started churning through the series 2 blake's 7 discs
was pleased that the episodes with audio commentary in this season actually use secondary audio tracks instead of having a second copy :D
(i can probably postprocess that shit in ffmpeg on the series 1 episodes if i get antsy)
there are 3 episodes in series 1 with audio commentaries, in 2 versions each
so i can save like 50 gigabytes by merging the commentary audio tracks as secondary tracks and discarding the extra copies of the video :P
anyway, no rush on that. should be straightforward fmpeggery when i get to it
trying makemkvcon's firmware dump before attempting to flash the drive firmware, and it's just hanging
apparently this is a problem for the linux version of makemkv that others have seen :(
will attempt to resolve...
forum recommended downgrading to a known-good version for the firmware flash: eg makemkv 1.17.7
this runs and claims to be successful but when i reboot i'm on the same firmware so it's not taking
i may have the wrong images :D
claims to be ripping Ghost in the Shell (1995) in Ultra-HD now :D \o/
movie itself is 54 gigs, plus a few gigs of special features which I assume are in HD, we'll see later
Ultra-HD discs ship with video in HEVC, so they'll benefit the least from a potential re-encoding to AV1 for space savings despite being the largest space-takers because they ship four times as many pixels as HD :D
For MPEG-2, VC-1 and H.264 discs I can get much more significant space savings if I decide to re-encode them, but I have to deinterlace any 480i, 576i, or 1080i material.
Interestingly a lot of Blu-rays these days ship lossless audio tracks which are also quite large!
3.1G Ghost in the Shell (1995) - DVD.mkv
21G Ghost in the Shell (1995) - HD.mkv
51G Ghost in the Shell (1995) - Ultra HD.mkv
ah, moore's law
score! Infuse on the AppleTV actually plays back the original HDR HEVC, even if I enable subtitles
looks nice. is it worth an extra 51 gigabytes of disk space? maybe :D
and now back in the Ultra HD mines... :D
another HD/UHD pair:
25G Pitch Perfect 3 (2017) HD.mkv
56G Pitch Perfect 3 (2017) Ultra HD.mkv
the HD disc has an H.264 8-bit SDR video track at about 26 Mbps average, plus several audio tracks and subtitles
the Ultra HD disc has an HEVC 10-bit HDR video track at about 74 Mbps average, plus the same audio and subtitles
my rough mappings for experimental AV1 transcodes:
2 Mbps for 480p/480i/576p/576i <- from ~5 Mbps MPEG-2 on DVDs
12 Mbps for 1080p/1080i <- from ~24 Mbps H.264 on Blu-rays
60 Mbps for 2160p HDR <- from ~75 Mbps HEVC on Blu-rays
(for interlaced sources I have to deinterlace))
However I'm not certain my current AppleTV groks AV1 in hardware, I'm going to have to do some test runs before I commit to anything.
And I'm not committed to re-encoding in the first place still, just fiddling around.
Dark City Director's cut Ultra HD disc has *eleven* audio tracks:
* 7.1ch Dolby TrueHD + Dolby Atmos
* 5.1ch ac3
* 5.1ch DTS-HD MA
* 5.1ch DTS
* stereo DTS
* stereo ac3
* 5x stereo ac3 audio commentary tracks
and one English SDH subtitle track
The Stuff (1985) - Theatrical release Ultra HD disc has three audio tracks:
* stereo 24-bit PCM
* 2x stereo ac3 (commentary)
Apparently you can straight up ship uncompressed PCM audio on Blu-ray and everybody considers this a fine use of bitrate. :) :P
found the secret to selecting which version of a title to play back in the Infuse front-end on Apple TV:
*long-press* the play/resume button on the title screen
then pick 'Select version' from there
it occurs to me there was a time when these 100Mbps Ultra HD Blu-ray streams would fill my entire network bandwidth <3
fuck yeah 2.5Gbps backbone in the apartment
Dark City 4k edition comes with both director's cut and theatrical cuts in Ultra HD 2160p/HDR
The Stuff 4k edition has the theatrical cut in Ultra HD 2160p/HDR and a prerelease cut in HD 1080p/SDR
Pitch Perfect 3 and Ghost in the Shell 4k editions ship the same cut in both Ultra HD 2160p/HDR and HD 1080p/SDR versions on separate discs.
no consistency :D it's the wild west here
the portable drive seems a lot pickier about discs than the internal drive
internal drive likes it fine \o/
i now has a complete archive of Max Headroom, both seasons (and they're short seasons for an American show of its time: 6 and 8 episodes respectively. what is this fucking britain?)
also done ripping The Starlost, which'll be fun
and working on Jeramiah season 1
still have to track down season 2 of that; I'm not 100% sure I saw the whole end of season 2 when it first came out
*watching Max Headroom ep1*
how did they get this project funded it explicitly shows the network executives as evil bastards :D
wait, Theora has a *car* in her bedroom?
how does she afford this apartment in the big city
the casting in this show is just great
Matt Frewer, Amanda Pays, Jeffrey Tambor... all just do *wonderful*
@loke hmm.... Wikipedia says the original UK pilot was on Channel 4 and the US series was developed for ABC, which is one of the big networks here, but it was produced in both cases by a smaller studio
probably gave them more leeway ;)
@brooke my Pirates of the Caribbean 1 MKV has one pcm_s16le English audio (4608 kb/s) and one ac3 (640 kb/s) ^^
(and I always switch to the second one because I think the voices are weirdly quiet on the first… though taking a closer look now, I think it might just be that little Elizabeth is too quiet compared to the music at the very beginning of the film, regardless of the track ^^)
@brooke wat
is the visual quality also better? ^^
@LucasWerkmeister eh looks good enough to my eye either way ;) no point trying to merge them, i'm just chucking the extra copy ;)
i bet it was background for a menu or something ridiculous
@brooke my Back to the Future 1 + 3 MKVs for some reason have the Japanese audio before the English track, which is always a fun surprise
I should just fix that with a quick ffmpeg tbh
