Apple today announced that the App Store can now display app previews — short videos demonstrating an application’s capability — in listings for tvOS apps for the latest version of the Apple TV.

An app preview can help Apple TV users better understand the utility of an app and thereby feel more compelled to download it, as Apple pointed out in a blog post.

These videos are available in the App Store for iOS apps, but it had never existed for Apple TV. Now that’s changing.

How simple is it to make one of these videos for tvOS? All app developers have to do is connect a Mac to an Apple TV running the tvOS operating system and then record the app with QuickTime in landscape mode after selecting the Apple TV as the recording device.

The App Store for Mac OS X still does not support these app previews.

More detail on making these videos is here.
