4K Blu-ray Player VS Amazon Prime Video... Pros vs Cons
I was looking at one of my favorite movies today (I mean, looking at the technical specs on the Prime Video page), and it says it's a 4K HDR movie. But knowing that streaming videos are compressed, I take it this means the movie on Amazon isn't really a genuine 4K... it's "4K" and is presumably lower quality than the same 4K movie watched on a 4K HDR blu-ray player... right?

And if so, how much better do you think a 4K movie is watched on the blu-ray player vs compressed video "4K" streaming from a site like Amazon?

I take it watching a "4K" movie streamed from Amazon vs watching it on a blu-ray player is similar to the difference between playing one of our favorite modern video games at 4K vs playing that same game at 4K while running DLSS at ultra performance or something, right?

So even though Amazon labeled the movie "4K" ... it's compressed video with upscaling or something like that kinda like DLSS, and thus not a genuine 4K...?

And perhaps more importantly, I heard somewhere the colors in streamed movies aren't as good as colors from a 4K blu-ray disk.

How much difference do you think it makes?

Assume the viewer in all of these scenarios has a 4K OLED monitor to view the game/movie on.

Everything is compressed. It It has little connection to resolution. What you may look after is the size of the compressed data and the method used. As some encodings are way better at the same rate. You have to look up actual numbers.

Your comment backs up the forum consensus. The comments in your link say it's like 10 to 15 mbps for streaming and like 30-50 or something for blu-ray.

Comparing the data in the movie might not account for compression/AI-upscaling magic though. I mean most people seem to say a 4K game played with DLSS looks pretty good, but the image you "started" with was much lower than 4K resolution. I'm guessing Amazon Video is similar, yes? It's probably like DLSS magic... making lower resolution images into higher resolution ones so even with a low bitrate the stream still looks like its pretty similar to 4K.

Every video is compressed yes, but the difference in quality between remuxed 4k video and random online video even if 4k might as well be considered compressed vs lossless. A lot of people make this mistake even thinking why can they shrink music so much but not blurays and their logic is flawed. The 4k disc is that good especially when you. An enable filters you like during playback where you wouldn't do that with an onine video.

The difference in IQ is pretty small, but the audio quality difference is pretty significant (take my opinion with a grain of salt).

Honestly, if you alr have bluray player, the correct choice is to always go physical.

Not sure what you mean by 'random online video', the torrents have everything in all sizes including 24G dumps in company of 6G, 2G, 1G versions. With variety of resolutions and codecs.

Back to OT, let's look at hardware. BD has 50G material for the 2h movie. Do I have bandwith to match that? Yeah, for several years. And it's not the top on ISP offer. So a provider could stream it to me. Even if network was a blocker, STBs with storage are around for a decade. And you could pre-DL the thing you plan to watch in the evening. with 2T SSDs going meinstream storage is hardy a problem.

So, technically APV could match and top BD. The question whether it wants to. On that I have doubts. They do pay for bandwidth so have to balance. And the mass of the regular audience is not enthusiasts. My experience with people is sour: back in crt/dvd days you had to set the aspect ratio. I saw many many to watch the content at wrong setting never bothering to push the f-ng button to make it correct. Having that ignorance do you expect them tell difference between true 2000p 1400p 1000p 700p and their watered down versions? I'd bet it's cheaper to ignore the small pool who can. And those may still sign up for other reasons.

On the other hand, buying BD disks? I have 500+ DVDs in the other room. I mean real, legal ones. And uncounted burns. How many did I watch in last 10 years? Almost none. I have a BD player for a decade, and still at 0, zero, nada disks. I f someone offered to gift me one, I'd have hard time to pick. And then would likely pick some I like but would not get to watch again.

Good movies are all but extinct. I used to consistently have over 100 cinema visits every year. And like over 80%. With just 2-3 considered outright bad. Now down to 2-3. And struggle to like even 1 of those.

I wish the real problem was choosing between the delivery methods. Sorry for the rant.

Exactly why I buy 4K disks, I'm set up with an Atmos 7.1.4 system and since you're never sure that the bluray movie will have Atmos track like the 4K always have. Streaming almost never does.
Personally I think it should be more obvious on the sleeve that it has a Atmos audio track. We pay good money to have 4K resolution and even more to have Atmos sound so it should be

Jeff Bezo's Enterprise is an awful company that expropriates the name of a region that produces its own art, music, film, loads of literature, not to mention all kinds of handcrafts.

If the United States was any good at regulations (see how they've allowed mergers like Activision | Blizzard and now are very slowly talking about inviting Microsoft for a hearing for buying the gaming giant), they'd be forced to change names already. Maybe it even fits US's purpose of domination of America.

Very ironicly and very sadly, the sustainable production of Amazon is being shunned by the tech monster that destroys the environment and worker's rights like no other.

You can't reasonabily await for a magic sollution to Climate Change and massive inequity while funding such unethical businesses.

In the end of the day, you are buying single-serving DRM'ed bad quality content from bandits.

It's way more ethical to seed generously and foment community than to finance a bald oligarch alien.

The biggest problem with the 4K blu-ray disk route is the need to buy the 4K blu-ray player. $170 just to watch like maybe 6 movies... not sure its worth it. I don't usually like movies... just want the original 6 Star Wars.

With streaming you don't pay for anything but the movies themselves.

They are expensive. Reasonable price to me is maybe $100 bucks or around there but they are much higher.

Weren't blu-ray disk drives (not stand alone ones, but PC ones) like $80 or so many years back? Have they gone up, or are you referring to standalone ones and were they always more expensive? I was pretty sure the premium status/pricing should have come down over two full console generations later.

I think overall we've long reached the point where resolution is considered good enough (for now at least), so growth has slowed down, meaning what is now the high end stays high end longer, and retains high end prices as a result. 8K exists but I don't see it becoming a real thing too soon.

Normally I'd say this isn't a problem because you can just stay with 1080p instead of 4K, but TVs themselves have long gone towards 4K so I get the appeal of having source material that takes advantage of/justifies it. But if not, 1080p "neatly" fits into 4K at least.

Half a dozen movies, if you care about them that much, is close to where I, personally, would probably just say okay and get the $170 player though. I'd at least consider it on the grounds it's there for other movies you might be on the fence about.

internal 4k bluray drives (or even external for that matter) run around that price now ($80 or so). The standalone 4k bluray players like for your tv in the living room are like $180 around there at the cheapest. Maybe you can find a deal where it'd be like $165 or something but still very high. I've had an internal 4k bluray bluray drive in my pc for a couple years now. I had a standlone 4k bluray player, but it crapped itself after about 5 years and maybe 30 actual uses. I don't feel like spending my money on that again (or at least yet). I'm still collecting blurays especially 4k bluray movies just to know I have the actual thing in my collection.

Edit: Nevermind about the price of internal bluray drives. Seems that $70 or around there is for regular bluray drives, 4k ones are more expensive. I could have sworn they were cheaper. I also could have sworn that's about what I paid for my 4k drive. But now I'm confused because I think I have the model LG WH16NS40 except on Amazon it doesn't say it's a 4k drive, which would make sense since I actually had to downgrade the firmware to read 4k discs where the one it shipped with removed the ability to do that (how surprising).

My PC can't use an internal blu-ray drive because, like a lot of modern computers, the PC case is just not designed to accommodate optical drives. If I was going to get something I connect to the computer, it would have to be an external blu-ray drive.

Or else forget about connecting to the PC and go with a standalone 4K blu-ray movie player (or maybe a PS5) that I can directly connect to my PC monitor after unplugging it from my PC whenever I want to watch a movie.

But $500 for a PS5 is hard to justify because as a guy who likes games like Star Wars: Knights of the Old Republic and Mass Effect, I don't really see anything like that on the PS5 console that I can't already buy on PC.

Resolution and compression are separate things. To be 4K it just has to have a resolution of 3840x2160 - it doesn't matter how compressed it is.

Not sure about a video rented or purchased on Amazon, but Prime Video 4K is rather compressed and arguably poorer to look at than a 1080p Blu-ray. Disney+ is noticeably better quality (even on a Fire Stick), and Apple is reportedly better quality too.

Also if the detail of the image is better with blu-ray players because they transfer data faster than streaming internet video, wouldn't the image detail potentially be FAR better yet if the movie companies just let users download the digital movie files to their PC SSDs to watch that way?
