Couple notes on this, because I simplified things for the purpose of the video and to not get even more confusing.
Bottom line is - BUY THE BLACK BOX THAT SAYS 4K HDR. Anything else isn’t “true 4K”, it’s just a 4K master downscale and compressed to fit on a Blu-ray Disc.
- A 100% uncompressed movie would be a monster file. Terabytes. But the 4K discs are much less compressed than Blu-ray.
- There are some differences between Blu-ray and 4K discs at a much deeper technical level. Beyond what most people need to know or care to know. So I didn’t dive deep there for the purpose of a simple explanation.
- 4K is H265 compression and Blu-ray is H264. It’s a different type of compression. Taking a 4K master goes from 8 million pixels to 2 million pixels. Basically compressing the pixels down/downscaling. To me, those are sort of interchangeable terms.
- 1080p Blu-ray players cannot read the larger disc types so that is why they can’t play 4K discs. And yes there are deeper technical differences as well.
- As far as I can tell, you can put a 4K file (if it’s small enough) on a Blu-ray disc. You’d still need a 4K player to play that back in 4K because a regular Blu-ray player won’t support it.
Hope that helps! I tried to keep it simple enough for anyone to understand, but if you want to take a deep dive there are much smarter people than myself who can really get into the nitty gritty details of the discs.
Films At Home I appreciate the time and effort you put into this topic brother!
Keeping it simple and providing inaccurate or incorrect descriptions are not the same thing, you can keep things at a novice level without confusing it more by using wrong language. You are conflating resolution and compression for one, hdr meta data isn't a significant increase in file size compared to other aspects of the fish for two, and others. Your comment doesn't really excuse lack of accuracy in the video for the sake of simplicity, especially when the point of the video is to educate.
About this "Buy the black box that says 4k HDR":
It doesn't just say "4k HDR" on the box. Sometimes there's an HDR sticker at the front, sometimes it mentions HDR only at the back, HDR can be HDR10, HDR10+, Dolby Visions or a combination of those three. Besides, even though most of the boxes are black, not all of them are. I've got one myself that's completely white with only the name of the movie in blue at the front.
If you want to be 100% sure you're buying a real 4k disc, just remember what the 4k UltraHD logo looks like and try to find it somewhere on the box. If it's somewhere at the front, back or spine of the box, it's a real 4k release. If you can't find the logo anywhere, it's just a regular Blu-ray.
Yes, it helped. Thanks.
Antimonkat HDR does increase data size. And I’m talking about downscaling - that to me is compression. You’re compressing the pixels included from 8 million to 2 million. You’re downscaling. How’s that different? Maybe it’s just me using what I think are interchangeable terms
Correction: 4K UHD encodes are still compressed. You state more than once that on 4K it’s uncompressed which is just not true. Uncompressed video is WAY larger then the 80 or 90 GB UHD encodes, H265 is just more efficient and compresses the same quality at a much smaller file size. Which is why 4K becomes possible at only twice the space as a maxed BD disc.
Exactly. Even 2K DCPs are larger than most 4K discs
he should say recompressed instead of uncompressed. Only original film footage will be uncompressed.
So even 4k is compressed? I wonder what it would take to get a pure uncompressed image what that would look like
@@aaronlewis6325 Not worth it, you wouldn't gain much. You'd need a massive IMAX screen with equipment costing 2.000.000 to spot a difference.
Aaron Lewis
You probably wouldn’t even be able see an improvement in picture quality, unless it was blown up REALLY big...like if the movie was projected onto the side of a huge building.
True Lies and The Abyss come on Cameron! I'm sure the filming of Avatar 12 halted filming due to covid it would have been a perfect time to look over the these movies for approval of a Blu-ray or 4k
True lies and the abyss would be a dream on bluray or 4k.
don't forget ALIENS on 4k
I don’t want Cameron anywhere near his older films. After what he did to T2 4k and the aliens blu ray? No thanks, let someone else do it. Also they were working on abyss but i think Disney axed it when they bought fox.
@@EchoWinters I am.not sure but I did hear he changed the color timing on Aliens blu ray.. which kind of takes some time getting used to. T2 on 4k was scrubbed of grain for the 3D release and supervised by Cameron himself in the attempt to make it look like a new film, perhaps he dosent like film grain. I guess the bonus is that there are no official 1080p's of True Lies and The Abyss so the 4k's with the added HDR will be the way to go anyhow. Fingers crossed he dosent apply any DNR. I personally like film to look like film, if it was shot on 35mm then I want the grain to give the image its depth, otherwise you get a processed washed out looking picture
It just blows my mind that true lies is not on Blu-ray at least or now 4K. That movie is top-notch!
I love your enthusiasm Jeff, you remind me of me back when I started collecting LaserDiscs and learning about movie restoration and video mastering.
I have to agree with some of the previous comments though, the explanation is a bit inaccurate...
1. You can't hpothetically put 4k Ultra video on a BluRay disc and play it back on a standard Bluray player, the 4K video isn't compatible with BluRay players due to incompatible: compression codec, video resolution, colour spectrum, etc.
2. While Arrow may have a 4K master of Robocop they can only decide to release it on 4k Ultra BluRay if the rights agreement they negotiated with MGM permits it, they may only have the rights to release it on Blu-Ray.
The simplest explanation is:
A movie that's been mastered in 4K on Bluray is simply a 4K master that's been downresed to 1080p for BluRay.
The studios have been using 'Mastered in 4K' on BluRay packaging as a marketing gimic, possibly trying to mislead consumers into believing they're getting a true 4K video presentation.
Assuming the same film source and the same mastering equipment are used, there would be very little difference between:
- a movie that's been downresed to 1080p from a 4k scan
Vs.
- a movie that's been scanned natively at 1080p
The main reason a Mastered in 4k BluRay looks better than a previous Mastered in 1080p BluRay is that the 4k master was created 5-10+ years after the 1080p master, using vastly improved mastering technology/techniques and they've probably maximized the movie's bitrate favoring image quality over supplemental features.
It's not a fair comparison.
Correction to your correction. Standard Blu-ray is 2K, not 1K. 4K is 4 times the resolution of 2K because twice as many pixels vertically and twice as many horizontally equals 4 times as many.
@@nacthenud thanks, I agree 1k was not the correct term, I've replaced all mentions of 1k with 1080p.
Right, differences in resolution are a completely separate issue than how much that resolution is compressed. A 4k jpeg file is going to look better than a 2k jpeg file with equal compressions.
The single most important difference between 4k and blu-ray is HDR, it's the HDR that makes the real difference
While HDR is a bigger difference 4k without it looks better than blu-ray
Also immersive audio.
@@Thecatdrums3 in my opinion not by that much, it's the HDR that makes the picture pop
@@Thecatdrums3 No, no. You must take into consideration size of display and seating distance when determining how much of a difference 4K makes from 1080p. If you're setting at distance from a 4K set where it is impossible for your eyes to make the extra resolution that 4K makes from 1080p, than it doesn't make a difference. However, HDR makes a difference no matter the size of the display and seating distance.
One small thing I would add is that 4K bluray encodes onto the disc with HEVC which is a slightly more efficient compression than the standard Bluray encoding with is AAV so technically the bluray and 4K bluray discs are different sizes and using different encoding formats too. Very complex topic but think you did a good job simplifying it for the majority of people (the rest probably knew it already anyway so 😂). Keep up the great work
Facts!!!
Man your videos are so thorough and helpful!! Small time collector only have about 30-40 films I really love but I am scoping out 4k TV's and more into the physical media aspect and you've helped me out so freaking much !!!
"A typical 4K master is 80-90GB." Um, no. The 4K master is the file on the servers at the studios, and it's literally terabytes of data for the single movie file. Yes, terabytes. Typically films are mastered in OpenEXR, DPX, or ProResXQ. The 80-90GB version is what you'll find on a consumer disc, and it's a compressed copy of the 4K film, NOT the master.
I thought the DCP typically uses JPEG.
That means digital really sucks at 4 to 8 gigs from a terabyte source. Physical is still better at a 100 gigs.
@@Crlarl Yes, DCP uses JPEG2000 but thats only for cinema release, they have to be transcoded from the studios master
@@LiamJCash Hello all.
How big is one film frame before its compressed?
4K Ultra HD Blu ray V 4K DCP hard to tell difference on small TV sizes like 55 or 65 inch.
A 4K restoration on 1080p blu-ray is 4K down-rezzed to 1080p--simple.
Or it’s also called Mastered in 4K. Just like my Ghostbusters Mastered in 4K standard Blu-ray. I think the mastered in 4K Ghostbusters looks better than the actual 4K UHD.
@@djsoulfilter I'm glad I'm not the only one who thinks that.
Yeah it's just about resolution.
I have the 2018 blu-ray of 2001: a space odyssey which is a 4k restoration and it looks really good but not as the 4k, because it was half the price! Great informative video Jeff!
The 4k disc version is superior in every way. If you absolutely cannot pay regular price, 4k discs do come down. I even bought some PIXAR 4k steelbooks for less than $10 a while back.
I keep debating if I want to upgrade because I have the Blu-ray version and it took me awhile to purchase. I love the movie but it's so damn long I just don't know if I'll watch it enough but eventually if I can get it for cheaper than the going price.
Even the true UHD 4k release of 2001 is a down conversation. It was remastered at 8k and compressed down to 4k for this release. Does look fantastic though.
@@dan_hitchman007no, alot movies in 2k. And, people complain about 4k looking dark and artificial..
@@ILoveTheAllCreator That's because some regular Blu-ray discs have over pumped brightness. You are supposed to watch movies in a darkened room with a calibrated display.
I was a little confused. And you cleared that up for me wonderfully. Thanks a lot man!
The need to put Robocop on 4K UHD blu ray, literally one of the greatest films ever made.
Kobiedog31 That’s a matter of opinion.
Lol
Really robocop one of the greatest films ever made. Lol. I am truly laughing out loud at that. Not even top 1000.
MGM may license it to Arrow or some other small label now doing 4k releases since their distribution deal with Fox/Disney has ended. Robocop (the original) already had a 4k restoration done a few years ago. It would just need an HDR grading pass and ... maybe???... a Dolby Atmos remix.
@@glyn420 stop drinking, booze got you already dude. Yes Robocop is one of the best movies ever made.
@@glyn420 It's one of the best action sci-fi films! If you don't like Robocop then you're not a very fun person to be around! Lol
For me picture quality improvement is now at a small incremental stage , 4k are undoubtedly better but a blue ray is still excellent- it’s the sound and the ways it’s been coded IE in Atmos that makes a big big difference for me when viewing home dvds . For the best enhancement on home movies one area I feel has made the best difference is to definitely look to invest in ACTUAL in ceiling speakers and a Sony str1080dn av receiver . Monitor audio do fantastic products to suit everyone’s needs
Technically all movies are compressed.
Downscaling from 4K to HD will reduce the file size on it's own and OFC you will loose resolution / detail
Also, I do not believe that a blu-ray player would be able to decode a 4K file, even if it was in the correct format
This was pretty enlightening for me in terms of how people were confused by this, because I had no idea people would find that confusing! Good explanation :)
what would it take to get lord of the rings extended editions on 4k lolol
Actually, they’re getting released later on this year.
The return of the king with its half a dozen neverending endings is probably closer to 1TB. ;0)
@@jonathanmendez6366 wait are you serious?
You’d need like five disks 😂
Original planned for this month but seen they've pushed it back to October 29th. Warner scheduled a complete set and a 2 trilogy set reported by 4kfilme. But only time will tell.
Even if the 4K movie that you buy isn't in real 4K & is just upscaled 4K, no one should be scared. There are some upscaled 4K movies that look beautiful on a 4K TV, such as "Spider-Man: Into the Spider-Verse" & "Pacific Rim". It's all about picture & sound quality like HDR/HDR 10+, Dolby Atmos Dolby Vision, etc.
Just got my first atmos system and your vids kept coming up in my movie research. Subbed great content.
Thanks Zach!
Always good stuff man. There is a slight difference in the discs as if it was just a bluray disc it could be read by bluray players. But I think I see what you were going for!
I over simplified it for the video - but you get the point!
They can be, there are locks on your consumer Bluray players. 4K blu rays are ripped all the time to the web, using regular old blu ray drives for the computer. Just firmware updates were needed at the most!! (The more you know 🌟✨✨)
Producer Evan - This reply should be pinned to the top of the comments section if at all possible.
@@producerevan88 tell me more :)
How do people not understand this.
Bluray: 1080p
4K Bluray: 2160p
The resolution of the master does not change this
@Scott Luther I agree with you Scott. The source needs to be 2160p otherwise it is just upscaling (which sucks and is a scam)
@@DragonboltBlastter Upscaling is not a scam. There are plenty of A.I out there that are extremely accurate at upscaling to 4k from 1080p. Obviously they won't look as good as native 4k, but they still look streets ahead of 1080p.
Appreciate the video and you trying to inform people better. While not all your information is 100 percent accurate as 4K discs are less compressed than a blu-ray and dvd they are still compressed. I’m glad to see you not get the criterion blu-ray and get the studio canal 4K instead. I bought the fog on 4K from them and it was well worth it.
I’m glad you are helping to get this information out for people to hear and see. 4k HDR is so much better than any other way to watch films today. I even still watch vhs & laserdiscs but the quality is just amazing to see where we are at today. Films have never looked better.
Wow... this is SHOCKINGLY inaccurate. The difference between true 4K discs and 4k mastered Blu-rays have NOTHING to with being compressed or not. Blu-rays are typically compressed with essentially h.264 compression while 4K Blu-rays are compressed with h.265, which is just a newer, more efficient method of compression. The difference is actually ALL about the resolution. 4K masters are typically 3840x2160 (that’s 3840 pixels wide by 2160 pixels high) and for a 4k Blu-ray that full resolution can be retained. For standard Blu-ray... that 3840x2160 4K master has to have it’s resolution (not its data rate) reduced because the maximum picture resolution for HD is 1920 pixels wide by 1080 pixels high. For every 4 pixels in the 4k master, those have to be combined into 1 pixel for the HD (Blu-ray) master. So for every 4 pixels of detail in 4K you only get 1 pixel in HD. This is further complicated by the fact that most modern-ish movies were finished at a resolution just above HD (in 2K) and then those masters are UPCONVERTED to 4K ( so every pixel is split into 4 using upconversion algorithms). But the bitrate or compression have ZERO to do with this. In fact, you could very easily fit a true 4K film on a 50GB standard Blu-ray (and even a 25GB one). Most iTunes and VUDU 4K file sizes are well under 25GB for a standard film.
Thanks for the vid, Jeff, I actually had been wondering this very subject.
@FilmsAtHome the size of the disc is not the only difference. The compression standard is a huge difference. Blu Ray uses h.264 and 4k uses h.265 wich gives same quality but almost half the size of h.264.
Good addition, yes this is true.
UHD blu-ray also has higher data transfer / bitrate(s) .. disc capacity doesn't even matter if the data doesn't get to the display quickly enough
Lethal weapon needs a 4k release
Get on Twitter and talk to Warner Home Video about that. I'd take 1 and 2 with new 4k restorations from the OCN's plus Dolby Atmos.
Thank you so much for breaking this down for us collectors! I never knew
Thanks for the video. I have a new 4K Samsung Q90R and I don't know that much about 4K and you help to educate me on it. I have seen 4K through Prime Video and man, the picture quality is amazing! It is like being there! I watch 4K TV on Pluto and shows and movies through my Android Box at 720 resolution and even with upscaling, it doesn't even come close to the quality of the 4K Stream from Prime Video! I don't own a 4K disc player yet, but after your explanation, if I purchase one, I will try to get the true 4K player. I have seen files on my Android Box that have Bluray in the name so I always thought they were the best quality but you said the Ultra High Definition 4K is better with the 50+ GBs of data. I have seen these large files on the Box (not too often) and now I know they are the true 4K streams! Thanks again, I am learning!
Really like your channel and happy to see that you’re a true lover of film. Important clarification below about 4K scam master size provided by Aaron Rust, but keep up the good work. Been enjoying your great videos!
It’s so funny that you posted this today, because I JUST got my Criterion copy of Portrait of a Lady on Fire yesterday and it’s a 4K digital master, but it’s only a Blu-ray Disc. Like, why not just throw it on a UHD disc? I don’t get it.
Criterion doesn’t make 4K discs yet-well, at least not in North America (don’t know ’bout the UK).
Beau, I get what you’re saying. But from my understanding it’s at least partially a cost-prohibitive thing. Apparently true 4K Ultra HD Blu-ray Discs are more expensive to manufacture.
Before I buy a UHD blu ray disc. How can i know if the movie is native 2160p or upscaled?
Great video mate. Not to take anything away from the ultra talented crews that restore some of our favourite movies, but I feel like the ‘4K’ term is thrown about as a marketing gimmick sometimes and can be a little misleading. Keep up the great work buddy 👍🏻💿👍🏻💿
I like your channel because you're not trying to BS anyone. There are a lot of people out there with wild imaginations that would tell you they can clearly see a drastic difference between the Dr. Stangelove 4k and the Criterion blu ray. The fact is its a subtle quality difference if the the blu ray was well done. To top that, the laws of nature can't be broken, if a viewer doesn't have a large enough TV, the human eye can't process the microscopic differences.
Home Video Disc Format Ranking from worst to best potential quality: DVD -> Blu-Ray (with 2K Master) -> Blu-Ray (with 4K Master) -> 4K UHD Blu-Ray (with 4K Master and HDR)
Of course most 4k disks still have 2k di's so... But that said generally a 4k uhd disk with a 2k di will still look and sound better then a bluray with a 4k master. But it depends
Great video dude, I had no idea that 4k on bluray wasn't true 4k and was compressed.
Well every disc is compressed. The only thing that isn’t compressed is actual film from a camera. The 4k disc is the least compressed way to watch a film. Blu-ray is way more compressed than 4K but 4k still need to compress the image from the true film/ camera to store it on the disc.
You're starting to look like Prince Vultan. Pretty rad.
Hello from Ireland! Just wanted to say that I love the videos and find them super interesting, also, would you ever consider doing movie reviews?
Studios have been doing 4K and 8K film restorations for awhile (Ridley Scott Mastered Blade Runner Final Cut in 4K and 8K shots for VFX for example). Studio masters get distributed for a different master for a home format. They are not "compressing" 4K to 2K (or 1080P), instead they are rescaled (sampling pixels down). "Compression" is a different term referring to how the movie's bitrate is shrunken to save file space. You're also in error that a blu-ray holds up to 25GB: it is a format that was introduced to have multiple layers. It's also an older format, so movies are compressed in: h.264. A 4K movie requires more space because it not only has 4x the resolution, but HDR, and 7.1 core audio for Atmos or DTS:X. So in order to fit this extra info, a new codec was used: h.265. Standard BD can also be made with 4 layer 100GB capability. The difference between the two is software formats. UHD resolution, HDR, and Atmos or DTS:X are newer formats that are incompatible with older blu-ray formats. Blu-ray is an older format made for 1080P consumer standards: because of the differences in software format, blu-ray is an older standard that's incompatible with these new video and audio format. Also, the studio master is larger than the compression used for home distribution....a cinema 2K intermediate is much larger than 100GB, for example, because it's uncompressed layers of video and VFX, in a higher color depth. You claim that studios were upscaling DVDs, but again, studios have different masters than the home distribution. I know, for example, the marketing for the Star Trek set said that STIIWOK had a restoration, and the others a remaster. The uninformed internet was saying, "see these other movies are up-converted DVDs". The reality was that the other movies were taken from earlier 1080i telecines made for HDTV.
Thank you for this video!! This has been something I've been wondering about for a while now.👍
Very good explanation on the differences and how this all works 👌👍👍
Geek away Jeff, good breakdown and always learning more about our films at home!
Excellent comments too.😎🍿
Live your show dude.
Question.
I'm noticing some for 4k discs are of a lower quality than others.
I have deadpool on 4k and it is about the same quality as the blue ray.
Is there something i should be looking out for on the packaging?
I always look for the hdr badge but there is definitely a difference between my deadpool and other 4k films
What equipment are you using to watch? Because I have both blu day and 4K for Deadpool, and they are night and day. Blu Ray looks like I’m watching on a high end tv. 4K version looks like I’m watching through my window. Also some 4K releases are what is commonly know as “fake 4K” while others are truer 4K transfers. Fake 4K typically use a 2k intermediary creating more compression than would otherwise be seen on a proper 4K transfer.
Hey Jeff! I’m Ready To See Your Harry Potter 4K Reviews! I Just Picked Up The Steelbook Collection! 👍🏽
I've got them and watched them all. A really great set, really enjoyed all of the films. All of them are an improvement over their respective blu ray versions.
Richard Skelding GREAT!!!! 👍🏽
Love the channel, enjoyed latest vid. Be advised under the blu ray format specification , the format only supports up to 1920x1080 resolution, regardless of available disc space.
I was wondering your opinions on 4k streams vs a 1080p blu-day disc, are blurays a better overall picture than a 4k stream?
I think1080p is just as brilliant picture as 4k but that's me
James Lee, resolution wise, yes I agree that 1080p looks very close. It’s HDR that pushes 4K UHD ahead imo. HDR implementation will determine how much better a particular movie looks on UHD vs Bluray. Some are hardly better at all and others are significantly better.
Bruce Carter i mean the 4k UHD blu-ray is always better than anything else, except one or two releases, like terminator 2, but i mean 4k streams vs 1080p blu rays, because although the stream is a higher resolution, it will have a lower bit-rate than the blu ray, of course the audio is often worse on the stream, so i’m talking picture wise, but the 4k blu-ray is always better, i was just wondering about some opinions on 4k streams vs the blu-ray
@@brucecarter6205 thanks
it is not only storage, resolution is also higher on 4k bluray discs
Well the storage gives the ability to have a higher resolution
Okay, here's a homework assignment for you. How about your recommendations for Blu-rays that were mastered in 4k, that look almost as good as a 4K disc just minus the HDR?
Two examples from my list, Elysium, and the Tom Cruise film Live, Die, Repeat. Except for the formation of HDR, they are brilliantly mastered discs.
I have not gotten around to watching it yet, but I am told the most recent release of Michael Mann's Heat also qualifies.
Night of the Comet collectors edition from scream factory Blu Ray looks so freaking good i was stunned that it was a Blu Ray and not a 4K
Great video! It’s answered so questions I had! But I have one more. What’s the difference between shot in 2k and upscaled to 4K. And just shot in 4K? Do they look the same? Are they “true 4K”? And how do I know if it’s upscaled or shot in 4K?
You can tell from the quality but for an easy this is true 4k you only know if they tell you or it is listed from the studio. Most 4K release be it 2k upscales will look great but true 4k looks far superior. It really is a look and you know thing. Most packaging will not say it is a 4k master or a 2k master
Depending on the factors surrounding the source material, there are actually 2k upconverts on 4k Blu-ray that look better than native 4k releases. There is no guarantee that a native 4k title will look better than a 2k file upconverted to 4k. It just depends. However, they can both look much better than regular Blu-ray unless the studio has majorly botched the transfer and/or mastering. Thankfully, there are just a few titles that are very disappointing on 4k Blu-ray.
THANKS, FOR THIS VALUABLE KNOWLEDGE FROM THE BOTTOM OF MY HEART! LOVED IT!
Awesome video brother! Great explanation!!
When you’re in a shop and holding a movie in your hand and looking at the back of the case, how do know if it’s Native 4K or Upscaled 4K?
You'll probably have to use Google.
You don't and it's BS
Generally, anything shot on actual film that is either old or doesn't have much CG is gonna have a native 4K picture. Most modern films are usually mastered at 2K due to time constraints with CG and post-production, but there are some good recent films that are at a native 4K picture like Joker or Power Rangers. For old films just assume they're 4K but for newer ones I'd do a google search.
Just wanted to add. The compression algorithm matters as well. A UHD bluray will use h.265, where a regular bluray will use h. 264. A DVD will use mpeg2. H.265 has less compression than h264. H264 will have less than dvd. A UHD disk upscaled or not "should" look better than a bluray because of less compression.
Thank you for helping me out with my choice on my 4k and blue ray
To my understanding each format that releases has a separate license for example when scream does a release it often doesn't have a digital code because they were only granted the license for a Blu-ray release
Aaron Lewis Good tip!
Hey I have a question about the boutique labels. Which one is better for things like grandma’s hands science fiction.
Sadly, in a conversation I had this past February with Jon Mulvaney of Criterion regarding their great 4K transfers, he was pretty emphatic that Criterion was not going to get into 4K media in the foreseeable future.
He's holding a lot of great films up. If they won't release on 4k disc, the original license holders need to give them to Arrow (hopefully not Studio Canal) or some other distributor that would do a solid job with 4k discs.
Did he provide any reasoning for this decision?
Love your videos.... do you ever think there be 8K disc movies one day?
I don’t think it’s worth it. It’s so unnecessary but who knows they might try
Maybe decades in the future. 8k is only beneficial if you have a HUGE projection screen. 4k with true Rec 2020 color and solid 12 bit HDR is really all you need for the home.
@@dan_hitchman007 I was just concerned because I dont want to collect 4K disc movies then say 5 years down the road they start bringing out 8K for the same movies.
@@danrolinson1213 I think it's safe to say that 4k discs will be the last physical medium for A/V, so hop to it and support the format. Streaming of 8k will be laughable because they have to squeeze 4k video and audio so hard already. If you watch streamed 4k content on a projector and large screen you see the fragile, low bitrate compression really fall apart. Most content only has up to 4k of image detail anyway, until you get into 65mm epics of yesteryear and filmed IMAX documentary releases.
Just wanna know if 4k is worth the investment? Got my whole movie collection on bluray now, do i re buy in 4k or is it really not worth the upgrade? Or at least not yet?
It depends on how seriously you take movie viewing experience. For most people nowadays, owing physical isn’t even worth it. For cinephiles hi-if viewing experience is paramount, and therefore it would be worth the upgrade. If you do not know where you stand maybe take a chance. Worst case you blow a few hundred bucks, best case you find a whole new world of at home cinema.
Arrow would have made a killing if the had done RoboCop in 4k uhd. Pitch black is a good movie but RoboCop is iconic.
It's only if Arrow can gain the rights to MGM's 4k restoration files. They may be looking for other titles to release on 4k Blu-ray if their initial 4k titles sell well. One of their first is Cinema Paradiso with Dolby Vision. That's an amazing film.
Oh yes! This issue.....
Might I add the advent of 8k recordings > mastered in 2k > forther upscaled to 4k and downed to 1080p.... and the sudden oddities that this has brought up in the final product
Great video but I have a question, if the discs are read the same but have different storage, why do I need a 4K player? Thanks, keep the vids coming
Kind of surprised that this is still being debated, especially by the enthusiast community.
Also depends on how the film was originally shot.
Great info as always, so long story short i should wait for 4k 2.0 (disc's)
10 people didn't understand this lol. But UHD discs read at a higher bandwidth capacity vs standard bluray which is why it took so long to release the UHD format to reach the consumers.
I currently use my xbox one x as my main 4k player...but been having issues and thinking of replacing it for a stand alone 4k player...any recomendation?
Thanks for the explanation, very informative for the layman.
Great video, love stuff like this!
Can’t wait to get my OLED and 4K plauer
Thank you for the video
I don't understand why in 2019/2020 movies as being released as 4k digital restoration when 4K disks exist...
in addition, if the video is 1080p without HDR, what is acutally the difference compared to the original bluray? why does the 4K restoration look better?
PS it seems like the audio is out of sync.
Great video as usual Geoff
I know this is an older video, but I just watched it and it helped me a lot, so thanks! What about the instances where they've compared frames of Criterion blu-rays to other company's 4Ks & shown that the Criterion blu looks superior? Pan's Labyrinth comes to mind. How does Disney manage to make a 4K disc look worse than their blu-ray, like Pirates of the Caribbean?There's still a lot I don't understand.
Great video. But I noticed on my end it's a bit out of sync.
I'd really love to see the original Texas Chainsaw Massacre on 4k ultra
@Repo man Thanks 🙌
very informative. I look forward to more
This seems rather long-winded and partly incorrect. A "4K Remaster" means the studio reassembled the project using modern, higher quality processes (ie: 4k scans of original film) and that the disc you hold in your hand was created using that higher quality source material. However, to fit this new 4K master onto a standard blu-ray disc means it has to be down-scaled and highly compressed to fit the rigid specifications of the blu-ray disc format, which doesn't allow 4K. No amount of "remaster bragging" on the packaging is going to mean your bog-standard blu-ray disc contains a 4K film. Blu-ray is 1080p. That 1080p blu-ray will look as good as it can within the confines of that format. That's all the 4K remastered source offers -- a better source to create copies from. Even a modern VHS release could say "from a 4K remastered source" and it'd be true. But a VHS tape and player don't support 4K, so, like the blu-ray copy, the 4K master would have to be shrunken down and go through a number of other awful steps before existing as a relic of the 20th century. The 4K source would assure that the VHS copy looked as good as possible, but ultimately it's just VHS in 480i with 3:2 pulldown... not a magic 4K UltraHD VHS.
In short, "from a 4K master" means "we have a really great master copy of this movie, and we've crammed it onto this consumer disc according to the disc and player's specifications. Important note: Only discs that display the 4K UltraHD logo contain a 4K copy of the film. Sorry for the confusion. Look for the logo to know what you're getting. Blu-ray is 1080p, 4K UltraHD is 2160p. The stuff we write back here is meant to sell you on our product, even if it is misleading. Again, sorry."
Thank you! I was just going to say the same thing. Bluray is 1080p. It doesn't matter what resolution the source material is, if you buy it on bluray it can only be 1080p. Even if your bluray player upscales, or you play it on a 4K bluray player, you are jusy getting a 1080p picture (upscaled). For true 4k you have to use a 4k UHD disk on a 4K UHD player (on a 4K TV)
Thanks for this video, this confused the hell out of me.💙🤔
Blu-ray is 1080p resolution with an 8 bit, Rec 709 color gamut , and Standard Dynamic Range (with a limited capability and a decades old spec for HD video). 4k Blu-ray is 2160p resolution with 10 bit (or 12 bit with a full Dolby Vision encode), wider Cinema P3 color gamut (wrapped in a Rec 2020 wrapper), with High Dynamic Range (almost always).
Hello. Why won't a uhd 4k disc play on a standard blu ray player if it's about storage size? Thanks
The players aren’t designed for the larger discs. They can’t read them.
The decode chip. Thats why some if not most computer blu ray players/burners can do both after an update, the decode on many of those is done on the pc itself.
Producer Evan - The same for this reply, as well (i.e., it needs to be pinned up at the top).
What did they do to HEAT 4k ? I need you to test it yourself ,I think the blursy looks better
I've been asked this a fair bit on my channel too. It can be quite difficult explaining the difference. It doesn't help that all 4K Blu-rays aren't made equal - depending on restoration, transfer, and encode, there can be massive differences.
Sadly not enough people will care about this or even know about it. I've had too many conversations with people about this and their only response is: well, is the movie on Netflix...? I hate hearing that, lol, like Netflix is the be all end all of all content ever now....lol.
I thought this was going to be about titles that are released on UHD BD from upscaled 2K masters.
Are there any examples where blu ray actually out does the 4k?
I have heard T2 4k is pretty bad, I'm guessing it comes down to how they get mastered on either format?
I recently updated to 4k and can see a huge difference. Now slowly upgrading my favourite movies again!.
I was around for VHS, must have replaced some of my movies about 6 times now. 🙂
Hi Jeff! Just finished watching your mastered in 4k video. I think you should do a video on Sony’s mastered in 4k x.v video color grading. I would love to see that...it’s like a forgotten secret!
Wish studios were honest with their packaging, in terms of movies that are truly mastered in 4K DI and released on 4K Blu Ray, vs mastered in 2K DI and still released in 4K Blu Ray. Aside from the resolution, HDR really makes a huge difference with most titles, with the bonus if it is truly mastered in 4K.
For movies mastered in 2K, in my opinion, there is no reason why it can't be released on standard Blu Ray with HDR?? I think the storage on a standard 50GB Blu Ray would suffice for added HDR encoding for those native 2K releases. Just a thought.
What is the Name of the Website with all film camera details?
I elected to preorder the Criterion release of Parasite even though it is not 4K. Hopefully I can grab a 4K copy cheap eventually.
I figured it meant we made a 4K transfer ready for ultra HD and then transcoded res to 1920 x 1080p, not compressed
Thanks for the explanation!
great video, easy to understand now. but i still could not get the version of jaws you had its just not available only one version of 4k is available. maybe its just the uk. i dont know.
People are daft - basically top picture quality will be in black box stating 4K, everything else in the blue box the quality won't be as good!!!
I agree there!
That's why i would hate a Disc break during all upcoming LOTR + HOBBIT Films on UHD!
Thanks for the valuable info..I appreciate it.
The question for Criterion is: How much compression do their movies undergo since they typically have so much extra content on the same disc?
I just download all my 4k HDR movies off RARBG anywhere from about 10GB-80GB a movie got over 100 downloaded in HDR 4k but noticed some only come up at 1080p HDR on my Hisense H9F .....but by far the best movie I've seen so far for PQ is IMAX Dunkirk and new bad boys for life movie was good to and Prometheus movies as well
Is the movie fury on 4k and have you done a review on it ? I bought the steelbook when it came out remastered in 4k but i want it in 4k ultra hd with HDR , also does it come with a dolby atmos track?
@@alexfernandez8083 The Dolby Atmos track is excellent. Very enveloping. The bass is intense!
There used to be a website devoted to true 4K and fake 4k releases called realorfake4k.com. When it was online, it could be determined that many 4K HDR releases were in fact just 2K to 4K upscales. The website went offline in fall of 2018, but there are snapshots available on the Way Back Machine.
between the video and the discussion below, I learned something. Not sure that the best answer is but I will not be buying a straight 4K-Blu-ray player if I even buy another one. I am really starting to feel like I might as well just stream. The ONLY place I can rent movies is Red Box and has anyone noticed how slowly they are getting new releases nowadays? I went in last week and looked, and they still had the movie I had rented on March 7th listed on the first page of recent releases. On top of this, was looking at disc players recently and good ones cost way too much and Samsung has just dumped the market. The ONLY thing I could find out there that was affordable were the LG's. I really have my doubts about the whole section of this industry. There seem to be no perfect answers.
For me personally, 4K UHD discs are not worth it. I have a home cinema with a 4K projector(Optoma UHD51) and a 4K bluray player(Panasonic DP-UB450K). I have tested both the 4K UHD and blu-ray version on several movies. My blu-ray player does a great job upscaling my normal blu-ray discs to 4K. That means I can't see a difference in quality. HDR is of course another subejct, but my projector is not good enough to handle that and that seems for most projectors actually..
Native 4K D.I is worth it upscaled not so much unless a movie you really like.
I will say though Blu Ray and 4K UHD Blu Ray can coexist. Some films don’t lend themselves to the 4K UHD format and 1080 is just fine. But, for me 65/70mm films are prime for 4K UHD Blu Ray. We have Lawrence, 2001, now Patton or Sound Of Music need to come out.
If transferred and mastered correctly, ALL films will benefit from UHD Blu-ray disc releases. You are limiting yourself unnecessarily. Jaws is on UHD Blu-ray and it looks great. 35mm. A League of Their Own was released on UHD Blu-ray and it looks amazing. 35mm.
