title: How to get resolution of app video preview for iPhone 6 (750 x 1334)?
body: <p>I've just created some app video previews for both the iPad and iPhone 6 Plus in iMovie and was able to export these videos to the needed sizes (900 x 1200 for iPad and 1080 x 1920 for iPhone 6 Plus). As a bonus, Apple allows us to use the 1080 x 1920 resolution for 4 inch devices. </p>
  
  <p>That only leaves the iPhone 6 which needs to be 750 x 1334. There is no option to export to this size in iMovie as I don't believe it's a standard size. </p>
  
  <p>I am wondering, how are people producing videos for this resolution?</p>
