Back up

Post by Anametureenthisiast » Wed Mar 25, 2020 10:22 am

Hi All

I am beginning to back up my bluray disks fully and I thought I would reach out as to the option it give me, as I don't understand the benefits (or not) of ticking the box "decrypt video files".

The software seems to suggest either way the backup will need opening with MAKEMKV or is this not the case?

Are there any other advice/tips when backing up large bluray collections (apart from a lot of space!?)

Thanks all

If you do not remove the encryption during the backup, whatever you use to play the video has to have the decryption key for the disk.

This is not a problem if your intention is to then use MakeMKV to create MKV files, but most playback programs will need to have the encryption removed first.

so if I decrypt the files then any dvd movie player can play it like a normal disk (except in bluray quality ofc).

DVD players expect MPEG2 video, and BD content is usually h264, although there are disks out there that use a variant of VC-1, and UHD content is almost always h265.

VLC, Kodi, and more can play the unencrypted BD backup files. I haven't tried to do it with the Win10 movie player. The Win7 player could not, at least not with out special "codec packs".
