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.

I'm talking about movies in general here.

probably just having to clean and inspect almost every frame of the film, sc with a higher resolution (= slower) scanner, fix color, etc. luckily film quality is usually quite nice and using a modern scanner can get that much more data.

I venture to say he means movies in general. "Why are they taking so long to release my favourite movie in 4k?"

Personally, I still sometimes like to buy movies to own.
I'm still waiting for a high-def release of The Abyss. I don't think
that has officially even been released on 1080p yet (though I'm not

i've already had plenty of occasions where this or that movie that i randomly think of is not on any of the streaming sites. or is behind a premium hbo/starz/etc paywall. or have made it half way through a show only to find out i only have a month to finish because it's going offline.
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..
Now I know who to contact with my ripping questions. I
recently purchased an external DVD r+w and made a few
copies for a friend. One of the copies crapped out a 23
mins. What causes this? Bad disk?
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.
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.
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.
mp4 is a container format, often h.264 aka AVC for 1080p or lower for video. 4K is still mp4 as the container format but h.265 aka HEVC for the encoding. HEVC has a better, imho, rendering degradation when over-compressed (blurry vs blocky).
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.
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.
that isn't the use case they intended for those cards.. they're
great for live streaming.. but i duno why video editing software
likes to default to using them.. :/
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.
Now I know who to contact with my ripping questions. I recently

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.
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 recently bought a DVD set that says that it is "made for
DVD players andmay not play on PC drives." As advertised,
I am not able to watch, or rip, that one except watching on
a DVD player (an XBOX).

That is an interesting reversal. I always thought that and PC's
DVD player could do anything. What is this "set" that you

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.

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.
