Perceptual Quality Assessment of Spatial Videos on Apple Vision Pro

Immersive stereoscopic (3D) video experiences have entered a new era with the advent of smartphones capable of capturing stereoscopic videos, advanced video codecs optimized for multiview content, and Head Mounted Displays (HMDs) that natively support stereoscopic video playback. In particular, Apple's recent introduction of spatial video capture on the recent iPhone Pro series and immersive playback on the Apple Vision Pro (AVP) has accelerated the mainstream adoption of stereoscopic content. In this work, we evaluate the quality of spatial videos encoded using optimized x265 software implementations of Multiview HEVC (MV-HEVC) on the AVP and compare them with their corresponding 2D versions through a subjective test.
