolution-error-in-app-store-connect-rkn4abrnh) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"How to fix app preview wrong resolution error in App Store Connect","url":"https://daily.dev/posts/how-to-fix-app-preview-wrong-resolution-error-in-app-store-connect-rkn4abrnh","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-to-fix-app-preview-wrong-resolution-error-in-app-store-connect-rkn4abrnh"},"datePublished":"2026-08-25T07:42:20.064Z","dateModified":"2026-08-26T04:00:11.645Z","description":"App Store Connect rejects app preview videos unless they match exact pixel resolutions per device slot, since no device actually records at those exact sizes....","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/8e62076e34cbc099c3d5a36324541299?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/8e62076e34cbc099c3d5a36324541299?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Sarunw","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Person","name":"Sarun Wongpatcharapakorn","url":"https://daily.dev/sarunw","image":"https://avatars.githubusercontent.com/u/795368?v=4","interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"EndorseAction"},"userInteractionCount":20}},"commentCount":0,"discussionUrl":"https://daily.dev/posts/how-to-fix-app-preview-wrong-resolution-error-in-app-store-connect-rkn4abrnh","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"backend,ios","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sarunw","item":"https://daily.dev/sources/sarunw"},{"@type":"ListItem","position":3,"name":"How to fix app preview wrong resolution error in App Store Connect"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/how-to-fix-app-preview-wrong-resolution-error-in-app-store-connect-rkn4abrnh#faq","mainEntity":[{"@type":"Question","name":"Why does App Store Connect reject my app preview video even though it matches my device's screen resolution?","acceptedAnswer":{"@type":"Answer","text":"App Store Connect requires an exact pixel resolution for each device slot, and no device actually records video at those exact sizes.
