To optimize video in iOS, particularly for spatial experiences, Apple has introduced several enhancements and techniques:
-
Video Stabilization: For smoother video, especially important on larger screens like those in visionOS, you can set the preferred video stabilization mode to "cinematic extended enhanced." This mode uses a longer look-ahead window and crops more of the frame to achieve smoother results. This is particularly useful for spatial video capture on devices like the iPhone 15 Pro.
-
Spatial Video Capture: On the iPhone 15 Pro, spatial video is enabled by positioning the wide and ultra-wide cameras side by side, allowing for a horizontal baseline similar to human eyes. This setup is crucial for capturing spatial video, and the API for this is now public, allowing developers to record spatial video with minimal changes to their existing code.
-
AVPlayer View Controller: For presenting video, the AVPlayer view controller can be sized to match the frame of the window scene to make content fullscreen. However, for full spatial presentation, using a preview application is recommended to avoid depth conflicts and keep the UI uncluttered.
These optimizations are part of the broader effort to enhance video experiences on iOS and visionOS, leveraging the capabilities of the latest hardware and software improvements.
For more detailed information, you can refer to the session Build compelling spatial photo and video experiences (07:00) which covers these topics extensively.
