I have not tested much, but you could rip JP/EN language and 720p/1080p/2160p movies aswell to get a bit better ratio.
I simply have no time atm to test deeper.
Edit: Sorry I used wrong command line syntax. I just realized this now lol.
Use this
Code:
xtool:d1:mue5,k0xB2407C45EA7C528738A94C0A25EA8F419DE4377628EB30C0AE6A80DD9A9F3EF0:mmermaid:mkraken:core_2.9.5
