调整所有设备的iOS App Preview的大小
[英]Resize iOS App Preview for all devices
问题描述
I am soooo close to submitting my app to the app store, but we have one problem. 
我非常接近将我的应用提交到应用商店，但是我们有一个问题。 App Previews. 应用预览。 You need 1 preview for EVERY device, and I'm sorry I don't have all your devices apple :( . Is there anyway to automatically resize my one app preview I have already without losing MAJOR quality? 每个设备都需要1个预览，很抱歉，我没有所有的设备apple :(。无论如何，是否可以自动调整我已经拥有的一个应用预览的大小而又不会失去主要质量？

The easiest way to do it, is to record an App Preview for the biggest screen size and then scale it down with tools like After Effects or Final Cut Pro. 最简单的方法是录制最大屏幕尺寸的App Preview，然后使用After Effects或Final Cut Pro等工具将其缩小。 I'm not 100% sure, if you can also do it with iMovie. 我不确定100％是否可以使用iMovie做到这一点。 If you're supporting iPad, you need to create another version for iPads. 如果您支持iPad，则需要为iPad创建另一个版本。
Here are the official sizes (Landscape only for simplification): 以下是官方尺寸 （仅为简化起见，请使用横向尺寸 ）：
5 Series: 1920 x 1080 (< Standard 1080p 16:9 aspect ratio) or 1136 x 640
iPhone 6: 1334 x 750 (~ 70% of 1080p)
iPhone 6 Plus: 1920 x 1080
AppleTV: 1920 x 1080
iPad: 1200 x 900 or 1600 x 1200 (4:3 aspect ratio)
I suggest you capture the material for the App Previews with an iPhone 6 Plus (real device or simulator if that works for you) and then scale it down for the best quality. 我建议您使用iPhone 6 Plus（适用于真实设备或模拟器）为App Preview捕获素材，然后按比例缩小以获得最佳质量。 If you don't have an iPhone 6 Plus, you can use an iPhone 6, but you will lose quality. 如果没有iPhone 6 Plus，则可以使用iPhone 6，但是这样会降低质量。
Summary: You only need 2 different App Previews - with regards to resolutions - if you are only supporting iPhones. 摘要：如果仅支持iPhone，则只需要2个不同的App Preview（关于分辨率）即可。 (3 if you are supporting iPads.) （如果支持iPad，则为3。）
