Help with MKV 4k 10 Bit Rips

[graffight]

Started ripping my 4k collection to put onto a 4tb hard drive using dvdfab.

I'm converting to HEVC MKV 4k 10 bit but I'm not sure what size I should be aiming for.

i'm not too fussed about the sound , because I tend to watch most of them with my headphones on anyway.

I'm watching them on a 65" OLED.

I've started aiming for around 15gb which means once the files complete its going to be around 19-20gb

And the quality is spot on, so much so i'm thinking could I squeeze it down a bit more

I know it may depend on the length of the movie, has anyone got any size guides?

Hi, you can move the slider to change the output file size, set the value between 0.1~0.15 and it should be able to output a file in a smaller size with ok quality.
