Flashback to the old days (1 month ago)
Joey refugee here, this was only 24 h ago
Or approximately 2400 cheeseburgers for the Americans in the audience.
That’s almost a years worth!
272 kg ~ 43 stone
43 stone ~ 1.4 boulder
2 boulders = 1 pair boobies
According to this the average pair of boobies is 860 pounds, sounds about right.
How many pebbles?
86 in the winter, 87 daylight savings time
I understand 600lbs. Kgs mean nothing to me.
I understand 272 kg. Lbs mean nothing to me. :)
I didn’t realize imax was still film. I figured it went digital with everything else.
70mm film to be exact
15/70mm film to be exact. IMAX 15/70mm is different to standard 5/70mm you would get in a normal cinema.
I’ve not really been into films but recently I’ve started to pay more attention to directors and screen writers.
I really want to watch Oppenheimer as it interests me but I really really want to watch it on 70mm IMAX, I am lucky enough to love 6 miles away from one and I don’t know if it will be that good or if the marketing team has done a hell of a job.
I’ve been watching videos and reading up about IMAX and cinematography. Every showing is booked up for the first week that I checked. Even the 7am showings.
How good is 70mm imax
70mm is the equivalent of shooting 18k digitally
there are both, the top end is still film though as far as I understand
Our local one did, but I guess not all. It’s a shame, you used to be able to watch the film being wound through windows
You can still do it through Linux, if you know the right commands…
That will fit nicely in my 32gb micro sdxc the size of a fingernail.
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
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).

True but you won’t lose the film roll that easy
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.
If you can see the film print in the opening week. Christopher Nolan makes his movies in an analog way. So it is a film process all the way though except for VFX. This is one of the only opportunities to see film that was not digitally modified. Only one place in the world can make these imax 70mm film prints and they are all basically hand made. EDIT: link changed to piped link. https://piped.video/watch?v=xa1xJIgLzFk
2k digital projection is typically used in smaller theaters where the screen size is not large enough for anyone to actually see a difference.
I’m going to see it in 70mm on the 28th and I’m sooo fucking excited! I got center seats near the back too, it’s gonna be epic. I wish there were more 70mm IMAX theaters so more people could experience it but I understand why there aren’t lol

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?

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.
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.
That is what I did, just make sure that you can get a spare bulb for reasonable money. Some old projectors have EXPENSIVE bulbs
If I pay to see a movie in an IMAX theater, this is the film being loaded? Is this normal for IMAX?
Check out this list. The imax 70mm ones would be reels like this one.

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.
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…”
A lot of the time, the complexity is the main reason something goes bye bye; something just as sophisticated comes along, but is far less complex. Making it less prone to failure/easier to use/implement.
Seeing this tonight and cannot wait!
Guessing this will beat Interstellar record for longest IMAX film. Interstellar has the record being 2 hours and 47 minutes. But looks like Oppenheimer is 3 hours long.
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!
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 was watching this video on IMAX film and noticed that the outside film is actually fixed in place and the reel unspools from the center and fills up the reel on the other rack. So fortunately it isn’t possible for it to unspools from the outside.
https://youtu.be/gENOhw1Q3vMCorrect. That’s how most 35mm projectors work as well. The film feeds out from the middle of one platter, through the projector then onto a return platter where it spools from the center out. But if the tail of the film (which is on the outer edge) comes loose and falls off the edge it could cause the entire print to spin off the edge of the platter, one layer at a time. It’s like a slinky, the weight of the film falling will make it fall faster and faster. It would end up in a big circular pile that would be an absolute nightmare to get back on the platter.
There’s nothing worse than coming into the booth and finding hundreds of feet of film tangled on the ground.
Ah, that’s interesting and definitely sounds like an awful mess to deal with. Thanks for sharing, I’m not as familiar with film projection.
Thank you for taking a few moments to learn about it yourself! The link you provided to the Imax video wasn’t one I’d seen before, and I love watching that kind of shit.
I’m kind of out of the loop. What is the hype around oppenheimer and barbie recently?
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.
have you seen the trailers? barbie actually looks good as shit - the first teaser was a shot for shot recreation of 2001: A Space Odyssey trailer https://www.youtube.com/watch?v=I6vPuIMAOlA
Pretty unnecessary in this digital age
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.
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.
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.
All of this could fit on a micro SD card.
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
Christopher Nolan is famously one of the few big Hollywood directors who still shoots much of his footage on actual film, specifically in IMAX.
This is insane. I want to go watch this in IMAX so badly, but there are no IMAX theaters anywhere near me. Maybe one day I’ll get a chance. Do they ever reshow older IMAX movies? Like, I would kill to go back and see Interstellar or Dark Knight.
Why do people get so hyped for IMAX? There’s gotta be something more to it than just an even bigger screen, right?
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.
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.
It basically a badge for a more premium film experience. It’s a bigger screen, on an aspect ratio that fills the vision, with seating that puts you in the right place, rather than trying to see over the person in front.
Huh, yeah I’ll just stay on my couch.
That’s as premium as it gets: deep OLED color, pulled pork out of the crock pot, blankets to curl up with, the works.
It’s good at home since it can fit the entire 16/9 display.
I dunno man, I’ve been to IMAX to see Dune in and it was so fucking loud i had to leave after 15 minutes, even with 1100 3M ear plugs which are like -30db.
That’s a theatre issue, not an IMAX one.
I’m sure I’m wrong, but it’s hard to imagine this being better quality than what we can do digitally these days.
You are in fact wrong lol. Actual film has a resolution equivalent of something like 18K.
Wasn’t normal 35mm film about the equivalent of somewhere between 4k and 8k depending on the film stock?
Plus, the projector optics will always limit the sharpness of the picture. No lense is ideal, and even ideal lenses would have fundamental limitations due to diffraction.
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.
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.
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.
I don’t think there’s any reason we couldn’t make a store 18k video.
And we could make screen at much higher resolutions that that at imax size, or even quite a bit smaller, though I suspect it would be absurdly expensive.
Storing it isn’t the problem, you’ll still need to be able to record and project at that resolution.
As I said I’m sure we could make screens that could do that. They would be absurdly expensive and heavy and stupid, but it could be done. Not worth it though.
And it looks like at least 16k cameras have been made.
The screens aren’t the problem. It’s often the hardware driving it. The current top generation of gaming gpus struggles at 8k. There’s very little chance of being able to render and play 16/18k
Rendering video and rendering games are pretty different. Video is generally easier especially once it’s mixed down.
Not enough to justify using such a proprietary technology
proprietary technology
Not like the off the shelf stuff you can get to store and show 18K.
