Find out the encoding settings of an original blu-ray as in this case.

From what I see in a thread on this forum,

https://forum.makemkv.com/forum/viewtopic.php?style=11&t=22183

it is possible to find out the encoding settings that were used to encode an original blu-ray, something I was unaware of.

Arrow blu-ray disc of the movie "Donnie Darko"

Encoding settings:

cabac=1 / ref=4 / deblock=0:-1:-1 / analyse=0x3:0x133 / me=umh / subme=10 / psy=1 / psy_rd=1.00:0.15 / mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-3 / threads=12 / lookahead_threads=2 / sliced_threads=0 / slices=4 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=1 / constrained_intra=0 / bframes=3 / b_pyramid=1 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=1 / weightp=1 / keyint=24 / keyint_min=1 / scenecut=40 / intra_refresh=0 / rc_lookahead=24 / rc=abr / mbtree=0 / bitrate=35000 / ratetol=1.0 / qcomp=0.10 / qpmin=0 / qpmax=69 / qpstep=4 / vbv_maxrate=38000 / vbv_bufsize=28500 / nal_hrd=vbr / ip_ratio=1.40 / pb_ratio=1.30 / aq=1:0.50

Are the encoding settings only visible on some original blu-ray discs and not on others? if so, why?

If with Mediainfo it is not always possible to view the encoding settings, with what other software would it be possible?

Only if the settings are added to the bitstream as x264 does by default.
Other professional blu-ray encoders do not have this implemented.
x264 is only used for a selection of Blu-rays, so one can not expect to see parameter listings in all cases.

Thanks.

So, for example, if they use a software like Handbrake, would those settings be visible?

I suppose Handbrake is not a professional blu-ray encoder. I would like to know the name of the ones used in the professional blu-ray encoding world, if anyone knows.

Thanks a lot.

How many hours (approximately) could it take to re-encode that same blu-ray with the same encoding settings with software like that?
