Apple has released a free app for managing your immersive (VR) video library, the Apple Immersive Video Utility. It is available in the App Store for both macOS and visionOS. The app has system requirements: M1 chip and macOS Sequoia.
Apple Immersive Videos are 8K 3D videos with a 180-degree field of view and spatial audio. The Weeknd and Metallica recently released their concerts in this format.
Apple Immersive Video Utility allows you to import, organize, package, and view Apple Immersive Video files on your Mac. Apple also says that there is a possibility of synchronized playback for viewing videos on multiple Vision Pro devices.
It looks like the program is primarily intended for immersive video directors, but for now anyone can download it.
