Explains how immersive vs spatial video encode, the actual codecs and metadata needed, and where current specs diverge: MV-HEVC magic enables intra‑view prediction and yields 30–50% bitrate savings vs dual H.265 streams, APMP introduces per‑camera distortion boxes and a Apple projection media profile with VR180/WFOV options, and AAV ships fisheye stereo frames plus proprietary embedded camera‑distortion blobs and HDR‑only workflows — practical tradeoffs, tool support, and where pipelines currently break.
