Digital still can’t match 70mm IMAX. In fact, IMAX film is even higher resolution than regular 70mm as the film runs through horizontally rather than vertically so more space is used for the image.

But a lot of it has moved digital. IMAX has special laser projectors. They just are not as good. Also, there is a lot of LieMAX (smaller theaters given IMAX branding) that are pretty well all digital.

Actually it won't. A movie on a 4k blu ray is around 80gb without additional compression. And Oppenheimer is shot on 70mm which is more like 8k resolution. Still would fit on a micro SD of course

lemmy.world

It's way bigger than that. Usually cinemas receive movies in multiple terabyte hard drives. Thats because they are using JPEG2000 standard (it varies, but it is close to lossless) and a movie can take up anywhere from 500GB to 2TB (highly dependent on resolution, it can go above 2TB). https://en.wikipedia.org/wiki/JPEG_2000?wprov=sfla1

Some things to keep in mind about the theater experience.

  • Only a handful of theaters do film IMAX anymore. A lot of IMAX locations are just 4k DCP (Digital Cinema Package)
  • Most theaters in the world are digital projectors with a max resolution of 1998x1080 or 2048x858

Part of the reason these factors still exist is cost. A poorly maintained film projector with a lousy film print can ruin a movie going experience. Hollywood would sometimes release so very shitty prints. The digital projectors are much easier to maintain so the experience is often more ideal for the average movie goer.

Having said that, if a theater takes good care of their film projectors and they have a well made and well kept print, the experience can be amazing.

I'm no old-school cinephile, but I've listened to enough of them to understand that if you're really into the nitty gritty details and love soaking in every corner of a filmed image, there is no substitute for a large print screening. But YMMV.

I've never actually seen anything in 70mm IMAX, so idk! But I love the vibe of analog film and the way it looks, so to experience Nolan in the way he intended it at essentially 16k resolution is likely going to be incredible. Five hours is quite a lot though, especially to then watch a three hour movie. Maybe if you made a weekend out of it and stayed at a hotel or camped somewhere? I'm lucky that the closest one to me is only a 45 minute drive

Question for anyone reading.

I want to build a mancave downstairs, but I wouldn't watch enough things to warrant a TV. I was thinking of buying a projector. Projectors used to be expensive, very expensive. Good projectors still seem to be, however now there are a plethora of cheap projectors on sites like Ali, Temu, Amazon, etc. Is it worth buying a high quality projector? Will I notice the difference? Or can I get away with a $40 projector bought off one of those sites?

My plan would simply be to stream stuff off my phone. If a cheap projector is a bad idea, what is a good protector and how much would I need to pay? Also, anyone know what the best audio setup would be for this?

1

I bought an unknown brand on amazon for 250 maple syrup dollars and I'm pretty sure everything it says on the box is true. It's 1080p native and 450 lumens. I use it to watch movies outside. I have to wait until sunset but otherwise I'm really happy with the picture quality. This is the one I got. I think if you got anything less it would probably be okay for your needs, but you might regret not getting something better the first time.

If you're looking to keep costs super low I imagine you're better off going for a second hand projector over a cheap new one.

I've seen friends all buy types of these thinking they will get some good one and be impressed, 1080p, 3000lumens etc, all the specs say yes but the experience... no.

Go for an entry level from a brand that does projectors, eg I got Optoma but there's Epson, even acer is fine. I got a 720p with 1080p source, or BluRay rips and it looks very legit.

Of course you can go higher, but sounds like you just wanted to start out... Optoma H183 I think is mine.

2

Never owned one, but I have a hard time believing that $40 pocket projectors are any good. LED projectors at that price range are going to be pretty dim, so you'll absolutely need a dark room and to buy a proper projection screen if you want to see what's going on. I think most of those are also 720p, maybe 1080p. The speakers on such a projector are going to be awful, tinny garbage.

For the price of $40 1080p projector, $50 screen, and $60 Bluetooth sound bar, you could get a 43" 4k tv that's on sale somewhere.

1

I think you are misunderstanding some assumptions.

This will be for a "Manc-Ave" (SO ref) that I will likely, get maybe, at most a movies worth of my own time... And I do intend to watch all the scary moves that my wife won't allow down there... so that's a plus, although thet get boring quick.

Same here. Got a 77” OLED and a 5.1.4 system, no way the local theater can beat that. Even in a darkened theater the black levels on a projector are terrible. Also, HDR peak brightness is ‘meh’ in theaters as well.

And even within imax, there's differing qualities of the projector. It's all quite complicated and seems to be intentionally obfuscated.

Movies are getting really long and I don't know if I like it. I watched Across the Spider-verse recently which was I think 2.5 hours. To be fair it was a fantastic 2.5 hours, but every other movie in the theater was 2 hours plus and one was over 200 minutes long. Half of them were animated, which are usually on the short side and for good reason, because there's never any real meat to the story (Spider-verse again being the exception). Sometimes you just want a relaxed 1 hour 20 minute story; not every film has to be this gigantic grand experience.

Wasn't normal 35mm film about the equivalent of somewhere between 4k and 8k depending on the film stock?

21
lemm.ee

Something like that.

As far as lens optics, we’re really splitting hairs here. 70mm through a quality lens in an imax theater is going to look absolutely fantastic and stunning. Digital is just more convenient and at some point it will catch up and surpass film.

11
Shurimalreply
kbin.social

My point was more like that even IMAX film doesn't quite get to 18k equivalent, more like 12 to 16k. Honestly, anything above 4k (for normal widescreen content) even on big screens is barely noticeable if noticeable at all. THX recommends that the screen should cover 40° of your FOV; IMAX is what, 70°, so 8k for it is already good enough. Extra resolution is not useful if human eye can't tell the difference; it just gets to the meaningless bragging rights territory like 192 kHz audio and DAC-s with 140 dB+ S/N ratio. Contrast, black levels, shadow details, color accuracy are IMO more important than raw resolution at which modern 8k cameras are good enough and 16k digital cameras will be more than plenty.

1

The extra resolution isn’t completely useless from an editing standpoint.

If you’re working with 16k footage and a 4K deliverable and the shot isn’t quite right you can crop up to 75% of the image with no loss in quality.

This kind of thing would be mostly useful for documentaries, especially nature, or sports where you can’t control the action.

Yeah, we'll have this brief digital gap from the era when film was going out of fashion and 4k and higher resolution digital cameras weren't a thing yet. But now that even average youtubers are shooting 4k with cheap(ish) DSRL-s, we generally don't have to worry about the content having "not good enough quality for the future".

The bigger problem IMO is the ephemeral and profit-driven nature of modern content distribution. Once the studio decides a film/series is not making enough money and pulls it from streaming, it's gone. IIRC, DRM of DCP is also remotely managed so even if a cinema physically has the drive with the movie, they can't play it when the studio pulls the plug--this was not the case with film.

2

Yeah all that is a huge problem, I remember Microsoft pulled the game Scott pilgrim from the Xbox 360 so if you didn't buy it beforehand you couldn't get it anymore until they did some legal stuff to get the game back in the store.

I still think film today is a great tool for getting high resolution photography at a cheap entry cost, a full sized digital sensor camera can be pretty pricey where as a 35mm film camera can be had pretty easy, then once you go to medium format it's gets more expensive and then I'm not even sure there is large format digital cameras

I can't speak for video, but for audio production that isn't true. Audio signals can be perfectly reproduced, up to some frequency determined by the sample rate and up to some noise floor determined by the bit depth, digitally. Set that frequency well beyond that of human hearings and set that noise floor beyond what tape can do or what other factors determine, and you get perfect reproduction.

I don’t know if perfect reproduction necessarily sounds better. It’s probably subjective, but projects I’ve worked on that were tracked with tape have a quality that you can’t get from digital. I’m not talking about tape hiss or anything like that. There’s a roundness to the sound.

True! Analog can distort the audio in a way some people like.

But, it is a distortion. It's not there in the original audio. Sometimes, that is desired though.

Yeah, but they're likely digitally editing it all now, so it loses that in the middle of the process. Can't really see why it would make sense to print a digital file back onto film.

EDIT: I did some reading, some movies have a solution for this!

18
lemmy.world

Despite being what a lot of analog fetishists focus on, a purely analog editing chain is not necessarily what causes the effects that they actually like about analog media. Most of it comes from the playback media itself. In the case of vinyl records, there's mastering techniques that have to be used to make sure the needle stays in the groove that some people feel sound better. There's minute harmonic distortions that people prefer over the perfectly clear and clean sound of digital. In the case of film payback, you have actual image frames being flashed on the screen. You have shutter dwell where no image is shown at all while the next frame is being advanced. You'd never consciously notice the flicker, but it affects the way you perceive the image and the motion on the screen. Film can have very high contrast and there may also be minor differences in color profile due to being displayed by pigments rather than being created digitally. Most digital media these days is technically far superior to it's analog counterpart. It just happens that it's the limitations and artifacts of the analog media that some people find pleasing.

11
guyreply
lemmy.world

Yeah, I like vinyl too. But digital to analog conversion is always imperfect. I don't see that being too fitting for an IMAX cinema, where the aim is just biggest and best, no niche. Aesthetic imperfections are more fitting for arthouse and such I think.

However, I read into it some more now and it's quite interesting. In the case of Oppenheimer, they actually do manage to avoid the digital conversion for much of the film!

For movies shot on film, all of the film negatives are scanned to digital files so that they can be edited using AVID, and the process continues as before. The finished movie can then be "printed" back on to physical film using a laser scanner, which is how most film prints are made these days. However, some filmmakers like Christopher Nolan refuse to use this method, because it doesn't allow you to take full advantage of the resolution of IMAX film. So in Nolan's case, once the movie is finished, an Edit Decision List (EDL) is created, which contains a text list of all the edit points in the film, and which physical pieces of film negative those correspond to. Then, a person called a Negative Cutter actually physically cuts together and assembles the film negative to create the movie in the analog realm. It's a very specialized profession - there are only one or two people in Hollywood that still do it!

4

That's pretty cool. Of course Christopher Nolan would insist on editing on film. I bet Tarantino and a few others would as well. In the case of laser printing vs optical printing, he's probably right, especially at IMAX scale. And you're absolutely right that he's choosing it because it's the highest possible fidelity, whereas someone like Tarantino chooses film for sentimental, kitsch, and artistic reasons. Apparently digital IMAX is still only about 4k at best. In the audio world though, analog DACs really are perfect reproduction many times beyond what is perceptible in sound. Compared to cutting to vinyl from tape, or even transferring from tape to tape, digital is orders of magnitude higher fidelity to the source signal. There's lots of reasons to love analog audio, but higher measurable fidelity is not among them.

Depends on the film itself being used. You can get a pretty insane level of detail on the professional-grade stuff. It's how we're able to do 4K remasters of stuff from decades ago. Digital still has a fair bit to go before it can fully outshine analogue film.

6
lemmy.fmhy.ml

We have such a thing as an 8K camera. It's kinda hard to beat an 8K camera. Especially given film has a very low frame rate, so you're trading one kind of quality for another.

8K is basically more pixels than your ever going to need unless you like staring at a tiny portion of the screen. 24 FPS (films normal FPS fyi) on the other hand is very noticeably different from 60 FPS, nevermind the 120+ FPS some cameras can do.

The reason we have these cameras is partly so we can crop and still get a usable 4K or 6K image.

As for compression we have true lossless and visually lossless formats that are used on professional video cameras. This includes Red Raw.

Did I mention that this kit is cheap enough that Linus Tech Tips - a YouTube channel - can afford to have at least one.

IMAX 1570 film is equivalent to somewhere between 12K and 18K resolution, though as you say that's only going to matter on a really big display or if you're creating content for future VR headsets. As for frame rate, more than 24 FPS doesn't really seem popular in cinema - I remember that Hobbit film getting quite a negative reaction when it tried 48 FPS, and then there's the Soap Opera Effect. The colour characteristics of different kinds of film also appeal to some artistic filmmakers.

None of those points really justify the significantly more expensive and complicated workflow that comes with analogue film, mind. I do wish digital hadn't taken over so soon because a whole bunch of media is now stuck with 480p digital as the best it's realistically ever going to look barring AI upscaling, but I can't say I really blame the producers for making that decision because digital is far less of a pain in the ass.

2
lemmy.fmhy.ml

Nope not even display size can save this, as you need to sit some distance to see the whole thing, unless you only want to look at a portion. The human eye has a finite effective resolution.

VR it could maybe make a difference, even then 8K is good compared to most modern VR devices.

1

VR possibly needs to get as high as 16K to be truly perfect for the human eye, so it could be useful there. But 16K headsets are a long way off, and refresh rate also needs to improve since the human eye can perceive up to 2,000 frames per second, so I feel like refresh rate will be the priority over pixel density by the time we get even 8K headsets.

lemmy.world

While some of what you said is questionable, I do wish more movies were shot in 60+ FPS. Some people clams to prefer 24 FPS, but I honestly think that’s just because we’re so used to it.

1

What have I said is actually questionable? 8K is already beyond the limit of what a human can see at any practical viewing distance. Super high end film might beat it in equivalent resolution, but at that point it's purely academic because you're eyes can't see that much detail.

Unless you want to blow up a small portion of the image to poster size... then I am sure IMAX film is better. Just not sure why you would want that.

Meanwhile in framerate you can see a fairly large difference between the two technologies.

Film is still higher quality than TVs these days. There's a reason it's easy to remaster and rereleasr classic content shot on film than more recent content shot digitally.

To store digitally you would need a compression algorithm. Pretty much all video compression algorithms are lossy, which means you automatically lose detail.

Storing an uncompressed video isn’t feasible as each frame could be hundreds of megabytes (or more) in size. This is due to resolution + color info + audio channels.

2
average650reply
lemmy.world

Many lossless video compression algorithms exist.

https://en.m.wikipedia.org/wiki/List_of_codecs#Lossless_video_compression

Even uncompressed, they would be large, but not unfeasible. Even assuming about 12 MB per frame (reasonable for lossless 4k) that gives us about 1TB per hour. Using lossless video compression would push that smaller. That's very large for consumers, but not for a film studio. I'm certain a few terrabytes Iof storage are way cheaper than that much film.

average650reply
lemmy.world

The color was in fact 16 bit.

If you want 18k, multiple 1TB by (18/4)^2 ish

So more like 20TBs. And again, that's lossleslly compressing the individual images, but not the video. The video is still uncompressed. Lossless video compression would significantly reduce that.

It is a huge file, but it's just as tractable as that film.

10
lemmy.world

An uncompressed 4K frame with 16-bit color is about 50 MB. An uncompressed 18K frame with 16-bit color is just over 1 GB.

I don’t disagree with you that lossless 18K video storage is trivially easy—digital storage is shockingly cheap these days—but I’m curious where you’re getting those numbers from. Compressing an hour of 18K video from 87 TB to 20 TB seems like a remarkable feat.

0

I was using lossless compressed image sizes becuase they were relatively easy to find. So those 4K 16-bit frames were more like 12 MB instead of 50. That's where the compression comes from. Lossless image compression details were much easier to find than losses video compression details, and I could test them myself easily. The 12 MB will depend on the original image, as some compress much more readily than others, but it's reasonable.

The confusing part is there are different types of IMAX's. My nearest cinema has IMAX screens but they are just slightly larger theatre screens for the most part. But downtown there's a 70mm film IMAX and if a film was made for it, I'll go out of my way to see it there - Interstellar and Dunkirk come to mind. Seats are closer to the screen and the aspect ratio is more square, and film just has a certain charm to it.

9

Many years ago, I ended up with a membership to a local museum that had a OMNIMAX theater, which is IMAX, but with a dome and a fisheye lens is used ot shoot the film. The projector is, essentially, in the middle of the room and shoots "up" at the screen / dome at about a 45 degree angle. The net result is the film is pretty much half-a-sphere in front of you. Your entire field of vision is filled by the media.

They almost always showed educational films or documentaries specifically filmed for the format. I specifically recall some stupid one about snowboarding of all things, which was really just an excuse for the filmmakers to go snowboarding and ride helicopters with an expensive movie camera in the mountains. It's very, very cool.

Even if there aren't any major studio movies made for these theaters, if you ever get a chance to see something on one of the few left in operation, take it. Totally worth it.

5

It's still the highest spatial resolution format. The recent laser systems do win for dynamic range, but for sheer detail you'd need roughly the equivalent of 16K while most theater digital projectors are 2K to 4K.

An estimate for "enough" detail when doing foveated rendering is 12K, so 16K uniform is pretty decent.

It's good at home since it can fit the entire 16/9 display.

hmm I thought the point of IMAX is you get the same experience no matter the theater

1

That's a him issue. It's supposed to be fucking loud. When those people go to the lobby and tell them to turn it down, that's when I walk out and buy the midnight ticket.

If I pay to see a movie in an IMAX theater, this is the film being loaded? Is this normal for IMAX?

No. This is called “15/70 Imax”. There are very very few theaters that have this. The “Imax” you’ll find at the local mall is totally different.

I think the theater near Lincoln Center in NYC has this format. I saw 300 there, and something else but I can't remember what. It looks absolutely insane.

Going to see Oppenheimer in imax soon and this post got me researching about imax and fake imax and now im a little disappointed that the imwx theater im going to is just digital imax (fake imax). Oh well :/

25
lemmy.world

I was also disappointed when I checked how many true IMAX theaters the movie is playing in in the US. We have a real IMAX theater in our natural history museum in my city, but Oppenheimer won't be playing there :(

There's one full imax in CT being demolished for a bridge. It is a very necessary bridge that's 125 years old and supports the commuter rail into NYC. I doubt the IMAX will be replaced.

Damn that's the one that's halfway between my brother and I. I was hoping to make it a regular spot.

Probably not. 3 hours of uncompressed 1080p video is around 2tb. The film is closer to 16k which is 64 times more pixels than 1080p. This ain't your web rip off pirate bay.

Surely even a lossless compression is incredibly smaller. (But you can't truly losslessly convert from film to digital, only commenting on uncompressed 1080p.)

However, let's not forget the whole thing was created digitally then "printed" to film, so there was never a "film original".

He uses the camera negative as much as possible and avoids CGI as much as possible so a lot of film hasn’t been digitised and reprinted it’s from the actual source.

Fair point, I hadn't looked up the specific movie / director

2

Christopher Nolan is famously one of the few big Hollywood directors who still shoots much of his footage on actual film, specifically in IMAX.

7

Well, kind of. Nolan does shoot on film, including all of Oppenheimer, but they almost definitely brought it into some digital format for editing before pressing it back onto film in this case.

3

Sure but that's not the point, film is wholly uncompressed. When theaters get 4k digital releases they get mailed a hard drive with the movie on it. "This" wouldn't fit on any card.

10

It's hard to say, but film grain is noisy and noise does not compress well. In my experiments with lossless video compression without film grain you'd get a ~3:1 compression ratio. With film I'd guess closer to 2:1.

So 16k (15360 x 11520) x 12 bit per channel (36) x 24 fps x 3 hours (10800) is 206 TiB. Even with very generous estimates of compression ratios you're not fitting this on anything less than a 2U server filled with storage.

1

Still works if you replace the SD card with an SSD, only slightly larger in comparison to the reel. Of course this ignores any losses when you digitise the film.

3

Not quite, as the other dude said. IMAX is on a whole other level, which is probably why there are so few of them around.

5

Yeah, nah. The equivalent digital copy would be terabytes, and the read speed of a micro SD likely wouldn't be fast enough.

Smaller reels that are spliced together as they're fed on the feed platter you see. My dad was a a projectionist, he'd make these up when a film arrived then break it down to ship it. I'd go on and help him as a kid.

23

Can confirm! I worked projection in high school and college. IIRC the longest one I built was one of the Lord of the Rings movies.

So, in my hometown, we actually have one IMAX theater, and it is within 3 blocks of a Gold's Gym. This is now canon as far as I'm concerned.

A surprising number of films are still shot on film and then transfered to a digital intermediate for editing and later distribution. Not only the few film imax ones. I wonder if anyone is still doing their editing on film, I highly doubt it.

Go watch the movie. A lot of people worked very hard on it. But still, remember to show your support to the strike.

Are they an actual leftist podcast? Not tankies in disguise?

Also looking into it, it's a true crime podcast? Seems an odd name choice if it isn't somewhat related to politics. Unless I've 100% misunderstood the naming convention.

2

It's a reference to the movie "The last house on the left." Not sure about their politics but it's like a horror/paranormal podcast.

7

Not related to politics, they're horror fans - name is a reference to 'Last House on the Left'. They cover anything that's macabre, be it real or fake, so true crime, serial killers, paranormal events, cults, conspiracy theories, cryptids; that sort of thing.

3

As much as I've been able to gather from the .ml Lemmy instances where these people live, extreme communists who defend Chinese and Russian propaganda and deny any atrocities they've committed while railing on America to defend their stance.

Oh we'll get to the sloughing!

(Not nearly as much sloughing as I expected though, tbh. They talked it up way more than actually talking about it, which is fine)

I used to be a projectionist at an art house theater. We just did 16 mm prints. Just imagining this going wrong due to some threading issue and the film going everywhere is giving me anxiety.

12

I used to work as an IMAX projectionist and that has happened. The timings on those projectors are so precise. It’s traveling at about 6ft/sec so it doesn’t take long to make a mess.

I think the whole editing process is digital. They shoot on film, digitize it for editing and print it on film again for IMAX theaters.

lemmy.world

They stopped distributing 35mm film to regular movie theaters in 2014. Only a few modern releases are printed in 70mm IMAX, and only a few IMAX theaters can still project it.

lorezreply

It’s practically useless for viewers. I had a friend who was a projectionist in a theater: they went digital and used both 1080 uncompressed or 4K uncompressed. He pointed me to the different formats when they were projected and we couldn’t tell from the seats. Not imax, just a regular theater with 300 something seats.

1
lemmy.world

Don't they send them on encrypted hard drives these days

It would be more inconvenient shipping that hunk of a thing compared to a hard drive

Then again it makes it easy for the movie to be leaked early by someone since it's not encrypted

Directors that film on Imax generally still have a hard on for physical film.

Not that I blame them. I ran movie theaters for 20 years and while I really did appreciate how much easier my job was after we went digital, I legitimately missed working projection booth shifts when it was all film. Threading and starting two dozen projectors all day long and building prints, it was some of the most fun I ever had at a job. It was really zen, just you and the machines.

36

Back in the days of 35mm film, movies were delivered to theaters in individual reels. A typical movie would be five to seven reels long.

It was my Thursday job to tape all the reels together into one long piece of film for the Friday premier. I'd also have to build the trailer packs, add cues for lights down/up... just generally make sure that the movie would work as it's supposed to.

For reference, you see that platter of film in the OP picture? That platter was delivered in chunks, and building the print is putting all those chunks together to make a complete movie.

I'd absolutely do an AMA if there were a mechanism to do so.

18

Back in a day, movies were projected by chunks. By mean chunks, film reels, either 8mm, 16mm, or 35mm. Some reels have limited celluloid capacity to handle, so multiple reels shipped to theaters. The projectionist taking care of it, assembling the celluloid and project it using bulb.

Fun thing of this, cinemas back then "accidentally" projected those X mark from celluloid.

All it takes is one cinema owner that secretly leaks movies to do it

It's a bit off an off-topic but, can someone explain me the difference between IMAX and iSense? I've googled it but don't fully understand it. How does iSense compare to this beast of an IMAX film reel for example? What about more standard IMAX theatres?

Thanks!

8

The film being that close to the edge of the platter gives me MASSIVE anxiety. I've dealt with brain wraps or film melting in the gate, but those are easy compared to film slinkying off the edge of the platter. Nothing like coming into a booth to find hundreds of feet of film in a rats nest of sadness and rainchecks.

I'm kind of out of the loop. What is the hype around oppenheimer and barbie recently?

4

Christopher Nolan tends to make beautiful IMAX films like Inception or The Dark Knight, and he supposedly put in a lot of effort to simulate a nuclear blast using physical effects and not CG by using massive amounts of dynamite, so people are excited.

Barbie movie is made by Greta Gerwig and the trailer made it out to be a smart satire of the Barbie concept with Margot Robbie and Ryan Gosling as Barbie and Ken. Also they used so much pink paint for the sets that it caused a nationwide shortage of that color (of that one brand only).

Both have a lot of hype and are expected to be top movies of the summer. They happen to overlap on the same opening weekend, which is amusing since they’re such different movies.

Oppenheimer is expected to be really good, mainly because it's made by Christopher Nolan. Barbie is releasing on the same day, so it probably gained some popularity off of that.

3

Lol I don’t think Barbie gained popularity from Oppenheimer. A lot of people are just excited for it, it’s getting advertised a lot lately and it has some crazy aesthetics/vibes.

7

I don't think you quite understand the hold on culture barbie has. Though the two being such polar opposites of each other in vibe and tone likely did boost each other cause of them coming out at the same time.

1

I wish there was a full size imax theater near me, but there isn’t even one in my state. Going to see Oppenheimer in the biggest screen I can, but it not being imax is gonna be rough

4

Dammit I was going to watch Oppenheimer in my local laser IMAX, but this picture made me buy a ticket to Prague to decide for myself if 1570mm worth it :D

3

This reminds me of one of those documentaries where they show some ridiculous mechanical contraption in a scene, and the narrator says, "Before the technology became extinct, it had become vastly more complex and sophisticated, but alas, it's days were numbered..."

Well you could argue making movies is unnecessary altogether. This is art and this is the medium used by the artist.

It's not about image quality of film vs digital, it's about the feel and texture of the experience as a whole.

Just knowing there is an actual film being rolled and having light shun through it while watching it is part of that experience.

If you can't tell the difference on the screen it should make no damn odds how the image was stored.

lemdro.id

I disagree. Have you ever been to a real 70mm IMAX screening? I don't mean your typical "IMAX". There's only a handful in the whole world.

The quality is gorgeous, and the screens are huge. You also get significantly more of the frame than you will in traditional cinema and on bluray releases.

Don't call it unnecessary until you've actually seen it. Digital IMAX isn't close yet.

2
arcreply

The reason it's unnecessary is that digital can completely capture a 70mm in high enough resolution that you perceive no difference at all. 8 or 16K projection is completely feasible in commercial projection systems. It means the cinema only has to deal with a small box instead of an enormous roll of film.

That doesn't mean either digital IMAX since that's old tech using something like 2K projection which isn't adequate.

2

What’s the point of even doing it on film if it was shot digitally?

Or did they go through the whole process using analog technology? I don’t know much about this movie.
