I am trying to make a video for App Preview in Apple App Store. I created video using QuickTime Player, making a screencast of simulator. After doing this i imported this video to iMovie and performed some changes. I now want to export this video for App Store, but iMovie doesn't offer the resolution of 640x1136 for shared video as a file.
I exported in highest resolution and imported in QuickTime Player again. QuickTime Player has option to export video for iPhone 5, iPAd 2 etc. So i tried that, but the resolution stays the same only file format has changed.
How can i create 640x1136 resolution video that is created in iMovie or are there some alternatives?
SOLUTION:
Thanks, i ended with camtasia. I exported HD imovie video file to camtasia and cropped the video to desired resolution. Export worked!

Don't forget the iPad 3rd Generation has an on-screen 'Home' button.You'll need another preview for it, even though the resolution is the same as the 2nd generation. If you've used 'safe areas' in your screen designs to avoid the button, your app may appear differently on the two devices. Apple's latest spec does suggest they're not accepting one as an alternative for the other. See: https://help.apple.com/app-store-connect/#/dev4e413fcb8
