Why do some movies take so long to convert from HD to 4K?

Are you referring to any specific software and machine being used? That depends widely on both factors, as well as the method of upscaling it (such as using AI or a more simple method). More information may be helpful in answering your question.
I've used Topaz Labs Video Enhance AI, which can use either a CPU or a graphics card. A dedicated graphics card is much faster, though it still takes quite a while. From what I've seen, the size of the source image seems to be one of the biggest factors in the upscale time. And it seems just the process of using AI to recognize the image and fill in details takes time. I don't know enough about it to give more information.

You know, I once heard that if you had well preserved master films in 25mm, those still beat modern digital recordings (even films from the 1920s) and benefit when upgraded from mpeg 4 to an HD capable format.

That's part of the problem. Also (not as often), sometimes streaming services can be unavailabl
due to high traffic or other problems, or sometimes your internet service might go down.
In a way, relying on streaming services for everything seems like relying on over-the-air
broadcasts. You have to wait for something to become available, and then as you said, it can be
taken away later. I always thought that's one of the reasons they started producing movies & TV
shows that people could buy and own. Now, it seems many people are content with relying on
streaming services for the things they want to watch.

30 years ago it made sense to own _that_ special movie you wanted in VHS, because there weren't so many TV channels providing quality films and shows in an abundant way. Nowadays, if _that_ film is not available, you are bound to find three hundred to substitute it at no cost (or close).
There is no specific reason to own your own copy of things because their value has gone under, unless you are a hardcore like me and want to reduce your dependence on content providers.

If you want to watch a particular movie, I don't think anything else can substitute for it. You could choose another movie to watch, but it won't be the one you originally wanted to watch..

They've done that with many movies for the transitions from VHS to
DVD, then to 1080p blu-ray, etc.. It does seem like it has taken
longer to remaster some movies to 4K though.

think that has officially even been released on 1080p yet (though
I'm not sure).

it seems to be the total opposite of the premium music services where
your initial buy in gets you pretty much every album ever made

I like to own them so that I can watch them when I want - without
worrying about them being romoved from the streaming service and
put in some imaginary "vault" or having them removed entirely
because some group is offended by the content of a movie that was
released in a different time, to a different generation. Yeah, I just
want to make sure I can always watch my movies when I want. :-)\
if the film they want to watch is not there, they will watch
something else without breaking a sweat in the least.

I got a beta version after they added newer Radeon support, but ironically the main thing I wanted to upscale (Babylon 5) was already done by HBO/Warner.
Some of the tests I've seen are really good, but to do a proper production, every 2-4s clip would need to be cut, processed with
multiple options, the best one chosen manually and re-stitched for the final output for commercial redistribution. Other than some of the Star Wars despecialized edition type projects, I don't know of any
independent efforts nearly to that scale. Would be cool to see more though. I don't think I could handle that kind of work though... seeing the same clip 5-10 times and picking the best one, over and over and
over again.
I think TM was probably just referring to getting a 4K release of existing HD material.
Or, like more recent examples retroactively declared "insensitive" and censored/removed from online availability altogether. Not that I really want to watch some of the censored films, but can see why some might
want to.

of license reasons. The developpers bought a license for selling the soundtracks for X years, and once the license expired, they removed the music from your game.
This does not happen with MS-DOS games.
I'm a newbie at all of this, but noticed that my 4K Roku TV doesn't support h.265 encoded video, only h.264. I have to be careful what I try to play on it.

with some looking better than others. I still think it doesn't

promising, but I think it still has a ways to go.

For me, this is the big reason why I want my media store locally.
With a DRM-loaded pseudorental (known as streaming) you only get to
access the content as long as the provider has a license to lend it
to you, or as long as it decides.
I have been told some steam games have lost their soundtracks
because of license reasons. The developpers bought a license for
selling the soundtracks for X years, and once the license expired,
they removed the music from your game.

I'll watch movies I've seen 10 times just to avoid commericial
interuptions. I only watch the local news and then it's all netflix
for me. I never saw any value in making copies of movies. The movies
that are worth making copies of always show up one way or another
onlin or on air these days. Then there's the torrents too. ;-)

ugh no way. it doesn't turn blurry, it ends up with those swirly
patterns. it's significantly more distracting imo.

That was the story behind the 70's TV show "WKRP in Cincinnati". It had some amazing music from the time, albeit playing in the background and not an integral part of the show. The clearances and the cost for the music was prohibitive, apparently since it had to be negotiated/cleared song by song.
Except for one episode that had Elton John's "Tiny Dancer" as a tie-in to
the plot. They couldn't get the rights to the song and re-dubbed it into the show. Now it sounds more like "Hold me closer, Tony Danza".

Yeah. I've sat down to a movie night, realized the movie we wanted
to see was $19.99 to rent, then asked my wife to go make some
popcorn, and we'll watch the movie in 10-20 minutes. :)

Is it the TV itself, or is it the app you use that doesn't support h.265?
Yeah, music licensing is particularly bad... The Wonder Years was a
prime example of how bad it gets, since it was mixed into the master, they were largely blocked from online and disc based media for years.
better/faster in the next generation or two... Radeon and NVidia cards are so much faster, but the quality/size worse than CPU, I still choose CPU encodes, just takes forever... I'll sometimes have days worth of encodes queued up that would be a couple hours with hardware.
I go through similar about once a month... sometimes I'll just pay the $4-7 rental price to not deal with the hassle, but at $15+ for a 20yo movie, I'd rather just download it.
Most of what I'm up for ripping myself is stuff that I cannot get in higher definition anyway, or otherwise is unavailable in torrents. I do buy some things because I want to support certain actions, and money talks, even if mine is a drop in the bucket.
Likely a lack of hardware decoding on chip... when 4k streaming devices first came out, h.265 was still really new and a lot of chips on those devices didn't have hardware decoders (and they're all too slow for software decoding). For those things, if you have a desktop/server online, best to setup a plex server.

Weird.. if you have a desktop or server that's always on, may be worth setting up a plex server that can transcode to h264 for you... this way you can still store in the smaller (size wise) format.

mins. What causes this? Bad disk?

i paid for the movie "Water World" on dvd because nobody had ripped it at the time (at least that i could find. it was a long long time ago. it's NOT a wildly popular movie by any stretch lol).
nowadays even hot garbage is fairly easy to find with a handful of seeders.

Yeah, I have a Plex server at home. I had one TV that seemed to
have trouble with h.265 even through the Plex app, but another TV
where h.265 seemed to play without any problems.
Not sure... I've had issues with a couple disks here and there, likely
an error that may not show up on a real BR player. I have bought AnyDVD
HD as well as MakeMKV usually one or the other, I can get a clean rip to
my HD.
Will usually then re-encode with Handbrake using mkv container and
h.265, if the original audio isn't too big, I'll leave it as-is, or recompress to 64kbps per channel aac.

I am not a media expert, but some DVDs employ obscure
features as to make it harder for desktop software to
support it.
For example, Disney DVDs have the chapters stored in a
scrambled order, so if you rip the DVD straight ahead or
play it directly you won't get to watch the movie properly.
Which is yet another reason not to purchase a Disney product.

A while ago, I bought the Lifetime Pass for Plex when it was on sale.
I read one of the features of Plex Pass is that it can make use of a
GPU for transcoding. My BBS/Plex PC is using the Intel graphics on
the CPU, and I've thought of buying an inexpensive GPU for it so it
can transcode easier. But currently my only TV now can play h.265, so
it hasn't been a problem.
At the same time, I wondered why they don't implement h.265 decoding
in the Plex player app. I thought smart TVs these days would
generally have a processor fast enough to decode even that video
codec, but maybe not.

I wonder how that works. I know DVDs have copy protection, but anything that i
capable of playing a DVD (including a PC with a DVD drive and compatible softw
re) should be able to at least play it. I haven't had a DVD that I was unable >o play in a PC.
There's software that can rip a DVD, even with copy protection. I heard DVD co
y protection was cracked fairly soon. I've been able to rip any of my DVDs usi
g DVD Shrink (which makes ISOs of DVDs, and can either shrink it to a 4.7GB DVD
R or keep it full-size for a 9.4GB DVD-R). There's a lot of other ripping soft
are that can rip it to a video file too.
I am guessing that Duma's set is BluRay? Maybe the BluRay spec
can be manipulated like that.
Yeah, most Integrated SOCs have a dedicated processing for media decoding, if they don't usually not powerful enough.
That is an interesting reversal. I always thought that and PC's

Likely a DRM scheme that abuses standards for how tracks are laid out or something similar that manifests on PC players/rippers but not actual hardware... would be surprised if AnyDVD and MakeMKV don't have it circumvented.
