In accordance with new features found on the latest iPhones and iPads, Apple has updated the
iOS version of iMovie to support 4K video, as well as 3D Touch and other new gestures that are part of that technology. The new version supports iOS 9, and includes other features that aren't exclusive to the newly-announced iPhone 6s line and iPad Pro. Among these is support for working with 1080p video at 60 frames per second, a redesigned Audio browser, and compatibility with Slide Over and Split View in iOS 9.
The 3D Touch and 4K editing support are limited to the new iPhone 6s line and the iPad Pro. The new iPhones are the first capable of shooting in Ultra HD, while the iPad Pro is able to work with up to three 4K streams, offers a new full-height Media browser, keyboard shortcuts specific to the new iPad Pro Smart Keyboard, and even a pixel-accurate 1080p HD viewer.
The app also takes advantage of 3D Touch on devices that have it, for example allowing users to start new video projects directly from the home screen by pressing deeply on the iMovie icon to bring up a contextual menu. Users on all devices now have some other new features, such as the option to hide the Media Browser while editing, the option to disable the "Ken Burns Effect" animation on photos, a redesigned Project Details view that allows previews of projects without opening them, and improved Inspector controls, among other more general improvements.
The update also adds support for a new Video view, as well as adding Canadian French, Hindi, and Traditional Chinese (Hong Kong) to the list of included languages. The update is free for existing users, and costs $5 for new users from the App Store.
