So why would you want to remux a Blu-ray disc instead of simply ripping it to a digital format? There are several reasons:
Streaming services compress video to around 15–25 megabits per second (Mbps). A 4K Blu-ray runs at 60–120 Mbps. A Remux captures that full bitrate.
This takes the Remux and compresses it using codecs like x264 or x265. You can reduce a 60GB Remux down to 10GB. However, you lose fine detail, grain, and color accuracy. Dark scenes often look "blocky" or "banded."
