Blu-ray Release

Overview

Blu-ray Release refers to the distribution of films on Blu-ray Disc format, offering high-definition (up to 1080p) video and multi-channel audio. Introduced in the mid‑2000s, Blu-ray surpassed DVD in storage capacity and feature set.

Blu-ray discs hold 25 GB (single-layer) or 50 GB (dual-layer) of data, enabling uncompressed video codecs and lossless audio formats such as DTS‑HD Master Audio and Dolby TrueHD. It supports interactive menus, pop‑up features, and BD‑Live connectivity.

By the 2010s, Blu-ray became the standard for physical home media. The later introduction of 4K UHD Blu-ray in 2016 further enhanced picture quality, leveraging HEVC encoding and HDR support.
