How to upload app video preview to ITunesConnect?
Maybe you have noticed latest feature on Apple's AppStore – Application video preview. It is very nice feature, enabling users to see applicaton in action without downloading/installing the app. But first, developer must prepare video with custom dimensions (e.g. for iPhone 6 it should be 1334 x 750 or 750 x 1334px). But that's not the only problem..
Apple requests latest OS & browser – yet unreleased: "To upload your app video preview, you must use Safari and OS X v10.10 or later"
But here is the simple solution… just go to Safari Develop > User Agent > Other …
end enter fake user agent string:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10) AppleWebKit/538.34.48 (KHTML, like Gecko) Version/8.0 Safari/538.35.8
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10) AppleWebKit/538.32 (KHTML, like Gecko) Version/7.1 Safari/538.4
And that should do the magic!
PS video should be very short! just 15 to 30sec.. read more here: App Previews – App Store – Apple Developer
