BDRemux is a more explicit release-name form of Blu-ray Remux. It belongs to the broader Remux family rather than being a separate quality tier above or below Remux. Disc video, audio and subtitle streams are usually preserved and placed in a playback-friendly container. Still check 2160p, HDR, audio and size: the BDRemux label alone does not guarantee UHD, HDR or a particular lossless track.
