iOS App Preview videos - are all 3 iPhone resolutions required I've just completed an App Preview video for my forthcoming universal iOS app. I did it by capturing an iPhone 6 using QuickTime then editing in iMovie. 

If I only submit my iPhone 6 App Preview video (750x1334), will iPhone 5/5s and 6 Plus users be able to see the video on the App Store?

Or do I have to create and upload separate iPhone 5/5s &amp; iPhone 6 Plus videos?

Thanks.
In the end I only uploaded 3 videos - iPhone 5 resolution, iPhone 6 resolution and iPad resolution. When I visited the app on the App Store on an iPhone 6 PLUS - the iPhone 6 video was shown.

So it looks like larger iPhones will fallback to smaller videos if the larger preview video is not present. Presumably the iPhone 6 will fallback to the iPhone 5 video as well.
