One of my favorite film genres is Sci-Fi, and it helps that there are so many subsections of it. I never feel like I’m running out of things to watch. Sometimes I want to watch large-scale fights with aliens, but sometimes I want a more human-centric story. For the latter, I find that post-apocalyptic fits that bill. These stories often focus on a single person trying to survive an unfamiliar world, and while they might not be as action-packed as other genres, I still gravitate toward them. Of course, there are still plenty of examples with lots of action.
There are also a bunch of options on 4K Blu-ray for this genre, so I always have something to reach for on the shelf, and there are new releases quite often. I wouldn’t say it’s a genre I like to binge, since it can be pretty depressing sometimes, but I never come away from one thinking that it didn’t look great. Quieter films like these often have a good, ambient soundtrack as well. The best of the best really pull you into the world, and that’s what I think I like them so much. Here’s a look at four of my favorites.
UHD Blu-ray technology
Trivia challenge
4K discs, Dolby Vision, and beyond — how much do you really know about UHD
Blu-ray?
4K VideoAudioHardwareFormatsStandards
What is the maximum video resolution supported by the UHD Blu-ray format?
Correct! UHD Blu-ray supports a maximum resolution of 3840 x 2160,
commonly known as 4K UHD. This is four times the pixel count of standard 1080p Full HD Blu-ray,
delivering stunning on-screen detail.
Not quite. The answer is 3840 x 2160, which is standard 4K UHD
resolution. While 8K (7680 x 4320) exists as a consumer format, UHD Blu-ray tops out at 4K — still a
massive leap over traditional Full HD discs.
What is the typical maximum data capacity of a dual-layer UHD Blu-ray disc?
Correct! A dual-layer UHD Blu-ray disc can hold up to 100GB of data.
This extra capacity over standard Blu-ray’s 50GB ceiling allows studios to pack in high-bitrate 4K video
alongside lossless audio tracks and bonus features.
Not quite. The correct answer is 100GB for a dual-layer UHD Blu-ray
disc. Standard Blu-ray maxes out at 50GB on a dual-layer disc, but UHD Blu-ray needed more headroom to
accommodate the much larger 4K video files and premium audio formats.
Which of the following lossless audio formats is natively supported on UHD Blu-ray
discs?
Correct! DTS-HD Master Audio is one of the lossless audio formats
officially supported by the UHD Blu-ray specification. It delivers bit-for-bit identical audio to the
studio master, making it a favourite among home cinema enthusiasts.
Not quite. DTS-HD Master Audio is the correct answer. Dolby Digital Plus
is actually a lossy compressed format, not lossless, while MP3 Surround and AAC 5.1 are not part of the
UHD Blu-ray audio specification at all.
Which High Dynamic Range (HDR) format was mandatory in the original UHD Blu-ray
specification?
Correct! HDR10 is the mandatory baseline HDR format for all UHD Blu-ray
discs. It uses static metadata and supports up to 10-bit colour depth with a peak brightness of 10,000
nits, significantly improving contrast and colour range over SDR content.
Not quite. HDR10 is the mandatory HDR format in the UHD Blu-ray spec.
Dolby Vision and HDR10+ are optional enhancements that some studios add on top, but every UHD Blu-ray
player and disc must support HDR10 as the baseline standard.
What laser colour is used in UHD Blu-ray players to read discs?
Correct! UHD Blu-ray players use a violet (blue-violet) laser with a
wavelength of 405nm, the same as standard Blu-ray. This shorter wavelength compared to the red laser
used in DVDs allows data to be packed much more densely on the disc surface.
Not quite. The answer is violet — specifically a blue-violet laser at
405nm. DVDs use a red laser at 650nm, and CDs use an infrared laser at 780nm. The shorter the
wavelength, the more data can be stored, which is why Blu-ray outpaces its predecessors.
What maximum video bitrate does the UHD Blu-ray specification allow for video
content?
Correct! The UHD Blu-ray specification allows a maximum video bitrate of
82 Mbps. This is substantially higher than standard Blu-ray’s 40 Mbps ceiling, enabling richer detail,
smoother gradients, and less compression artefacts in 4K content.
Not quite. The correct maximum video bitrate is 82 Mbps. Standard
Blu-ray tops out at 40 Mbps, and while streaming services like Netflix offer 4K, they typically deliver
it at just 15–25 Mbps — making physical UHD Blu-ray the highest quality option available to consumers.
Which video codec is most commonly used to encode 4K content on UHD Blu-ray discs?
Correct! H.265, also known as HEVC (High Efficiency Video Coding), is
the dominant codec used on UHD Blu-ray. It offers roughly twice the compression efficiency of H.264,
meaning studios can deliver 4K footage at high quality without exhausting the disc’s storage capacity.
Not quite. H.265 (HEVC) is the correct answer. While H.264 was the
workhorse of standard Blu-ray, it simply isn’t efficient enough to handle 4K video at acceptable quality
levels within the disc’s bitrate limits. AV1 is a newer codec but isn’t part of the UHD Blu-ray spec.
Which of the following connection types is required to pass a UHD Blu-ray signal at
full 4K HDR quality from a player to a TV?
Correct! HDMI 2.0 or higher is required to carry a 4K HDR signal from a
UHD Blu-ray player to a display. HDMI 2.0 supports the 18 Gbps bandwidth needed for 4K at 60fps with
HDR, whereas HDMI 1.4 maxes out at 4K/30fps without HDR support.
Not quite. HDMI 2.0 or higher is the correct answer. HDMI 1.4 can
technically carry a 4K signal but only at 30fps and without HDR, making it insufficient for the full UHD
Blu-ray experience. Component video is an analogue connection and cannot carry 4K signals at all.

Thanks for playing!
Mad Max: Fury Road is the shining example
Witness me!
Mad Max: Fury Road is the furthest thing from a quiet, post-apocalyptic setting, but I love it. This is one of the best action movies of all time, and it’s also one of the best looking and sounding 4K Blu-ray discs you can find. Even if you’re not a fan of action movies, I think you’ll be drawn in by this one.
While it’s deep into a franchise, you can easily hop into this without watching prior Mad Max films, although there’s nothing wrong with doing that. That’s actually what you’ll want to do if you want to see the quieter side of the post-apocalyptic genre. Fury Road doens’t have a Dolby Vision scan, but it still looks excellent with HDR10. It does have Dolby Atmos, so if you have a proper sound system for it, the soundtrack soars.
The new Planet of the Apes trilogy is worth a watch
Just because the old ones aren’t 4K
Before Matt Reeves entered Gotham City, he was known for the latter two movies in the excellent Planet of the Apes reboot trilogy. While it’s not quite post-apocalyptic, these movies show the downfall of man and the rise of the apes. It took me a long time to finally give them a chance after watching the first one, but I’m glad I eventually snagged that trilogy.
My favorite of the bunch might be Rise, but I’d say they’re all worth a look. Rise was shot on film, so it’s arguably the best-looking of the trilogy, but that’s really up for debate. The CGI, like a lot of CGI from the early 2010s, may not have aged very well, but I’d still say this is one of the best 4K post-apocalyptic movies available on the format.
Spielberg’s War of the Worlds is a good one
I come back to it a lot
I feel like Steven Spielberg’s War of the Worlds flies a little under the radar. It starred Tom Cruise, but it feels like people remember it for its press tour instead of the movie itself. Nevertheless, War of the Worlds is a more modern take on the idea, and while it might not be a full-blown post-apocalyptic story, it fits the bill well enough.
It has a Dolby Vision scan and a nice Dolby Atmos soundtrack. Dolby Vision shines here, and it helps those dark scenes look excellent. I don’t have much to complain about with the picture quality, and if you have an Atmos sound system, you’ll love what it does there. I don’t have much, or anything, to complain about here. This is one of my favorite 4K discs in my collection — Sci-Fi or not.
A Quiet Place is an interesting take on the genre
A really good soundtrack
A Quiet Place is the newest entry on this list, and I’d say it’s one of the movies worth grabbing the 4K for the most. This is because of the Dolby Atmos soundtrack, which is a little ironic considering it’s a movie where people are meant to stay quiet. I like movies like this, however, because it requires the filmmakers to put a lot of work into making the movie sound great, and when there is sound, it has to be worth it.
This is the type of movie I think of when I think of post-apocalyptic. The focus is more on the characters than the event taking place. This is a fully settled-in world, but if you’re looking to see what eventually led to this, you can check out A Quiet Place: Day One from 2024. I don’t like that one as much as the original two, but you might feel different.
