(Half Side-by-Side) originally released by the "PublicHD" group.

The "PublicHD" tag refers to the original release group responsible for the encode. During the early 2010s, this group was known for high-bitrate releases that prioritized over small file sizes. For a movie like Gravity , where fine details (like the texture of a visor or distant stars) are easily lost to "blocking" or "noise," the PublicHD encode became a gold standard for digital collectors. Summary of the Viewing Experience

Thus, PublicHD’s Half-SBS 1080p 3D encode remains the best option for home viewers who want both high fidelity and stereoscopy. The DTS audio (lossy but high bitrate) is still excellent, though an upgrade to DTS-HD MA or TrueHD would be welcome – but that would increase file size significantly.
