So, I have on my collection several movies that I like to make a backup and last weeks I was thinking about encode that backup to MKV 265 10 bit (I check and Bd rebuilder cant do that I´m wrong?)

Let me explain, for example I have Star Wars , last days I make a backup with Rebuilder

So, when the BD25 was finish, just for see whats happens I tried to encode this BD25 to MKV 265 10 bit with another program and make me a file around 15gb comparing with the almost 22gb of BD25?

This MKV file with 15gb is a perfect copy of my BD25

So I wonder if I keep this MKV file as backup and some time when I need it if I just restored this MKV again to a BD25 I´ll get the same quality that I previously get when I encode the first time?

For example the DTS audio I encode to AAC

Jdobbs I hope dont be Broking any rules, if I do, just let me know dear please I dont any bad intention

Thank you in advance!!

ps: I can´t find in Bd rebuilder this option

First of all, you should keep the original Blu-Ray disc in a safe place. This is your master for all subsequent re-encodes.
Secondly, as every re-encode of a re-encode (like your MKV 265 10 bit) introduces new losses and artefacts (they might be small though), it is not recommended to keep a re-encode of a re-encode as a master or archival copy.
