This is the standard format for Ultra HD Blu-ray discs. It features a base layer (usually 4K HDR10) and an Enhancement Layer (EL) with dynamic metadata. It utilizes a dual-track or dual-layer system.
Understanding how these two Dolby Vision profiles handle video streams explains why this conversion has become so critical for home theater enthusiasts: Dolby Vision Profile 7 Dolby Vision Profile 8.1 4K Ultra HD Blu-ray physical media.
