Hithub BluDisc — 4K UHD Music Video Collection Blu-ray

The Hithub BluDisc 4K UHD Music Video Collection Blu-ray presents the definitive home release of a music artist’s complete music video catalogue in 4K Ultra High Definition video at 3840 by 2160 pixel resolution with High Dynamic Range in Dolby Vision HDR10+ dual-track encoding, alongside Dolby Atmos audio mixes of each video track that expand the stereo mixes to a full three-dimensional audio object field. The video content is authored on a 100-gigabyte dual-layer UHD Blu-ray disc capable of the 128-megabit-per-second peak data rate required for 4K video at the HEVC codec profile specified by the UHD Blu-ray format specification, sustaining a maximum video bitrate of 108 megabits per second for the most motion-complex sequences while maintaining Dolby Atmos audio at 768 kilobits per second on the TrueHD audio track. Dolby Vision metadata encodes per-scene and per-frame HDR tone-mapping parameters that instruct the display hardware how to accurately render each frame’s peak luminance and color saturation within the display’s own gamut and luminance range, whether that display achieves 500 nits or 4,000 nits peak brightness. The packaging uses the Premium UHD Blu-ray case format with a magnetic flap closure, housing the disc in a tray that positions it label-side up, preventing disc surface contact with the case spine. A 32-page booklet details production notes for each video.
