Varför köpa film på skiva när man kan streama?
- Bild- och ljudkvaliteten på skiva är betydligt bättre och framför allt jämn och inte beroende av ditt Wifi/internetuppkoppling
-Du får oftast en massa roligt extramaterial
-Skivan är din och du riskerar inte att favoritfilmen helt plötsligt försvinner från streamingtjänsten (Netflix byter ut filmer var 6-12 mån)
- James Bondfilmerna och SVT:s julkalendrar är några av filmerna som inte finns på Netflix samt alla Disneyfilmer och Star Wars
- Svenska Netflix har ca 3400 titlar (enligt bedömare, Netflix vill själv ej uppge hur många) och vi har inom kort 35000 titlar i lager
"When the A/V enthusiasts at WhatHiFi.com compared the three formats earlier this year, they found that the 4K streaming experience was actually more in line with watching a traditional 1080p Blu-ray — and that Blu-rays had a clear advantage in terms of contrast and color. 4K Ultra HD discs, meanwhile, looked far better than either.
Nor can streaming services handle the latest and greatest in surround sound technology — the gloriously rich and detailed seven-speaker sound produced by the Dolby TrueHD or DTS HD Master Audio standards that have been around on conventional Blu-rays for years. With the right setup, these audio formats can make big action scenes incredibly dynamic: The engine noise in Mad Max: Fury Road becomes a guttural roar; the gunshots in Heat’s bank robbery sequence almost seem to pierce your living room walls; the pod race in Star Wars: Episode I – The Phantom Menace ricochets across the speakers as if your couch has been transformed into a desert canyon on Tatooine. Streaming services offer five-speaker sound at lower fidelity, but if you have a modern surround system at home, you’re missing out on the full experience.
The problem for streaming is compression: The picture and sound information has to be processed in a way that allows it to be sent efficiently over the internet. And while compression has improved greatly over the years, it invariably means a loss of information along the way. Darker scenes tend to fare the worst, as sunsets that are supposed to gently fade from color to color turn into blocky digital stripes and rooms lit by firelight start to look chunky and pixelated, like web videos from 15 years ago. Discs, on the other hand, are right in the room with you, sent to your television on a high-quality cable, and thus don’t suffer from the same issues.
Physical media offers added features and consistent access. Streaming doesn’t.
There are other reasons to prefer physical media to streaming services beyond the technical aspects. Blu-rays and DVDs often come packed with extras, from commentary tracks to behind-the-scenes featurettes, that can help you understand the filmmakers and the filmmaking process.
Sure, some of these extras are just promotional material. But from time to time you discover something truly revealing: Full Tilt Boogie, a feature-length documentary about the making of From Dusk Till Dawn that for years came as part of the DVD package, remains one of the weirdest, rawest, and more fascinating looks at the making of a movie I’ve ever seen. Brad Bird’s director’s commentary on the deleted scenes of Mission: Impossible — Ghost Protocol shows how focused the production was on nailing the movie’s big action set pieces, almost to the point where the connecting material was an afterthought. The Criterion Collection edition of Michael Bay’s The Rock is worth it simply for the incredibly profane reel of outtakes.
This sort of extra material helps you understand how the movies you love are made, and the personalities of the people who make them. You won’t get any of this sort of filmmaking color from most streaming services.
More than anything else, though, it’s ownership that makes physical media an improvement over streaming services. Ownership means that the unknowable programming gods who manage those services can’t unexpectedly take away your favorite movie. Ownership means having a physical object that you can see, touch, hold, and display on your shelf. It means connecting with the thing itself, knowing that it is yours. And it means knowing that you can watch a movie whenever you want, as many times as you want, in the highest possible quality."
"Before we get into the testing, it’s worth looking at the specifications for Blu-ray and streaming services. On paper, Blu-ray is certainly the quality winner, with the standard supporting video encoded using H.264 at a resolution of 1,920x1,080, delivered at a bit-rate of up to 40Mbit/s.
Compare that to Netflix, which is representative of other streaming services. It also uses the H.264 codec at a resolution of 1,920x1,080, but streams at around 12Mbit/s maximum. That’s a big difference between the two. To get its streaming rate down, Netflix has to throw away more detail in its video stream compared to the Blu-ray version."
"Streaming services compresses your movies and shows a lot more than a Blu-ray would.
How much more? Well, to compare, we can look at the video’s bitrate, which basically means how many bits the video contains per second. Netflix doesn’t say exactly what the bitrate is for its 4K shows, but a help page recommends having at least an internet connection capable of streaming at least 25 megabits per second. Meanwhile, a Blu-ray “streams” (through your HDMI cable to your TV) at anywhere from 82 megabits per second to a whopping 128 megabits per second. That’s anywhere from 3-5x as fast as what Netflix recommends to watch its 4K movies.
The result is watching a show on Netflix will sometimes look a lot worse than if you were to watch those same shows on a Blu-ray. This is especially true of scenes with rain, snow, or confetti, which trip up compression algorithms more than usual. Some scenes—especially scenes with little motion and simple images, like say a cartoon—will look perfectly fine. But scenes with a lot of detail or movement can end up looking pixelated or choppy because compressing the show down to a streamable size throws out a lot of data."
"We compare a 4K stream with a 1080p Blu-ray. Shading, especially in the dark, is more nuanced on the Blu-ray. Colours are richer and more solid. You may not get the outright sharpness of a good 4K stream, but it is at maximum resolution the moment the video starts playing, and the latest 4K TVs do a good job of upscaling.
With 4K streaming and 1080p Blu-rays almost neck-and-neck: slightly greater resolution and sharpness of the streaming versus greater subtlety in colours and contrast on the Blu-ray, we look at 4K on disc. This is an entirely different matter. The video quality of a UHD Blu-ray (played on Panasonic's excellent DMP-UB900 Ultra HD Blu-ray player) is leaps and bounds over 4K streaming and regular Blu-ray.
The picture is crisp, with stunning clarity making the most of fine textures. Colours are vivid and subtly shaded, especially in dark scenes. That’s just with the standard dynamic range, a fairer fight against 4K streaming and Blu-ray. One of the best things about 4K BDs is high dynamic range (HDR) which ramps up contrast, brightness and colour range.
More colours makes for more realistic shading. Better contrast means a much harder visual kick. High peak brightness means greater increments at both ends of the light spectrum, which equals more detail in the lightest and darkest areas.
With HDR, the picture is gorgeous, and we reckon it is the future of home cinema. In conclusion: 4K streaming and 1080p Blu-rays have their own strengths and weaknesses, but both are easily beaten by the dynamism and subtlety witnessed on 4K Blu-ray.
This is one area where streaming loses out rather badly. Most people watching video on streaming services will not be doing so with a surround sound system. So what you tend to get from streaming is compressed Dolby Digital Plus. A few titles offer that in 7.1, but mostly it’s a 5.1.
Compare that to the uncompressed Dolby TrueHD or DTS HD Master Audio you get on Blu-rays, typically in 5.1 but regularly in 7.1. The weight, scale, detail and dynamic range on disc is a lot more intense, making for a more cinematic experience. Audio quality between standard Blu-ray and 4K BD is hard to differentiate.”
