The Ultimate Digital Copy: A Complete Guide to 4K Blu-ray Remux
Part 9: The Future – Will Remuxes Die?
With the rise of AV1 codecs and the death of physical media (Best Buy stopped selling BluRays; Netflix’s disc service is dead), the future of Remuxes is uncertain.
- Streaming is winning: Studios prefer you rent digital copies with DRM.
- AV1 promises 4K at 10 Mbps: If this becomes standard, the "Remux advantage" shrinks.
- However: Physical 4K discs are still being produced for blockbusters (Oppenheimer, Top Gun: Maverick). As long as discs exist, Remuxes will exist.
The 4K Remux is the last bastion of bitrate war. It is the cinephile’s rebellion against the "good enough" culture of streaming. bluray remux 4k

What is "4K" (UHD)?
"4K" refers to the resolution of the image, specifically 3840 x 2160 pixels. In the context of Blu-ray, this refers to Ultra HD Blu-ray discs. However, 4K resolution is only part of the equation. UHD discs also introduce High Dynamic Range (HDR)—usually HDR10, Dolby Vision, or HDR10+—which expands the contrast ratio and color palette, offering brighter highlights and deeper blacks than standard High Definition (1080p).

Part 5: The Great Dolby Vision Debate (Remux vs. Disc)
This is where the water gets muddy.
The 4K BluRay disc format supports Dolby Vision Profile 7 (FEL – Full Enhancement Layer). This is the highest quality Dolby Vision available, containing a 1080p enhancement layer that can literally "repair" a 12-bit image from a 10-bit base layer. Streaming is winning: Studios prefer you rent digital
The Problem: The MKV container (version 1) did not support Profile 7 FEL properly. When you remux a disc to MKV, you often lose the "FEL" part of Dolby Vision. You either:
- Keep only the HDR10 base layer (losing dynamic metadata).
- Convert to a "single-track" profile 8.1 (good, but not perfect).
The Current Status (2024-2025):
- MakeMKV (the standard remux tool) now supports basic Dolby Vision Profile 7 MEL (Minimum Enhancement Layer).
- FEL is still tricky. Only specific players (the Nvidia Shield Pro 2019 with a modded Exoplayer, or the Ugoos AM6B+ running CoreELEC) can play FEL correctly.
- Conclusion for 99% of users: If you play a DV Remux on an Apple TV 4K (using Infuse), you are getting Profile 5 or 8.1 conversion. It looks great. It is not disc-perfect. For true purists, you must play the physical disc or a BDMV folder.
