Quest Now Natively Supports Spatial Video Originally Meant for Vision Pro
Apple's feature of playing back spatial videos captured on the iPhone 15 has been overshadowed by Meta's announcement that Quest now natively supports the MV-HVEC video codec. Meta has confirmed that users will be able to upload and playback spatial videos from the iPhone 15 Pro and iPhone 15 Max on their Quest headset. This new feature allows users to experience their memories and media content in a whole new way. For more details, visit the source at Road to VR.
