I’ve been collecting 4K Blu-ray discs for years now, and pretty much everything I buy is in the format if it’s available. I value having the best quality that I can get, and that’s what a 4K Blu-ray disc offers. The downside to this is that it’s the most expensive format on the market by a good margin. DVDs are almost dirt cheap in comparison, but there’s a significant drop in visual and audio quality on those discs when compared to the 4K counterparts.
There’s nothing inherently wrong if you still enjoy picking up a DVD, and the price is a huge factor in that. In fact, I’d say that’s the biggest difference I’ve noticed in making the leap from cheaper physical media to expensive 4K discs. Even the difference from regular Blu-ray to 4K Blu-ray is a big jump. Websites like GRUV frequently run deals, and at the time of this writing, there’s a 3 for $33 deal for three Blu-rays, so you’ll see more frequent sales, and sales at a lower price than what you see from the 4K format.
Blu-ray and 4K Blu-ray both look excellent, and while 4K has the benefit of a higher resolution and HDR, I’m not sure how much that matters to the average person. A lot of people have their TV placed far enough away from their couch where the resolution gain is negligible, and if that’s you, you might get more value out of a regular Blu-ray disc.

What video compression format is most commonly used by major 4K streaming services like Netflix and Disney+?
Correct! H.265, also known as HEVC, is the dominant codec for 4K streaming because it compresses video more efficiently than older formats. However, even HEVC has to make significant sacrifices in quality to fit 4K content into manageable bitrates for internet delivery.
Not quite. The answer is H.265 (HEVC). While H.264 is still widely used for HD streaming, 4K content requires the superior compression efficiency of H.265 to keep file sizes practical — though that compression still comes at a visual cost.
What is the maximum bitrate of a standard DVD’s video stream?
Correct! A standard DVD tops out at around 9.8 Mbps for its video stream. While that sounds modest compared to 4K resolutions, the key is that this bitrate is delivering 480p content — meaning far less data is being squeezed, and compression artefacts are far less visible.
Not quite. A standard DVD’s maximum video bitrate is approximately 9.8 Mbps. That figure might seem low, but because it’s only encoding 480p resolution, the compression is far less aggressive and the picture can look surprisingly clean and film-like.
Approximately what bitrate does Netflix typically use to stream 4K HDR content?
Correct! Netflix streams 4K HDR at roughly 15–25 Mbps, which sounds decent but is actually quite compressed for content at that resolution. A 4K Blu-ray disc, by comparison, can deliver bitrates of 80–100 Mbps, which is why physical media still wins on raw picture quality.
Not quite. Netflix typically streams 4K HDR at around 15–25 Mbps. This is dramatically lower than a 4K Blu-ray disc’s potential 80–100 Mbps, meaning the streaming version must discard a significant amount of visual information to fit through your internet connection.
What visual artefact is most commonly caused by heavy video compression in 4K streaming?
Correct! Banding — where smooth colour gradients appear as stepped blocks — and blocking artefacts are the telltale signs of aggressive compression. You’ll often notice banding in dark skies or shadowy scenes in 4K streams, something far less common on physical media.
Not quite. The answer is banding and blocking artefacts. These appear when a codec discards too much colour and detail data to save space. Smooth gradients like dark skies can show visible ‘steps’ of colour, and fast motion can break into blocky patches — both common in heavily compressed 4K streams.
What is the native resolution of a standard DVD?
Correct! DVDs store video at 720×480 pixels for NTSC regions (like the US) or 720×576 for PAL regions (like Europe). Despite this relatively low resolution, the efficient use of bitrate and lack of heavy compression can make DVDs appear remarkably sharp and film-like on a modest screen.
Not quite. The answer is 720×480 for NTSC or 720×576 for PAL. These resolutions are a fraction of 4K’s 3840×2160, yet a well-mastered DVD can still look impressive because the compression is far less severe relative to the amount of picture detail being encoded.
In what year was the DVD format officially launched for consumers in the United States?
Correct! DVDs launched in the US in 1997, following an earlier debut in Japan in late 1996. The format was a massive leap over VHS, offering cleaner picture, chapter selection, and surround sound — and it dominated home video for over a decade before streaming began to take hold.
Not quite. The DVD launched in the United States in 1997. It had debuted in Japan a year earlier in 1996, and its combination of better picture, digital audio, and durability over VHS quickly made it the dominant home video format well into the 2000s.
What does ‘HDR’ stand for in the context of modern 4K streaming and display technology?
Correct! HDR stands for High Dynamic Range, and it refers to a wider range of brightness levels and colours that a display can show. When properly implemented, HDR can make a bigger perceptual difference than the jump to 4K resolution alone — but poor streaming compression can undermine its impact.
Not quite. HDR stands for High Dynamic Range. It allows displays to show brighter highlights and deeper shadows simultaneously, with a wider colour gamut. Ironically, the heavy compression used in 4K streaming can introduce artefacts that make HDR content look worse than well-mastered SDR video on disc.
What is the term for the process where a video codec selectively discards information deemed less visible to the human eye in order to reduce file size?
Correct! Lossy compression is the technique at the heart of all major streaming video codecs. By discarding data the human eye supposedly won’t notice — fine textures, subtle colour differences — codecs dramatically reduce file sizes. But at low bitrates, those shortcuts become very noticeable indeed.
Not quite. The answer is lossy compression. Unlike lossless encoding, which preserves every bit of data, lossy compression permanently discards information to shrink file sizes. At the low bitrates used by streaming services, this can strip away fine detail, crush shadow gradients, and introduce the artefacts that make 4K streams look worse than a DVD.

The price of 4K is a major deterrent
I understand wanting a cheaper alternative
The cost of everything has been going up lately, so it’s not really a secret that people have to cut back in certain areas. What I’ve noticed is that I’ve slowed down significantly with new 4K releases. I still pick up things during specific sales, and the 4K Troy from Arrow is something I snagged from Barnes and Noble for $25, but deals like those aren’t always running. I find major studio releases tend to cost $35, and I just don’t want to pay that for a movie right now. It feels like sales in general aren’t as frequent as they used to be, and with fewer stores selling physical media, it’s not a good spot to be in as a consumer.
I have such a backlog of 4K films that I own that I could go years without buying anything new before I get through everything, but I’d still like to get more. What I’ve been doing more frequently is not really worrying about the format when I pick something up on sale. During the most recent Prime Day sale, I ended up getting Bugonia on Blu-ray instead of 4K due to the price difference between the two.
When it comes to physical media, I like the convenience of having something physically instead of tracking it down on a streaming service. Whether it’s on Blu-ray or 4K Blu-ray isn’t the end of the world for me. While I’d prefer everything to be on 4K Blu-ray, if prices stay where they are, I can see myself adding more Blu-ray discs to the collection.
Watching things is the point of this hobby
Save some money where you can
I don’t know about you, but when I sit down to watch a movie, I don’t think much about what resolution it’s in when it starts playing. On a recent plane ride, I watched Michael on a tiny pixelated screen on the back of an airplane seat, and I still got an enjoyable experience out of it. If a movie is good, I believe it’ll transcend whatever format you’re watching it in, and you’ll have a good time. I know I would’ve enjoyed it more at home with the Dolby Atmos soundtrack in full effect instead of something being stuck on some substandard stereo audio coming out of some cheap earbuds.
Blu-ray quality is still good enough for most cases. 1080p still looks great, and many (but not all) discs come with a Dolby Atmos soundtrack that takes advantage of my surround sound system. The biggest loss is having no HDR, but even that’s something I can put up with. Good HDR can enhance a movie, but it’ll never turn a bad one into a good one. People like to use Gemini Man as an example of a stunning 4K disc, but that’s strictly in terms of how it looks instead of how good it actually is. I like HDR as much as the next person, but I would sweat it if I’m able to save $20 on a disc.
If you’re new to the hobby, there are plenty of 4K discs that can be found on sale at any given time, but you’ll quickly realize it’s the same ones always on sale. Once you add the heavy hitters to your collection — The Dark Knight Trilogy, Lord of the Rings, Blade Runner, etc. — then you’ll be left scavenging for other deals. That’s not to say they don’t exist, but they certainly
