Loss of quality uhd

[sphere3923]

Hi, noob here.
When you rip a 4K Blu-ray using MakeMKV with a flashed uhd friendly drive and play it on a 4K device, will it truly be the original 4K quality from the UHD Blu-ray? Is there any loss of quality ?
Thank you for your time.

MakeMKV copies the video data from the UHD directly. What you get is what is on the disk. What you do afterwards may change quality, but the MKV generated by MakeMKV will have the exact video present on the disk.

There are audio options that can change things, but "stock" MakeMKV will copy the audio without change as well.

Subtitles will generally create two tracks per on-disk track. One will have "all subtitles", the created one will have "just those subtitles that have the FORCED flag set." Most often, the second will be discarded as empty.

Thank you for enlightening me !
