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*

Max Headroom is a DVD release, seems to ship 480i; single stereo audio track, single subtitle track, no extras.

Nothing fancy, but it's got every episode of the US show and it seems like a clean enough transfer for a 1980s show! :D

This is gonna be fun to finish going through over the next few weeks. Haven't seen them since it came out in the 80s!

how u know when an episode is gonna fuck your shit up:

Babylon 5: "Written by J. Michael Straczynski"

Blake's 7: "Written by Terry Nation"

I still feel like in an ideal world this Blake's 7 Blu-ray set would've just shipped 576i50 data instead of upscaling to 1080i59.94

but whatever. my AppleTV would've just done the same upscaling realtime anyway

breakdown of space used by my show rips so far (movie rips are a smaller chunk of the total, in another folder)

HD shows that run multiple seasons take a *LOT* of space :D

short-run DVD series like Max Headroom feel almost like rounding errors lol

ok these rips make it *easy peasy lemon squeezy* to make screenshots with or without subtitles

just fire it up in vlc, set the subtitle track if appropriate, and hit 'snapshot'

(for HDR i have to do a further post-processing step to tone-map to SDR, but most of my Ultra HD HDR discs have an HD SDR companion disc which I've also ripped)

wait you're telling me it wasn't officially confirmed ivanova was gay until they hook up later?

after seeing her in this outfit in the first episode?

4k transfer of The Stuff mostly just lets you see the film grain in incredible detail :D

(squashed back to SDR from HDR with my hdrfix tool, then attached here which might downscale it from 2160p)

Doing some testing in the background with re-encoding, if i decide to go ahead with that.

Possible targets:
* AV1 for best compression, or
* HEVC for better support on my AppleTV

Ultra HD Blu-ray discs are already in HEVC, and while they're big I only have a few of them for movies.

The biggest chunk of library size is TV shows on H.264 HD Blu-rays: Babylon 5, Blake's 7, Orphan Black

DVDs feel tiny in comparison but would get a big compression uplift from replacing the ancient MPEG-2.

My suspicion is that Infuse on the AppleTV will try to decode AV1 in software and it will be ok for SD and maybe HD but likely too slow for Ultra HD.

Which leaves a possible compromise target of leaving Ultra HD discs in HEVC and re-encoding everything else to AV1 for space. ;)

I'll test playback later after work when my test encodings are done.

did a quick playback test:

* AV1 at 480p23.976, 480p59.94, 1080p23.976, and 1080p59.94 8-bit SDR plays back fine on the Apple TV (4K 2nd generation)

* AV1 at 2160p23.976 10-bit HDR is.... way too slow on the same device; super choppy playback

So I'm inclined to either the all-HEVC model or the hybrid AV1-for-SD-and-HD / untouched-HEVC-for-Ultra-HD model if transcode the collection.

Will do more encoding and space estimation tests after work :D

DVD set shipped and arriving March 3:

Dinotopia (TV miniseries)

yes, i'm finding all the good stuff out there

rough estimate using these hypothetical AV1-vs-whatever compression ratios per input codec:

mpeg2video: 60% savings
h264, vc1: 40% savings
hevc: don't recompress

run over the entire collection extrapolates:

total duration: 647.2 hours
total input bytes: 4278.9 GB
total output: 2520.6 GB
space savings: 41.1%

HD h264 content dominates; UHD hevc content is higher bitrate but have few of them; DVD mpeg2 is horrible bitrate but low resolution.

i'm not sure that's enough capacity increase to make it feel worth it, but if i add enough HD and UHD discs to the collection it'll eventually outstrip my current drive's space :D

meaning recompression or buy bigger drives ($$$$)

here's a breakdown by input codec:

mpeg2video - SD DVDs
total duration: 379.2 hours
total input bytes: 970.2 GB
~2.6 GB/hour

vc1 - One (1) HD Blu-ray
total duration: 2.0 hours
total input bytes: 20.6 GB
~10.3 GB/hour

h264 - Babyon 5 and Blake's 7 together make up half of this lol - most HD Blu-rays
total duration: 255.4 hours
total input bytes: 2919.7 GB
~11.4 GB/hour

hevc - Ultra HD Blu-ray
total duration: 10.7 hours
total input bytes: 368.4 GB
~34.4 GB/hour

*looking more carefully at Babylon 5: The Gathering and In The Beginning DVDs*

ohshit

all the exterior effects shots are 29.97 fps progressive?

and all the interior film shots are 24/23.976 fps telecined to 59.94 interlaced :D

so if that's consistent through the series, that means all my 23.976fps Blu-ray discs are cheating me out of 20% of the spaceship special effects frames ;)

deinterlacing the 480i59.94 materials with yadif=1 preserves every frame but introduces some artifacts

Ripping the DVD set of the Babylon 5 spin-off Crusade, which never quite found its stride

"I'm not Bruce Boxleitner, but..."

from the 4K Dogma (1999)

(snapshotted in VLC to .png then tone-mapped to SDR with my hdrfix tool and saved as .jpg)
